China (i/ˈtʃaɪnə/; Chinese: 中国; pinyin: Zhōngguó; see also Names of China), officially the People's Republic of China (PRC), is the world's most-populous country, with a population of over 1.3 billion. Covering approximately 9.6 million square kilometres, the East Asian state is the world's second-largest country by land area,[13] and the third- or fourth-largest in total area, depending on the definition of total area.[14]
The People's Republic of China is a single-party state governed by the Communist Party of China.[15] It exercises jurisdiction over 22 provinces, five autonomous regions, four directly controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau).[16] Its capital city is Beijing.[17] The PRC also claims Taiwan—which is controlled by the Republic of China (ROC), a separate political entity—as its 23rd province, a claim controversial due to the complex political status of Taiwan and the unresolved Chinese Civil War. The PRC government denies the legitimacy of the ROC.
China's landscape is vast and diverse, with forest steppes and the Gobi and Taklamakan deserts occupying the arid north and northwest near Mongolia and Central Asia, and subtropical forests being prevalent in the wetter south near Southeast Asia. The terrain of western China is rugged and elevated, with the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separating China from South and Central Asia. The world's apex, Mt. Everest (8,848 m), lies on the China–Nepal border, while the world's second-highest point, K2 (8,611 m), is situated on China's border with Pakistan. The country's lowest and the world's third-lowest point, Lake Ayding (−154 m), is located in the Turpan Depression. The Yangtze and Yellow Rivers, the third- and sixth-longest in the world, have their sources in the Tibetan Plateau and continue to the densely populated eastern seaboard. China's coastline along the Pacific Ocean is 14,500 kilometres (9,000 mi) long—the 11th-longest in the world—and is bounded by the Bohai, Yellow, East and South China Seas.
The nation of China has had numerous historical incarnations. The ancient Chinese civilization—one of the world's earliest—flourished in the fertile basin of the Yellow River in the North China Plain.[18] China's political system was based on hereditary monarchies, known as dynasties, beginning with the semi-mythological Xia of the Yellow River basin (approx. 2000 BC) and ending with the fall of the Qing Dynasty in 1911. Since 221 BC, when the Qin Dynasty first conquered several states to form a Chinese empire, the country has expanded, fractured and been reformed numerous times. The Republic of China, founded in 1911 after the overthrow of the Qing dynasty, ruled the Chinese mainland until 1949. In 1945, the ROC acquired Taiwan from Japan following World War II.
In the 1946–1949 phase of the Chinese Civil War, the Chinese Communist Party defeated the nationalist Kuomintang in mainland China and established the People's Republic of China in Beijing on 1 October 1949. The Kuomintang relocated the ROC government to Taiwan, establishing its capital in Taipei. The ROC's jurisdiction is now limited to Taiwan and several outlying islands, including Penghu, Kinmen and Matsu. Since 1949, the People's Republic of China and the Republic of China (now widely known as "Taiwan") have remained in dispute over the sovereignty of China and the political status of Taiwan, mutually claiming each other's territory and competing for international diplomatic recognition. In 1971, the PRC gained admission to the United Nations and took the Chinese seat as a permanent member of the U.N. Security Council. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organisation, the BCIM and the G-20. As of September 2011, all but 23 countries have recognized the PRC as the sole legitimate government of China.
Since the introduction of market-based economic reforms in 1978, China has become the world's fastest-growing major economy.[19] As of 2012, it is the world's second-largest economy, after the United States, by both nominal GDP and purchasing power parity (PPP),[20] and is also the world's largest exporter and second-largest importer of goods. In per capita terms, China ranked 90th by nominal GDP and 91st by GDP (PPP) in 2011, according to the IMF. China is a recognized nuclear weapons state and has the world's largest standing army, with the second-largest defense budget. In 2003, China became the third nation in the world, after the former Soviet Union and the United States, to independently launch a successful manned space mission. China has been characterized as a potential superpower by a number of academics,[21] military analysts,[22] and public policy and economics analysts.[23]

The word "China" is derived from Cin (چین), a Persian name for China popularized in medieval Europe by the account of the 13th-century Venetian explorer Marco Polo.[26][27] The first recorded use in English dates from 1555.[28] The Persian word is, in turn, derived from the Sanskrit word Cīna (चीन),[29] which was used as a name for China as early as AD 150.[30] There are various scholarly theories regarding the origin of this word. The traditional theory, proposed in the 17th century by Martino Martini, is that "China" is derived from "Qin" (秦), the westernmost of the Chinese kingdoms during the Zhou Dynasty, or from the succeeding Qin Dynasty (221–206 BC).[31] The word Cīna is used in two Hindu scriptures – the Mahābhārata of the 5th century BC and the Laws of Manu of the 2nd century BC – to refer to a country located in the Tibetan-Burman borderlands east of India.[32][33]
In China, common names for the country include Zhōngguó (Chinese: 中国; literally "the Central State(s)") and Zhōnghuá (Chinese: 中华), although the country's official name has been changed numerous times by successive dynasties and modern governments. The term Zhongguo appeared in various ancient texts, such as the Classic of History of the 6th century BC,[34] and in pre-imperial times it was often used as a cultural concept to distinguish the Huaxia from the barbarians. The term, which can be either singular or plural, referred to the group of states in the central plain. It was only in the nineteenth century that the term emerged as the formal name of the country. The Chinese were not unique in regarding their country as "central", since other civilizations had the same view.[35]
Archaeological evidence suggests that early hominids inhabited China between 250,000 and 2.24 million years ago.[36] A cave in Zhoukoudian (near present-day Beijing) exhibits fossils dated at between 300,000 and 780,000 BC.[37][38][39] The fossils are of Peking Man, an example of Homo erectus who used fire. There are also remains of Homo sapiens dating back to 18,000–11,000 BC found at the Peking Man site.[40]
Chinese tradition names the first dynasty Xia, but it was considered mythical until scientific excavations found early Bronze Age sites at Erlitou in Henan Province in 1959.[41] Archaeologists have since uncovered urban sites, bronze implements, and tombs in locations cited as Xia's in ancient historical texts, but it is impossible to verify that these remains are of the Xia without written records from the period.
The first Chinese dynasty that left historical records, the loosely feudal Shang (Yin), settled along the Yellow River in eastern China from the 17th to the 11th century BC. The oracle bone script of the Shang Dynasty represent the oldest forms of Chinese writing found and the direct ancestor of modern Chinese characters used throughout East Asia. The Shang were invaded from the west by the Zhou, who ruled from the 12th to the 5th century BC, until their centralized authority was slowly eroded by feudal warlords. Many independent states eventually emerged out of the weakened Zhou state, and continually waged war with each other in the Spring and Autumn Period, only occasionally deferring to the Zhou king. By the time of the Warring States Period, there were seven powerful sovereign states, each with its own king, ministry and army.
The first unified Chinese state was established by Qin Shi Huang of the Qin state in 221 BC. Qin Shi Huang proclaimed himself the "First Emperor" (始皇帝), and imposed many reforms throughout China, notably the forced standardization of the Chinese language, measurements, length of cart axles, and currency. The Qin Dynasty lasted only fifteen years, falling soon after Qin Shi Huang's death, as its harsh legalist and authoritarian policies led to widespread rebellion.[42][43]
The subsequent Han Dynasty ruled China between 206 BC and 220 AD, and created a lasting Han cultural identity among its populace that extends to the present day.[42][43] The Han Dynasty expanded the empire's territory considerably with military campaigns reaching Korea, Vietnam, Mongolia and Central Asia, and also helped establish the Silk Road in Central Asia. China was for a large part of the last two millennia the world's largest economy.[44] However, in the later part of the Qing Dynasty, China's economic development began to slow and Europe's rapid development during and after the Industrial Revolution enabled it to surpass China.
After the collapse of Han, another period of disunion followed, including the highly chivalric period of the Three Kingdoms.[45] Independent Chinese states of this period such as Wu opened diplomatic relations with Japan,[46] introducing the Chinese writing system there. In 580 AD, China was reunited under the Sui.[47] However, the Sui Dynasty was short-lived after a failure in the Goguryeo-Sui Wars (598–614) weakened it.[48][49]
Under the succeeding Tang and Song dynasties, Chinese technology and culture reached its zenith.[50] The Tang Empire was at its height of power until the middle of the 8th century, when the An Shi Rebellion destroyed the prosperity of the empire.[51] The Song Dynasty was the first government in world history to issue paper money and the first Chinese polity to establish a permanent standing navy.[52] Between the 10th and 11th centuries, the population of China doubled in size. This growth came about through expanded rice cultivation in central and southern China, and the production of abundant food surpluses.
Within its borders, the Northern Song Dynasty had a population of some 100 million people. The Song Dynasty was a culturally rich period for philosophy and the arts. Landscape art and portrait painting were brought to new levels of maturity and complexity after the Tang Dynasty, and social elites gathered to view art, share their own, and trade precious artworks. Philosophers such as Cheng Yi and Chu Hsi reinvigorated Confucianism with new commentary, infused Buddhist ideals, and emphasized a new organization of classic texts that brought about the core doctrine of Neo-Confucianism.
In 1271, the Mongol leader and fifth Khagan of the Mongol Empire Kublai Khan established the Yuan Dynasty, with the last remnant of the Song Dynasty falling to the Yuan in 1279. Before the Mongol invasion, Chinese dynasties reportedly had approximately 120 million inhabitants; after the conquest was completed in 1279, the 1300 census reported roughly 60 million people.[53]
A peasant named Zhu Yuanzhang overthrew the Yuan Dynasty in 1368 and founded the Ming Dynasty.[54] Ming Dynasty thinkers such as Wang Yangming would further critique and expand Neo-Confucianism with ideas of individualism and innate morality that would have tremendous impact on later Japanese thought. Chosun Korea also became a nominal vassal state of Ming China and adopted much of its Neo-Confucian bureaucratic structure.
Under the Ming Dynasty, China enjoyed another golden age, developing one of the strongest navies in the world and a rich and prosperous economy amid a flourishing of art and culture. It was during this period that Zheng He led explorations throughout the world, possibly reaching America. During the early Ming Dynasty, China's capital was moved from Nanjing to Beijing. In 1644, Beijing was sacked by a coalition of rebel forces led by Li Zicheng, a minor Ming official turned leader of the peasant revolt. The last Ming Chongzhen Emperor committed suicide when the city fell. The Manchu Qing Dynasty then allied with Ming Dynasty general Wu Sangui and overthrew Li's short-lived Shun Dynasty, and subsequently seized control of Beijing, which became the new capital of the Qing Dynasty.
The Qing Dynasty, which lasted until 1912, was the last imperial dynasty of China. In the 19th century, the Qing Dynasty adopted a defensive posture towards European imperialism, even though it engaged in an imperialistic expansion of its own into Central Asia. At this time, China awoke to the significance of the rest of the world, the West in particular. As China opened up to foreign trade and missionary activity, opium produced by British India was forced onto Qing China. Two Opium Wars with Britain weakened the Emperor's control. European imperialism proved to be disastrous for China:
The Arrow War (1856–1860) [2nd Opium War] saw another disastrous defeat for China. The subsequent passing of the humiliating Treaty of Tianjin in 1856 and the Beijing Conventions of 1860 opened up more of the country to foreign penetrations and more ports for their vessels. Hong Kong was ceded over to the British. Thus, the "unequal treaties system" was established. Heavy indemnities had to be paid by China, and more territory and control were taken over by the foreigners.[55]
The weakening of the Qing regime, and the apparent humiliation of the unequal treaties in the eyes of the Chinese people had several consequences. One consequence[according to whom?] was the Taiping Rebellion, a civil war which lasted from 1851 to 1862. The rebellion was led by Hong Xiuquan, who was partly influenced by an idiosyncratic interpretation of Christianity. Hong believed himself to be the son of God and the younger brother of Jesus. Although the Qing forces were eventually victorious, the civil war was one of the bloodiest in human history, costing at least 20 million lives (more than the total number of fatalities in World War I), with some estimates of up to two hundred million. Other costly rebellions followed the Taiping Rebellion, such as the Punti-Hakka Clan Wars (1855–67), Nien Rebellion (1851–1868), Miao Rebellion (1854–73), Panthay Rebellion (1856–1873) and the Dungan revolt (1862–1877).[56][57]
These rebellions resulted in an estimated loss of several million lives each and led to disastrous results for the economy and the countryside.[58][59][60] The flow of British opium hastened the empire's decline. In the 19th century, the age of colonialism was at its height and the great Chinese Diaspora began; today, about 35 million overseas Chinese live in Southeast Asia.[61] Emigration rates were strengthened by domestic catastrophes such as the famine of 1876–79, which claimed between 9 and 13 million lives in northern China.[62] From 108 BC to 1911 AD, China experienced 1,828 famines,[63] or one per year, somewhere in the empire.[64]
While China was wracked by continuous war, Meiji Japan succeeded in rapidly modernizing its military, and set its sights on the conquest of Korea and Manchuria. At the request of the Korean emperor, the Qing government sent troops to aid in suppressing the Tonghak Rebellion in 1894. However, Japan also sent troops to Korea, leading to the First Sino-Japanese War, which resulted in Qing China's loss of influence in the Korean Peninsula as well as the cession of Taiwan (including the Pescadores) to Japan.
Following this series of defeats, a reform plan for the empire to become a modern Meiji-style constitutional monarchy was drafted by the Guangxu Emperor in 1898, but was opposed and stopped by the Empress Dowager Cixi, who placed Emperor Guangxu under house arrest in a coup d'état. Further destruction followed the ill-fated 1900 Boxer Rebellion against westerners in Beijing.
By the early 20th century, mass civil disorder had begun, and calls for reform and revolution were heard across the country. The 38-year-old Emperor Guangxu died under house arrest on 14 November 1908, suspiciously just a day before Cixi's own death. With the throne empty, he was succeeded by Cixi's handpicked heir, his two year old nephew Puyi, who became the Xuantong Emperor. Guangxu's consort became the Empress Dowager Longyu. In another coup de'tat, Yuan Shikai overthrew the last Qing emperor, and forced empress Dowager Longyu to sign the abdication decree as regent in 1912, ending two thousand years of imperial rule in China. She died, childless, in 1913.

On 1 January 1912, the Republic of China was established, heralding the end of Imperial China. Sun Yat-sen of the Kuomintang (the KMT or Nationalist Party) was proclaimed provisional president of the republic. However, the presidency was later given to Yuan Shikai, a former Qing general, who had ensured the defection of the entire Beiyang Army from the Qing Empire to the revolution. In 1915, Yuan proclaimed himself Emperor of China, but was forced to abdicate and reestablish the republic in the face of popular condemnation, not only from the general population but also from among his own Beiyang Army and its commanders.
After Yuan Shikai's death in 1916, China was politically fragmented, with an internationally recognized but virtually powerless national government seated in Beijing. Regional warlords exercised actual control over their respective territories. In the late 1920s, the nationalist Kuomintang, under Chiang Kai-shek, was able to reunify the country under its own control with a series of deft military and political maneuverings, known collectively as the Northern Expedition. The Kuomintang moved the nation's capital to Nanjing and implemented "political tutelage", an intermediate stage of political development outlined in Sun Yat-sen's San-min program for transforming China into a modern democratic state. Effectively, political tutelage meant one-party rule by the Kuomintang, but the party was politically divided into competing cliques. This political division made it difficult for Chiang to battle the Communists, which the Kuomintang had been warring against since 1927 in the Chinese Civil War. This war continued successfully for the Kuomintang, especially after the Communists were forced to retreat in the Long March, until the Xi'an Incident and Japanese aggression forced Chiang to confront Imperial Japan.
The Second Sino-Japanese War (1937–1945), a part of World War II, forced an uneasy alliance between the Kuomintang and the Communists. The Japanese "three-all policy" in northern China—"kill all, burn all and destroy all"—led to numerous war atrocities being committed against the civilian population; in all, as many as 20 million Chinese civilians were killed.[65][66] An estimated 200,000 Chinese were massacred in the city of Nanjing alone during the Japanese occupation.[67] Japan unconditionally surrendered to China in 1945. Taiwan, including the Pescadores, was retroceded. China emerged victorious but war-ravaged and financially drained. The continued distrust between the Kuomintang and the Communists led to the resumption of the Chinese Civil War. In 1947, constitutional rule was established, but because of the ongoing Civil War many provisions of the ROC constitution were never implemented in mainland China.[citation needed]
Major combat in the Chinese Civil War ended in 1949 with the Communist Party in control of mainland China, and the Kuomintang retreating offshore, reducing the ROC's territory to only Taiwan, Hainan, and their surrounding islands. On 1 October 1949, Mao Zedong proclaimed the People's Republic of China,[68] which was commonly known in the West as "Communist China" or "Red China" during the Cold War.[69] In 1950, the People's Liberation Army succeeded in capturing Hainan from the ROC, occupying Tibet, and defeating the majority of the remaining Kuomintang forces in Yunnan and Xinjiang provinces, though some Kuomintang holdouts survived until much later.
Mao encouraged population growth, and under his leadership the Chinese population almost doubled from around 550 million to over 900 million.[70] However, Mao's Great Leap Forward, a large-scale economic and social reform project, resulted in an estimated 45 million deaths between 1958 and 1961, mostly from starvation.[71] In 1966, Mao and his allies launched the Cultural Revolution, which would last until Mao's death a decade later. The Cultural Revolution, motivated by power struggles within the Party and a fear of the Soviet Union, led to a major upheaval in Chinese society. In October 1971, the PRC replaced the Republic of China in the United Nations, and took its seat as a permanent member of the Security Council. In that same year, for the first time, the number of countries recognizing the PRC surpassed those recognizing the ROC in Taipei as the government of China.[72] In February 1972, at the peak of the Sino-Soviet split, Mao and Zhou Enlai met Richard Nixon in Beijing. However, the U.S. did not officially recognise the PRC as China's sole legitimate government until 1 January 1979.
After Mao's death in 1976 and the arrest of the Gang of Four, who were blamed for the excesses of the Cultural Revolution, Deng Xiaoping quickly wrested power from Mao's anointed successor Hua Guofeng. Although he never became the head of the party or state himself, Deng was in fact the Paramount Leader of China at that time, his influence within the Party led the country to significant economic reforms. The Communist Party subsequently loosened governmental control over citizens' personal lives and the communes were disbanded with many peasants receiving multiple land leases, which greatly increased incentives and agricultural production. This turn of events marked China's transition from a planned economy to a mixed economy with an increasingly open market environment, a system termed by some "market socialism";[73] the Communist Party of China officially describes it as "socialism with Chinese characteristics". China adopted its current constitution on 4 December 1982.
The death of pro-reform official Hu Yaobang helped to spark the Tiananmen Square protests of 1989, during which students and others campaigned for several months, speaking out against corruption and in favour of greater political reform, including democratic rights and freedom of speech. However, they were eventually put down on 4 June when PLA troops and vehicles entered and forcibly cleared the square, resulting in numerous casualties. This event was widely reported and brought worldwide condemnation and sanctions against the government.[74][75] The "Tank Man" incident in particular became famous.
President Jiang Zemin and Premier Zhu Rongji, both former mayors of Shanghai, led the nation in the 1990s. Under Jiang and Zhu's ten years of administration, China's economic performance pulled an estimated 150 million peasants out of poverty and sustained an average annual gross domestic product growth rate of 11.2%.[76][77] The country formally joined the World Trade Organization in 2001.
Although rapid economic growth has made the Chinese economy the world's second-largest, this growth has also severely impacted the country's resources and environment.[78] Another concern is that the benefits of economic development has not been distributed evenly, resulting in a wide development gap between urban and rural areas. As a result, under President Hu Jintao and Premier Wen Jiabao, the Chinese government initiated policies to address these issues of equitable distribution of resources, though the outcome remains to be seen.[79] More than 40 million farmers have been displaced from their land,[80] usually for economic development, contributing to the 87,000 demonstrations and riots across China in 2005.[81] Living standards have improved significantly but political controls remain tight.[82]
The People's Republic of China is the second-largest country in the world by land area after Russia[13] and is either the third- or fourth-largest by total area, after Russia, Canada and, depending on the definition of total area, the United States.[83] China's total area is generally stated as being approximately 9,600,000 km2 (3,700,000 sq mi).[84] Specific area figures range from 9,572,900 km2 (3,696,100 sq mi) according to the Encyclopædia Britannica,[85] 9,596,961 km2 (3,705,407 sq mi) according to the UN Demographic Yearbook,[86] to 9,596,961 km2 (3,705,407 sq mi) according to the CIA World Factbook,[87] and 9,640,011 km2 (3,722,029 sq mi) including Aksai Chin and the Trans-Karakoram Tract, which are controlled by China and claimed by India.[88] None of these figures include the 1,000 square kilometres (386.1 sq mi) of territory ceded to China by Tajikistan following the ratification of a Sino-Tajik border agreement in January 2011.[89]
According to the Encyclopædia Britannica, the total area of the United States, at 9,522,055 km2 (3,676,486 sq mi), is slightly smaller than that of China. Meanwhile, the CIA World Factbook states that China's total area was greater than that of the United States until the coastal waters of the Great Lakes was added to the United States' total area in 1996.[90]
China has the longest combined land border in the world, measuring 22,117 km (13,743 mi) from the mouth of the Yalu River to the Gulf of Tonkin. China borders 14 nations, more than any other country except Russia, which also borders 14. China extends across much of East Asia, bordering Vietnam, Laos, and Burma in Southeast Asia; India, Bhutan, Nepal and Pakistan[91] in South Asia; Afghanistan, Tajikistan, Kyrgyzstan and Kazakhstan in Central Asia; a small section of Russian Altai and Mongolia in Inner Asia; and the Russian Far East and North Korea in Northeast Asia.
Additionally, China shares maritime boundaries with South Korea, Japan, Vietnam and the Philippines. The PRC and the Republic of China (Taiwan) make mutual claims over each other's territory and the frontier between areas under their respective control is closest near the islands of Kinmen and Matsu, off the Fujian coast, but otherwise run through the Taiwan Strait. The PRC and ROC assert identical claims over the entirety of the Spratly Islands in the South China Sea, and the southern-most extent of these claims reach Zengmu Ansha (James Shoal), which would form a maritime frontier with Malaysia.
The territory of China lies between latitudes 18° and 54° N, and longitudes 73° and 135° E. China's landscapes vary significantly across its vast width. In the east, along the shores of the Yellow Sea and the East China Sea, there are extensive and densely populated alluvial plains, while on the edges of the Inner Mongolian plateau in the north, broad grasslands predominate. Southern China is dominated by hills and low mountain ranges, while the central-east hosts the deltas of China's two major rivers, the Yellow River and the Yangtze River. Other major rivers include the Xi, Mekong, Brahmaputra and Amur. To the west, major mountain ranges, most notably the Himalayas, and high plateaus feature among the more arid landscapes of the north, such as the Taklamakan and the Gobi Desert. China's highest point, Mt. Everest (8848m), lies on the Sino-Nepalese border. The country's lowest point is the dried lake bed of Ayding Lake (−154m) in the Turpan Depression.
A major environmental issue in China is the continued expansion of its deserts, particularly the Gobi Desert, which is currently the world's fifth-largest desert.[92][93] Although barrier tree lines planted since the 1970s have reduced the frequency of sandstorms, prolonged drought and poor agricultural practices have resulted in dust storms plaguing northern China each spring, which then spread to other parts of East Asia, including Korea and Japan. According to China's environmental watchdog, Sepa, China is losing a million acres (4,000 km²) per year to desertification.[94] Water quality, erosion, and pollution control have become important issues in China's relations with other countries. Melting glaciers in the Himalayas could potentially lead to water shortages for hundreds of millions of people.[95]
China's climate is mainly dominated by dry seasons and wet monsoons, which lead to a pronounced temperature differences between winter and summer. In the winter, northern winds coming from high-latitude areas are cold and dry; in summer, southern winds from coastal areas at lower latitudes are warm and moist. The climate in China differs from region to region because of the country's extensive and complex topography.
China is one of 17 megadiverse countries,[96] lying in two of the world's major ecozones: the Palearctic and the Indomalaya. In the Palearctic zone, mammals such as the horse, camel, tapir, and jerboa can be found. Among the species found in the Indomalaya region are the Leopard Cat, bamboo rat, treeshrew, and various monkey and ape species. Some overlap exists between the two regions due to natural dispersal and migration; deer, antelope, bears, wolves, pigs, and numerous rodent species can all be found in China's diverse climatic and geological environments. The famous giant panda is found only in a limited area along the Yangtze River. China suffers from a continuing problem with trade in endangered species, although there are now laws to prohibit such activities.
China also hosts a variety of forest types. Cold coniferous forests predominate in the north of the country, supporting animal species such as moose and the Asian black bear, along with over 120 bird species. Moist conifer forests can have thickets of bamboo as an understorey, replaced by rhododendrons in higher montane stands of juniper and yew. Subtropical forests, which dominate central and southern China, support as many as 146,000 species of flora. Tropical and seasonal rainforests, though confined to Yunnan and Hainan Island, contain a quarter of all the plant and animal species found in China.
In recent decades, China has suffered from severe environmental deterioration and pollution.[97] While regulations such as the 1979 Environmental Protection Law are fairly stringent, enforcement of them is poor, as they are frequently disregarded by local communities and government officials in favour of rapid economic development.
Environmental campaigners such as Ma Jun have warned of the danger that water pollution poses to Chinese society.[98] According to the Chinese Ministry of Water Resources, roughly 300 million Chinese do not have access to safe drinking water, and 40% of China’s rivers have been polluted by industrial and agricultural waste as of late 2011.[99] This crisis is compounded by the perennial problem of water shortages, with 400 out of 600 surveyed Chinese cities reportedly short of drinking water.[100][101]
However, China is the world's leading investor in renewable energy technologies, with $34.6 billion invested in 2009 alone.[102][103] China produces more wind turbines and solar panels than any other country,[104] and renewable energy projects, such as solar water heating, are widely pursued at the local level.[105] By 2009, over 17% of China's energy was derived from renewable sources – most notably hydroelectric power plants, of which China has a total installed capacity of 197 GW.[106] In 2011, the Chinese government announced plans to invest four trillion yuan (US$618.55 billion) in water infrastructure projects over a ten-year period, and to complete construction of a flood prevention and anti-drought system by 2020.[107]
The People's Republic of China, along with Vietnam, North Korea, Laos, and Cuba, is one of the five remaining official Communist states in the world.[108][109] but simple characterizations of China's political structure since the 1980s are no longer possible.[10] The Chinese government has been variously described as communist and socialist, but also as authoritarian, with heavy restrictions remaining in many areas, most notably on the Internet, the press, freedom of assembly, reproductive rights, and freedom of religion.[110] Its current political/economic system has been termed by its leaders as "Socialism with Chinese characteristics".
Compared to its closed-door policies until the mid-1970s, the liberalization of China has resulted in the administrative climate being less restrictive than before. China is far different from liberal democracy or social democracy that exists in most of Europe or North America, and the National People's Congress (highest state body) has been described as a "rubber stamp" body.[111] China's incumbent President is Hu Jintao, who is also the General Secretary of the Communist Party of China, and its Premier is Wen Jiabao, who is also a senior member of the CPC Politburo Standing Committee.
The country is ruled by the Communist Party of China (CPC), whose power is enshrined in China's constitution.[112] The Chinese electoral system is hierarchical, whereby local People's Congresses are directly elected, and all higher levels of People's Congresses up to the National People's Congress (NPC) are indirectly elected by the People's Congress of the level immediately below.[113] The political system is partly decentralized,[114] with limited democratic processes internal to the party and at local village levels, although these experiments have been marred by corruption. There are other political parties in China, referred to in China as democratic parties, which participate in the National People's Congress and the Chinese People's Political Consultative Conference (CPPCC).
There have been some moves toward political liberalization, in that open contested elections are now held at the village and town levels,[115][116] and that legislatures have shown some assertiveness from time to time. However, the Party retains effective control over government appointments: in the absence of meaningful opposition, the CPC wins by default most of the time. Political concerns in China include lessening the growing gap between rich and poor and fighting corruption within the government leadership.[117]
The level of support to the government action and the management of the nation is among the highest in the world, with 86% of people who express satisfaction with the way things are going in their country and with their nation's economy according to a 2008 Pew Research Center survey.[118]
The People's Republic of China has administrative control over 22 provinces, and considers Taiwan to be its 23rd province, although Taiwan is currently governed by the Republic of China, which disputes the PRC's claim.[119] China also has five subdivisions officially termed autonomous regions, each with a designated minority group; four municipalities; and two Special Administrative Regions (SARs), which enjoy a degree of political autonomy. These 22 provinces, five autonomous regions, and four municipalities can be collectively referred to as "mainland China", a term which usually excludes the SARs of Hong Kong and Macau.

China has diplomatic relations with 171 countries and maintains embassies in 162.[120] Its legitimacy is disputed by the Republic of China and a few other countries; it is thus the largest and most populous state with limited recognition. Sweden was the first western country to establish diplomatic relations with the People's Republic on 9 May 1950.[121] In 1971, the PRC replaced the Republic of China as the sole representative of China in the United Nations and as one of the five permanent members of the United Nations Security Council.[122] China was also a former member and leader of the Non-Aligned Movement, and still considers itself an advocate for developing countries.[123]
Under its interpretation of the One-China policy, China has made it a precondition to establishing diplomatic relations that the other country acknowledges its claim to Taiwan and severs official ties with the government of the Republic of China. Chinese officials have protested on numerous occasions when foreign countries have made diplomatic overtures to Taiwan,[124] especially in the matter of armament sales.[125] Political meetings between foreign government officials and the 14th Dalai Lama are also opposed by China, as it considers Tibet to be formally part of China.[126]
Much of China's current foreign policy is reportedly based on the Five Principles of Peaceful Coexistence of Zhou Enlai—non-interference in other states' affairs, non-aggression, peaceful coexistence, equality and mutual benefits. China's foreign policy is also driven by the concept of "harmony without uniformity", which encourages diplomatic relations between states despite ideological differences. This policy has led China to support states that are regarded as dangerous or repressive by Western nations, such as Zimbabwe, North Korea, and Iran.[127] Conflicts with foreign countries have occurred at times in China's recent history, particularly with the United States; for example, the US bombing of the Chinese embassy in Belgrade during the Kosovo conflict in May 1999 and the US-China spy plane incident in April 2001. China's foreign relations with many Western nations suffered for a time following the military crackdown on the Tiananmen Square protests of 1989, although in recent years China has improved its diplomatic links with the West.[128][129]
In recent decades, China has played an increasing role in calling for free trade areas and security pacts amongst its Asia-Pacific neighbors. In 2004, China proposed an entirely new East Asia Summit (EAS) framework as a forum for regional security issues, pointedly excluding the United States.[130] The EAS, which includes ASEAN Plus Three, India, Australia and New Zealand, held its inaugural summit in 2005. China is also a founding member of the Shanghai Cooperation Organisation (SCO), along with Russia and the Central Asian republics.
In 2000, the U.S. Congress approved "permanent normal trade relations" (PNTR) with China, allowing Chinese exports in at the same low tariffs as goods from most other countries.[131] Both Bill Clinton and George W. Bush asserted that free trade would gradually open China to democratic reform.[132] Bush was furthermore an advocate of China's entry into the World Trade Organization (WTO).[133] China has a significant trade surplus with the United States, its most important export market.[134] In the early 2010s, U.S. politicians argued that the Chinese yuan was significantly undervalued, giving China an unfair trade advantage.[135]
Sinophobic attitudes often target Chinese minorities and nationals living outside of China. Sometimes, such anti-Chinese attitudes turn violent, as occurred during the 13 May Incident in Malaysia in 1969 and the Jakarta riots of May 1998 in Indonesia, in which more than 2,000 people died.[136] In recent years, a number of anti-Chinese riots and incidents have also occurred in Africa and Oceania.[137][138] Anti-Chinese sentiment is often rooted in socio-economics.[139]
China has been involved in a number of international territorial disputes, mostly resulting from the legacy of unequal treaties imposed on China during the historical period of New Imperialism. Since the 1990s, China has been entering negotiations to resolve its disputed land borders, usually by offering concessions and accepting less than half of the disputed territory with each party. China's only remaining land border disputes are a disputed border with India and an undefined border with Bhutan. China is additionally involved in more minor multilateral disputes over the ownership of several small islands in the East and South China Seas.[140][141]
The relationship between China and Japan has been strained at times by Japan's refusal to acknowledge its wartime past to the satisfaction of China. Revisionist comments made by prominent Japanese officials and some Japanese history textbooks regarding the 1937 Nanjing Massacre have been a focus of particular controversy. Sino-Japanese relations warmed considerably after Shinzo Abe became the Prime Minister of Japan in September 2006, and a joint historical study conducted by China and Japan released a report in 2010 which pointed toward a new consensus on the issue of World War 2-era atrocities.[142] However, in the early 2010s, relations cooled once more, with Japan accusing China of withholding its reserves of valuable rare earth elements.[143]
China is heavily engaged, both politically and economically, with numerous nations in the developing world. Most notably, they have followed a policy of engaging with African nations for trade and bilateral co-operation.[144][145] Xinhua, China's official news agency, states that there are no less than 750,000 Chinese nationals working or living in Africa.[146] China has furthermore strengthened its ties with major South American economies, becoming the largest trading partner of Brazil and building strategic links with Argentina.[147][148] Along with Brazil, Russia, India and South Africa, China is a member of the BRICS group of emerging major economies, and hosted the group's third official summit at Sanya in Hainan Province in April 2011.[149]
China is regularly hailed as a potential new superpower, with certain commentators citing its rapid economic progress, growing military might, very large population, and increasing international influence as signs that it will play a prominent global role in the 21st century. Others, however, warn that economic bubbles and demographic imbalances could slow or even halt China's growth as the century progresses.[150][151][152][153][154]
The Chinese democracy movement, social activists, and some members of the Communist Party of China have all identified the need for social and political reform. While economic and social controls have been greatly relaxed in China since the 1970s, political freedom is still tightly restricted. The Constitution of the People's Republic of China states that the "fundamental rights" of citizens include freedom of speech, freedom of the press, the right to a fair trial, freedom of religion, universal suffrage, and property rights. However, in practice, these provisions do not afford significant protection against criminal prosecution by the State.[155][156][157]
As the Chinese economy expanded following Deng Xiaoping's 1978 reforms, tens of millions of rural Chinese who have moved to the cities[158] find themselves treated as second-class citizens by China's hukou household registration system, which controls state benefits.[159] Property rights are often poorly protected, and eminent domain land seizures have had a disproportionate effect on poorer peasants.[158] In 2003, the average Chinese farmer paid three times more taxes than the average urban dweller, despite having one-sixth of the annual income.[159] However, a number of rural taxes have since been reduced or abolished, and additional social services provided to rural dwellers.[160][161][162]
Censorship of political speech and information, most notably on the Internet,[163] is openly and routinely used in China to silence criticism of the government and the ruling Communist Party.[164][165] In 2005, Reporters Without Borders ranked China 159th out of 167 states in its Annual World Press Freedom Index, indicating a very low level of perceived press freedom.[166] The government has suppressed demonstrations by organizations that it considers a potential threat to "social stability", as was the case with the Tiananmen Square protests of 1989. The Communist Party has had mixed success in controlling information: a powerful and pervasive media control system faces equally strong market forces, an increasingly educated citizenry, and technological and cultural changes that are making China more open to the wider world, especially on environmental issues.[167][168] However, attempts are still made by the Chinese government to control public access to outside information, with online searches for politically sensitive material being blocked by the so-called Great Firewall.[169]
A number of foreign governments and NGOs routinely criticize China's human rights record, alleging widespread civil rights violations, including systematic use of lengthy detention without trial, forced confessions, torture, mistreatment of prisoners, and restrictions of freedom of speech, assembly, association, religion, the press, and labor rights.[110] China executes more people than any other country, accounting for 72% of the world's total in 2009, though it is not the largest executioner per capita.[170] This high execution rate is partly due to the fact that numerous white-collar crimes, such as fraud, are punishable by death in China. However, in the early 2010s, China began restricting the application of capital punishment for some such crimes.[171]
The Chinese government has responded to foreign criticism by arguing that the notion of human rights should take into account a country's present level of economic development, and focus more on the people's rights to subsistence and development in poorer countries.[172] The rise in the standard of living, literacy, and life expectancy for the average Chinese since the 1970s is seen by the government as tangible progress made in human rights.[173] Improvements in workplace safety, and efforts to combat natural disasters such as the perennial Yangtze River floods, are also portrayed in China as progress in human rights for a still largely poor country.[172][174]
Some Chinese politicians have spoken out in favor of reforms, while others remain more conservative. In 2010, Premier Wen Jiabao stated that China needs "to gradually improve the democratic election system so that state power will truly belong to the people and state power will be used to serve the people." Despite his status, Wen's comments were later censored by the government.[175]
As the social, cultural and political consequences of economic growth and reform become increasingly manifest, tensions between the conservatives and reformists in the Communist Party are sharpening. Zhou Tianyong, the vice director of research of the Central Party School, argues that gradual political reform as well as repression of those pushing for overly rapid change over the next thirty years will be essential if China is to avoid an overly turbulent transition to a democratic, middle-class-dominated polity.[176][177]
With 2.3 million active troops, the People's Liberation Army (PLA) is the largest standing military force in the world, commanded by the Central Military Commission (CMC).[178] The PLA consists of the People's Liberation Army Ground Force (PLAGF), the People's Liberation Army Navy (PLAN), the People's Liberation Army Air Force (PLAAF), and a strategic nuclear force, the Second Artillery Corps. According to SIPRI, China's military expenditure in 2011 totalled US$129.2 billion (923 billion yuan), constituting the world's second-largest military budget.[179] However, other nations, such as the United States, have claimed that China does not report its real level of military spending, which is allegedly much higher than the official budget.[180]
As a recognised nuclear weapons state, China is considered both a major regional military power and a potential military superpower.[181] As of August 2011, China's Second Artillery Corps is believed to maintain at least 195 nuclear missiles, including 75 ICBMs.[182] Nonetheless, China is the only member of the UN Security Council to have relatively limited power projection capabilities.[183] To offset this, it has begun developing power projection assets, such as aircraft carriers, and has established a network of foreign military relationships that has been compared to a string of pearls.
China has made significant progress in modernizing its military since the early 2000s. It has purchased advanced Russian fighter jets, such as the Sukhoi Su-30, and has also produced its own modern fighters, most notably the Chengdu J-10 and Shenyang J-11.[184] China is furthermore engaged in developing an indigenous stealth aircraft, the Chengdu J-20.[185][186][187] China's ground forces have also undergone significant modernisations, replacing its ageing Soviet-derived tank inventory with numerous variants of the modern Type 99 tank, and upgrading its battlefield C3I systems to enhance its network-centric warfare capabilities.[188] China has furthermore acquired and improved upon the Russian S-300 surface-to-air missile system.[189] Russia later produced the next-generation S-400 Triumf system, with China reportedly having spent $500 million on a downgraded export version of it.[190] A number of indigenous missile technologies have also been developed – in 2007, China conducted a successful test of an anti-satellite missile,[191] and its first indigenous land-attack cruise missile, the CJ-10, entered service in 2009. In 2011, the Pentagon reported that China was believed to be testing the JL-2 missile, a submarine-launched nuclear ICBM with multiple-warhead delivery capabilities.[182]
In recent years, much attention has been focused on enhancing the blue-water capabilities of the People's Liberation Army Navy.[192] In August 2011, China's first aircraft carrier, the refurbished Soviet vessel Varyag, began sea trials.[193] China furthermore maintains a substantial fleet of submarines, including several nuclear-powered attack and ballistic missile submarines.[194] On 13 March 2011, the PLAN missile frigate Xuzhou was spotted off the coast of Libya, marking the first time in history a Chinese warship sailed into the Mediterranean. The ship's entrance into the Mediterranean was officially part of a humanitarian mission to rescue Chinese nationals from the 2011 Libyan civil war, though analysts such as Fareed Zakaria viewed the mission as also being an attempt to increase China's global military presence.[195]
Little information is available regarding the motivations supporting China's military modernization. A 2007 report by the US Secretary of Defense noted that "China's actions in certain areas increasingly appear inconsistent with its declaratory policies".[196] For its part, China claims it maintains an army purely for defensive purposes.[197]
As of 2012, China has the world's second-largest economy in terms of nominal GDP, totalling approximately US$7.298 trillion according to the International Monetary Fund (IMF).[6] However, China's 2011 nominal GDP per capita of US$5,184 puts it behind around ninety countries (out of 183 countries on the IMF list) in global GDP per capita rankings.[6] If PPP is taken into account in total GDP figures, China is again second only to the United States—in 2011, its PPP GDP reached $11.316 trillion, corresponding to $8,394 per capita.[6] In 2009, China's primary, secondary, and tertiary industries contributed 10.6%, 46.8%, and 42.6% respectively to its total GDP.
From its founding in 1949 until late 1978, the People's Republic of China was a Soviet-style centrally planned economy, without private businesses or capitalism. To propel the country towards a modern, industrialized communist society, Mao Zedong instituted the Great Leap Forward in the early 1960s, although this had decidedly mixed economic results.[199] Following Mao's death in 1976 and the consequent end of the Cultural Revolution, Deng Xiaoping and the new Chinese leadership began to reform the economy and move towards a more market-oriented mixed economy under one-party rule. Collectivization of the agriculture was dismantled and farmlands were privatized to increase productivity. Modern-day China is mainly characterized as having a market economy based on private property ownership,[200][201] and is one of the leading examples of state capitalism.[202][203]
Under the post-Mao market reforms, a wide variety of small-scale private enterprises were encouraged, while the government relaxed price controls and promoted foreign investment. Foreign trade was focused upon as a major vehicle of growth, leading to the creation of Special Economic Zones (SEZs), first in Shenzhen and then in other Chinese cities. Inefficient state-owned enterprises (SOEs) were restructured by introducing western-style management systems, with unprofitable ones being closed outright, resulting in massive job losses. By the latter part of 2010, China was reversing some of its economic liberalization initiatives, with state-owned companies buying up independent businesses in the steel, auto and energy industries.[204]
Since economic liberalization began in 1978, China's investment- and export-led[205] economy has grown almost a hundredfold[206] and is the fastest-growing major economy in the world.[207] According to the IMF, China's annual average GDP growth between 2001 and 2010 was 10.5%, and the Chinese economy is predicted to grow at an average annual rate of 9.5% between 2011 and 2015. Between 2007 and 2011, China's economic growth rate was equivalent to all of the G7 countries' growth combined.[208] According to the Global Growth Generators index announced by Citigroup in February 2011, China has a very high 3G growth rating.[209]
China is the third-most-visited country in the world, with 55.7 million inbound international visitors in 2010.[210] It is a member of the WTO and is the world's second-largest trading power behind the US, with a total international trade value of US$3.64 trillion in 2011.[211] Its foreign exchange reserves reached US$2.85 trillion by the end of 2010, an increase of 18.7% over the previous year, making its reserves by far the world's largest.[212][213] China owns an estimated $1.6 trillion of US securities.[214] China, holding US$1.16 trillion in US Treasury bonds,[215] is the largest foreign holder of US public debt.[216][217] China is the world's third-largest recipient of inward foreign direct investment (FDI), attracting $115 billion in 2011 alone, marking a 9% increase over 2010.[218][219] China also increasingly invests abroad, with a total outward FDI of $68 billion in 2010.[220]

China's success has been primarily due to manufacturing as a low-cost producer. This is attributed to a combination of cheap labor, good infrastructure, relatively high productivity, favorable government policy, and a possibly undervalued exchange rate. The latter has been sometimes blamed for China's huge trade surplus (US$262.7 billion in 2007)[222] and has become a major source of dispute between China and its major trading partners—the US, EU, and Japan—despite the yuan having been de-pegged and having risen in value by 20% against the US dollar since 2005.[223] China is moreover widely criticised for manufacturing large quantities of counterfeit goods—in 2005, the Asia Business Council alleged that the counterfeiting industry accounted for 8% of China's GDP at the time.[224][225]
The state still dominates in strategic "pillar" industries (such as energy and heavy industries), but private enterprise (composed of around 30 million private businesses)[226] has expanded enormously; in 2005, it accounted for anywhere between 33%[227] to 70%[228] of national GDP, while the OECD estimate for that year was over 50%[229] of China's national output, up from 1% in 1978.[230] The Shanghai Stock Exchange has raised record amounts of IPOs, and its benchmark Shanghai Composite index has doubled since 2005. SSE's market capitalization reached US$3 trillion in 2007, making it the world's fifth-largest stock exchange.
China now ranks 29th in the Global Competitiveness Index,[231] although it is only ranked 135th among the 179 countries measured in the Index of Economic Freedom.[232] 46 Chinese companies made the list in the 2010 Fortune Global 500 (Beijing alone with 30).[233] Measured using market capitalization, four of the world's top ten most valuable companies are Chinese. Some of these include first-ranked PetroChina, third-ranked Industrial and Commercial Bank of China (the world's most valuable bank), fifth-ranked China Mobile (the world's most valuable telecommunications company) and seventh-ranked China Construction Bank.[234]
Although a middle-income country by Western standards, China's rapid growth has pulled hundreds of millions of its people out of poverty since 1978. Today, about 10% of the Chinese population live below the poverty line of US$1 per day (down from 64% in 1978), while life expectancy has increased to 73 years. More than 93% of the population is literate,[235] compared to only 20% in 1950.[236] Urban unemployment in China reportedly declined to 4% by the end of 2007, although true overall unemployment may be as high as 10%.[237]
China's middle-class population (defined as those with annual income of at least US$17,000) has reached more than 100 million as of 2011,[238] while the number of super-rich individuals worth more than 10 million yuan (US$1.5 million) is estimated to be 825,000, according to Hurun Report.[239] Based on the Hurun rich list, the number of US dollar billionaires in China doubled from 130 in 2009 to 271 in 2010, giving China the world's second-highest number of billionaires.[240] China's retail market was worth RMB 8.9 trillion (US$1.302 trillion) in 2007, and is growing at 16.8% annually.[241] China is also now the world's second-largest consumer of luxury goods behind Japan, with 27.5% of the global share.[242]
In recent years, China's rapid economic growth has contributed to severe consumer inflation,[243] causing the prices of basic goods to rise steeply. Food prices in China increased by over 21% in the first four months of 2008 alone.[244] To curb inflation and moderate rising property prices, the Chinese government has instituted a number of fiscal regulations and amendments, raising interest rates and imposing limits on bank loans. In September 2011, consumer prices rose by 6.1% compared to a year earlier, marking a reduction in inflation from the peak of 6.5% in July 2011.[245] A side-effect of increased economic regulation was a slowdown in overall growth – China's quarterly GDP growth fell to 9.1% in October 2011, down from 9.5% in the previous quarter,[245] and sank to 8.1% in April 2012.[246]
The Chinese economy is highly energy-intensive and inefficient—on average, industrial processes in China between 20% and 100% more energy than similar ones in OECD countries.[247] China became the world's largest energy consumer in 2010,[248] but still relies on coal to supply about 70% of its energy needs.[249] Coupled with lax environmental regulations, this has led to massive water and air pollution, leaving China with 20 of the world's 30 most polluted cities.[247] Consequently, the government has promised to use more renewable energy, planning to make renewables constitute 30% of China's total energy production by 2050.[250] In 2010, China became the largest wind energy provider in the world, with a total installed wind power capacity of 41.8 GW.[251] In January 2011, Russia began scheduled oil shipments to China, pumping 300,000 barrels of oil per day via the Eastern Siberia – Pacific Ocean oil pipeline.[252]

China was a world leader in science and technology until the Ming Dynasty. Ancient Chinese discoveries and inventions, such as papermaking, printing, the compass, and gunpowder (the Four Great Inventions), contributed to the economic development of Asia and Europe. However, Chinese scientific activity entered a prolonged decline in the fourteenth century. Unlike European scientists, medieval Chinese thinkers did not attempt to reduce observations of nature to mathematical laws, and they did not form a scholarly community offering peer review and progressive research. There was an increasing concentration on literature, the arts, and public administration, while science and technology were seen as trivial or restricted to limited practical applications.[253] The causes of this Great Divergence continue to be debated.
After repeated military defeats by Western nations in the 19th century, Chinese reformers began promoting modern science and technology as part of the Self-Strengthening Movement. After the Communist victory in 1949, efforts were made to organize science and technology based on the model of the Soviet Union. However, Mao Zedong's Cultural Revolution of 1966-76 had a catastrophic effect on Chinese research, as academics were persecuted and the training of scientists and engineers was severely curtailed for nearly a decade. After Mao's death in 1976, science and technology was established as one of the Four Modernizations, and the Soviet-inspired academic system was gradually reformed.[253]
In modern China, science and technology are seen as vital for achieving economic and political goals, and are held as a source of national pride to a degree sometimes described as "techno-nationalism".[254] Almost all of the members of the Politburo Standing Committee of the Communist Party of China have engineering degrees.[255] Since the end of the Cultural Revolution, China has become one of the world's leading technological powers, spending over US$100 billion on scientific research and development in 2011 alone.[256] China is also rapidly developing its education system with an emphasis on science, mathematics and engineering; in 2009, it produced over 10,000 Ph.D. engineering graduates, and as many as 500,000 BSc graduates, more than any other country.[257] China is also the world's second-largest publisher of scientific papers, producing 121,500 in 2010 alone, including 5,200 in leading international scientific journals.[258]
The Chinese space program is one of the world's most active, and is a major source of national pride.[259] In 1970, China launched its first satellite, Dong Fang Hong I. In 2003, China became the third country to independently send humans into space, with Yang Liwei's spaceflight aboard Shenzhou 5. In 2008, China conducted its first spacewalk with the Shenzhou 7 mission. In 2011, China's first space station module, Tiangong-1, was launched, marking the first step in a project to assemble a large manned station by 2020.[260] The active Chinese Lunar Exploration Program includes a planned lunar rover launch in 2013, and possibly a manned lunar landing in 2025.[261] Experience gained from the lunar program may be used for future programs such as the exploration of Mars and Venus.[262]
China currently has the most cellphone users of any country in the world, with over 1 billion users as of May 2012.[263][264] It also has the world's largest number of internet and broadband users.[265] By December 2010, China had around 457 million internet users, an increase of 19% over the previous year, and by the end of 2011 the number of internet users had exceeded 500 million.[266][267][268] According to the China Internet Network Information Center (CNNIC), China's average internet connection speed is 100.9 kbit/s, less than half of the global average of 212.5 kbit/s.[269]
China Telecom and China Unicom, the country's two largest broadband providers, accounted for 20% of global broadband subscribers, whereas the world's ten largest broadband service providers combined accounted for 39% of the world's broadband customers. China Telecom alone serves 55 million broadband subscribers, while China Unicom serves more than 40 million. The massive rise in internet use in China continues to fuel rapid broadband growth, whereas the world's other major broadband ISPs operate in the mature markets of the developed world, with high levels of broadband penetration and rapidly slowing subscriber growth.[270]
Transportation in mainland China has undergone intense state-led development since the late 1990s. The national road network has been significantly expanded through the creation of a network of expressways, known as the National Trunk Highway System (NTHS). By the end of 2011, China's expressways had reached a total length of 85,000 km (53,000 mi), second only to the network of the United States.[271] Private car ownership is growing rapidly in China, which surpassed the United States as the world's largest automobile market in 2009, with total car sales of over 13.6 million.[272] Analysts predict that annual car sales in China may rise as high as 40 million by 2020.[273]
China also possesses the world's longest high-speed rail network, with over 9,676 km (6,012 mi) of service routes. Of these, 3,515 km (2,184 mi) serve trains with top speeds of 300 km/h (190 mph).[274] In 2011, China unveiled a prototype train capable of reaching speeds of 310 mph (500 km/h), the first ultra-high-speed train developed solely by its domestic railway industry.[275] China intends to operate approximately 16,000 km (9,900 mi) of high-speed rail lines by 2020.[276]
As of 2012, China is the world's largest constructor of new airports, and the Chinese government has begun a US$250 billion five-year project to expand and modernize domestic air travel.[277] However, long-distance transportation remains dominated by railways and charter bus systems. Railways are the vital carrier in China; they are monopolized by the state, divided into various railway bureaux in different regions. Due to huge demand, the system is regularly subject to overcrowding, particularly during holiday seasons, such as Chunyun during the Chinese New Year. The Chinese rail network carried an estimated 1.68 billion total passengers in 2010 alone.[276]
Rapid transit systems are also rapidly developing in China's major cities, in the form of networks of underground or light rail systems. Hong Kong has one of the most developed transport systems in the world, while Shanghai has a high-speed maglev rail line connecting the city to its main international airport, Pudong International Airport. China is additionally developing its own satellite navigation system, dubbed Beidou, which began offering commercial navigation services in mainland China in 2011, and is planned to offer global coverage by 2020.[278]
As of July 2010, the People's Republic of China has an estimated total population of 1,338,612,968. About 21% of the population (145,461,833 males; 128,445,739 females) are 14 years old or younger, 71% (482,439,115 males; 455,960,489 females) are between 15 and 64 years old, and 8% (48,562,635 males; 53,103,902 females) are over 65 years old. The population growth rate for 2006 was 0.6%.[279]
By end of 2010, the proportion of mainland Chinese people aged 14 or younger was 16.60%, while the number aged 60 or older grew to 13.26%, giving a total proportion of 29.86% dependents. The proportion of the population of workable age was thus around 70%.[280]
With a population of over 1.3 billion and dwindling natural resources, China is very concerned about its population growth and has attempted, with mixed results,[281] to implement a strict family planning policy. The government's goal is one child per family, with exceptions for ethnic minorities and a degree of flexibility in rural areas. It is hoped that population growth in China will stabilize in the early decades of the 21st century, though some projections estimate a population of anywhere between 1.4 billion and 1.6 billion by 2025. China's family planning minister has indicated that the one-child policy will be maintained until at least 2020.[282]
The one-child policy is resisted, particularly in rural areas, because of the need for agricultural labour and a traditional preference for boys (who can later serve as male heirs). Families who breach the policy often lie during the census.[283] Official government policy opposes forced sterilization or abortion, but allegations of coercion continue as local officials, who are faced with penalties for failing to curb population growth, may resort to forcible measures, or manipulation of census figures.[citation needed]
The decreasing reliability of China population statistics since family planning began in the late 1970s has made evaluating the effectiveness of the policy difficult.[283] Data from the 2010 census implies that the total fertility rate may now be around 1.4.[284] The government is particularly concerned with the large imbalance in the sex ratio at birth, apparently the result of a combination of traditional preference for boys and family planning pressure, which led to a ban on using ultrasound devices in an attempt to prevent sex-selective abortion.
According to the 2010 census, there were 118.06 boys born for every 100 girls, which is 0.53 points lower than the ratio obtained from a population sample survey carried out in 2005.[285] However, the gender ratio of 118.06 is still beyond the normal range of around 105 percent, and experts warn of increased social instability should this trend continue.[286] For the population born between the years 1900 and 2000, it is estimated that there could be 35.59 million fewer females than males.[287] Other demographers argue that perceived gender imbalances may arise from the underreporting of female births.[288][289][290][291] A recent study suggests that as many as three million Chinese babies are hidden by their parents every year.[291] According to the 2010 census, males accounted for 51.27 percent of the total population, while females made up 48.73 percent of the total.[285]

China officially recognizes 56 distinct ethnic groups, the largest of which are the Han Chinese, who constitute about 91.51% of the total population.[293] The Han Chinese—the world's largest single ethnic group—outnumber other ethnic groups in every province, municipality and autonomous region except Tibet and Xinjiang, and are descended from ancient Huaxia tribes living along the Yellow River.
Ethnic minorities account for about 8.49% of the population of China, according to the 2010 census.[293] Compared with the 2000 population census, the Han population increased by 66,537,177 persons, or 5.74%, while the population of the 55 national minorities combined increased by 7,362,627 persons, or 6.92%.[293]
The 2010 census recorded a total of 593,832 foreign citizens living in China. The largest such groups were from South Korea (120,750), the United States (71,493) and Japan (66,159).[294]
The languages most spoken in China belong to the Sino-Tibetan language family. There are also several major linguistic groups within the Chinese language itself. The most spoken varieties are Mandarin (spoken by over 70% of the population), Wu (includes Shanghainese), Yue (includes Cantonese and Taishanese), Min (includes Hokkien and Teochew), Xiang, Gan, and Hakka. Non-Sinitic languages spoken widely by ethnic minorities include Zhuang, Mongolian, Tibetan, Uyghur, Hmong and Korean.[295] Standard Mandarin, a variety of Mandarin based on the Beijing dialect, is the official national language of China and is used as a lingua franca between people of different linguistic backgrounds.
Classical Chinese was the written standard in China for thousands of years, and allowed for written communication between speakers of various unintelligible languages and dialects in China. Written vernacular Chinese, or baihua, is the written standard, based on the Mandarin dialect and first popularized in Ming Dynasty novels. It was adopted, with significant modifications, during the early 20th century as the national standard. Classical Chinese is still part of the high school curriculum, and is thus intelligible to some degree to many Chinese. Since their promulgation by the government in 1956, Simplified Chinese characters have become the official standardized written script used to write the Chinese language within mainland China, supplanting the use of the earlier Traditional Chinese characters.
Since 2000, China's cities have expanded at an average rate of 10% annually. It is estimated that China will add 400 million people to its urban population by 2025.[296] The country's urbanization rate increased from 17.4% to 46.8% between 1978 and 2009, a scale unprecedented in human history.[297] Between 150 and 200 million migrant workers work part-time in the major cities, returning home to the countryside periodically with their earnings.[298][299]
Today, the People's Republic of China has dozens of cities with one million or more long-term residents, including the three global cities of Beijing, Hong Kong, and Shanghai. The figures in the table below are from the 2008 census, and are only estimates of the urban populations within administrative city limits; a different ranking exists when considering the total municipal populations (which includes suburban and rural populations). The large "floating populations" of migrant workers make conducting censuses in urban areas difficult;[300] the figures below do not include the floating population, only long-term residents.

In 1986, China set the long-term goal of providing compulsory nine-year basic education to every child. As of 2007, there were 396,567 primary schools, 94,116 secondary schools, and 2,236 higher education institutions in China.[301] In February 2006, the government advanced its basic education goal by pledging to provide completely free nine-year education, including textbooks and fees.[302] Free compulsory education in China consists of elementary school and middle school, which lasts for 9 years (ages 6–15); almost all children in urban areas continue with three years of high school.
As of 2007[update], 93.3% of the population over age 15 are literate.[279] In 2000, China's literacy rate among 15-to-24-year-olds was 98.9% (99.2% for males and 98.5% for females).[303] In March 2007, the Chinese government declared education a national "strategic priority"; the central budget for national scholarships was tripled between 2007 and 2009, and 223.5 billion yuan (US$28.65 billion) of extra state funding was allocated between 2007 and 2012 to improve compulsory education in rural areas.[304]
In 2009, Chinese students from Shanghai achieved the world's best results in mathematics, science and literacy, as tested by the Programme for International Student Assessment (PISA), a worldwide evaluation of 15-year-old school pupils' scholastic performance.[305]
The quality of Chinese colleges and universities varies considerably across the country. The consistently top-ranked universities in mainland China are:[306][307]
The Ministry of Health, together with its counterparts in the provincial health bureaux, oversees the health needs of the Chinese population.[308] An emphasis on public health and preventive medicine has characterized health policy since the early 1950s. At that time, the Communist Party started the Patriotic Health Campaign, which was aimed at improving sanitation and hygiene, as well as treating and preventing several diseases. Diseases such as cholera, typhoid and scarlet fever, which were previously rife in China, were nearly eradicated by the campaign.
After Deng Xiaoping began instituting economic reforms in 1978, the health of the Chinese public improved rapidly due to better nutrition, although many of the free public health services provided in the countryside disappeared along with the People's Communes. Healthcare in China became mostly privatised, and experienced a significant rise in quality. The national life expectancy at birth rose from about 35 years in 1949 to 73.18 years in 2008,[309][310] and infant mortality decreased from 300 per thousand in the 1950s to around 23 per thousand in 2006.[39][311] Malnutrition as of 2002[update] stood at 12% of the population, according to United Nations FAO sources.[312] In 2009, the government began a large-scale healthcare provision initiative worth US$124 billion, which is expected to eventually cover 90% of China's population.[313]
Despite significant improvements in health and the construction of advanced medical facilities, China has several emerging public health problems, such as respiratory illnesses caused by widespread air pollution[314] and hundreds of millions of cigarette smokers,[315][316] a possible future HIV/AIDS epidemic, and an increase in obesity among urban youths.[317][318] China's large population and densely populated cities have led to serious disease outbreaks in recent years, such as the 2003 outbreak of SARS, although this has since been largely contained.[319]
Estimates of excess deaths in China from environmental pollution (apart from smoking) are placed at 760,000 people per annum from air and water pollution (including indoor air pollution).[320] In 2007, China overtook the United States as the world's biggest producer of carbon dioxide.[321] Some 90% of China's cities suffer from some degree of water pollution,[322] and nearly 500 million people lacked access to safe drinking water in 2005.[323] Reports by the World Bank and the New York Times have claimed industrial pollution, particularly of the air, to be a significant health hazard in China.[324]
In mainland China, the government allows a degree of religious freedom to members of state-approved religious organizations. An accurate number of religious adherents is hard to obtain because of a lack of official data, but there is a general consensus that religion has been enjoying a resurgence in China since the late 1980s.[325] A 1998 survey by Adherents.com found that 59% (over 700 million) of the population was irreligious.[326] A later survey, conducted in 2007, found that there were 300 million religious believers in China, constituting 23% of the population, as distinct from an official figure of 100 million.[325]
Despite the surveys' varying results, most agree that China's traditional religions—Buddhism, Taoism, and Chinese folk religions—are the dominant faiths. According to various sources, Buddhism in China accounts for between 660 million (~50% of the population) and over 1 billion (~80%),[327][328][329][330] while Taoists number as many as 400 million (~30%).[331][332] However, because of the fact that one person may subscribe to two or more of these traditional beliefs simultaneously, and the difficulty in clearly differentiating Buddhism, Taoism, and Chinese folk religions, there is likely a strong degree of overlap in the number of adherents of these religions. In addition, some who subscribe to Buddhism and Taoism follow their philosophies in principle but stop short of believing in any kind of deity or divinity.[333][334][335]
Most Chinese Buddhists are merely nominal adherents, because only a small proportion of the population (around 8% or 100 million)[337][338] may have taken the formal step of going for refuge.[339][340] Even then, it is still difficult to estimate accurately the number of Buddhists, because they do not have congregational memberships and often do not participate in public ceremonies.[341] Mahayana Buddhism (大乘, Dacheng) and its subsets Pure Land (Amidism), Tiantai and Chán (better known in English by its Japanese pronunciation Zen) are the most widely practiced denominations of Buddhism. Other forms, such as Theravada and Tibetan Buddhism, are practiced largely by ethnic minorities along the geographic fringes of the Chinese mainland.[342]
Christianity was first introduced to China during the Tang Dynasty, with the arrival of Nestorian Christianity in 635 AD. This was followed by Franciscan missionaries in the 13th century, Jesuits in the 16th century, and finally Protestants in the 19th century. Of China's minority religions, Christianity is one of the fastest-growing. The total number of Christians is difficult to determine, as many belong to unauthorized house churches, but estimates of their number have ranged from 40 million (3% of the total population)[325][343] to 54 million (4%)[344] to as many as 130 million (10%).[345] Official government statistics put the number of Christians at 25 million, but these count only members of officially sanctioned church bodies.[346] China is believed to now have the world's second-largest evangelical Christian population—behind only the United States—and is also experiencing a surge in mainstream Christian publishing.[347][348] In 2011, it was reported that more people attended Sunday church services in China than in all of Europe.[346]
Islam in China dates to a mission in 651, only 18 years after the death of the Prophet Muhammad. Muslims initially came to China for trade, becoming prominent in the trading ports of the Song Dynasty.[349][350] Later, Muslims such as Zheng He, Lan Yu and Yeheidie'erding became influential in government circles, and Nanjing became an important center of Islamic study.[351] Accurate statistics on China's Muslim population are hard to find; most estimates give a figure of between 20 and 30 million Muslims (1.5% to 2% of the total population).[352][353][354][355][356]
China also plays host to numerous minority religions, including Hinduism, Dongbaism, Bön, and a number of more modern religions and sects (particularly Xiantianism). In July 1999, the Falun Gong spiritual practice was officially banned by the authorities,[357] and many international organizations have criticized the government's treatment of Falun Gong that has occurred since then.[358] There are no reliable estimates of the number of Falun Gong practitioners in China,[359] although informal estimates have given figures as high as 70 million.[360][361]
Since ancient times, Chinese culture has been heavily influenced by Confucianism and conservative philosophies. For centuries, opportunities for social advancement could be provided by high performance in the prestigious Imperial examinations, which were instituted in 605 AD to help the Emperor select skilful bureaucrats. The literary emphasis of the exams affected the general perception of cultural refinement in China, such as the belief that calligraphy and literati painting were higher forms of art than dancing or drama.
A number of more authoritarian and rational strains of thought were also influential, with Legalism being a prominent example. There was often conflict between the philosophies – for instance, the individualistic Song Dynasty neo-Confucians believed that Legalism departed from the original spirit of Confucianism. Examinations and a culture of merit remain greatly valued in China today. In recent years, a number of New Confucians have claimed that modern democratic ideals and human rights are compatible with traditional Confucian values.[363]
The first leaders of the People's Republic of China were born into the traditional imperial order, but were influenced by the May Fourth Movement and reformist ideals. They sought to change some traditional aspects of Chinese culture, such as rural land tenure, sexism, and the Confucian system of education, while preserving others, such as the family structure and culture of obedience to the state.
Some observers see the period following the establishment of the PRC in 1949 as a continuation of traditional Chinese dynastic history, while others claim that the Communist Party's rule has damaged the foundations of Chinese culture, especially through political movements such as the Cultural Revolution of the 1960s, where many aspects of traditional culture were destroyed, having been denounced as 'regressive and harmful' or 'vestiges of feudalism'. Many important aspects of traditional Chinese morals and culture, such as Confucianism, Chinese art, literature, and performing arts like Peking opera, were altered to conform to government policies and propaganda at the time.
Today, the Chinese government has accepted numerous elements of traditional Chinese culture as being integral to Chinese society. With the rise of Chinese nationalism and the end of the Cultural Revolution, various forms of traditional Chinese art, literature, music, film, fashion and architecture have seen a vigorous revival,[364][365] and folk and variety art in particular have sparked interest nationally and even worldwide.[366]
Prior to the beginning of maritime Sino-European trade in the 16th century, medieval China and the European West were linked by the Silk Road, which was a key route of cultural as well as economic exchange. Artifacts from the history of the Road, as well as from the natural history of the Gobi desert, are displayed in the Silk Route Museum in Jiuquan.[367]

Chinese cuisine is highly diverse, drawing on several millennia of culinary history. The dynastic emperors of ancient China were known to host banquets with over 100 dishes served at a time,[368] employing countless imperial kitchen staff and concubines to prepare the food. Such royal dishes gradually became a part of wider Chinese culture. China's staple food is rice, but the country is also well known for its meat dishes. Spices are endemic to Chinese cuisine.
Numerous foreign offshoots of Chinese food, such as Hong Kong cuisine and American Chinese food, have emerged in the various nations which play host to the Chinese diaspora.
China has one of the oldest sporting cultures in the world. There is evidence that a form of association football was played in China around 1000 AD.[369] Today, some of the most popular sports in the country include martial arts, basketball, football, table tennis, badminton, swimming and snooker. Board games such as go (weiqi), xiangqi, and more recently chess, are also played at a professional level.[370]
Physical fitness is widely emphasized in Chinese culture. Morning exercises are a common activity, with elderly citizens encouraged to practice qigong and t'ai chi ch'uan. Young people in China are also keen on basketball, especially in urban centers with limited space and grass areas. The American National Basketball Association has a huge following among Chinese youths, with Chinese players such as Yao Ming being held in high esteem.[371]
Many more traditional sports are also played in China. Dragon boat racing occurs during the annual nationwide Dragon Boat Festival, and has since gained popularity abroad. In Inner Mongolia, sports such as Mongolian-style wrestling and horse racing are popular. In Tibet, archery and equestrianism are a part of traditional festivals.[372]
China has participated at the Olympic Games since 1932, although it has only participated as the PRC since 1952. China hosted the 2008 Summer Olympics in Beijing, and received 51 gold medals – the highest number of gold medals of any participating nation that year.[373] China will host the 2013 East Asian Games in Tianjin and the 2014 Youth Olympic Games in Nanjing.

In computational linguistics, word-sense disambiguation (WSD) is an open problem of natural language processing, which governs the process of identifying which sense of a word (i.e. meaning) is used in a sentence, when the word has multiple meanings (polysemy). The solution to this problem impacts other computer-related writing, such as discourse, improving relevance of search engines, anaphora resolution, coherence, inference et cetera.
Research has progressed steadily to the point where WSD systems achieve sufficiently high levels of accuracy on a variety of word types and ambiguities. A rich variety of techniques have been researched, from dictionary-based methods that use the knowledge encoded in lexical resources, to supervised machine learning methods in which a classifier is trained for each distinct word on a corpus of manually sense-annotated examples, to completely unsupervised methods that cluster occurrences of words, thereby inducing word senses. Among these, supervised learning approaches have been the most successful algorithms to date.
Current accuracy is difficult to state without a host of caveats. In English, accuracy at the coarse-grained (homograph) level is routinely above 90%, with some methods on particular homographs achieving over 96%. On finer-grained sense distinctions, top accuracies from 59.1% to 69.0% have been reported in recent evaluation exercises (SemEval-2007, Senseval-2), where the baseline accuracy of the simplest possible algorithm of always choosing the most frequent sense was 51.4% and 57%, respectively.

A disambiguation process requires two strict things: a dictionary to specify the senses which are to be disambiguated and a corpus of language data to be disambiguated (in some methods, a training corpus of language examples is also required). WSD task has two variants: "lexical sample" and "all words" task. The former comprises disambiguating the occurrences of a small sample of target words which were previously selected, while in the latter all the words in a piece of running text need to be disambiguated. The latter is deemed a more realistic form of evaluation, but the corpus is more expensive to produce because human annotators have to read the definitions for each word in the sequence every time they need to make a tagging judgement, rather than once for a block of instances for the same target word.
To give a hint how all this works, consider two examples of the distinct senses that exist for the (written) word "bass":
and the sentences:
To a human, it is obvious that the first sentence is using the word "bass (fish)", as in the former sense above and in the second sentence, the word "bass (instrument)" is being used as in the latter sense below. Developing algorithms to replicate this human ability can often be a difficult task, as is further exemplified by the implicit equivocation between "bass (sound)" and "bass" (musical instrument).
WSD was first formulated as a distinct computational task during the early days of machine translation in the 1940s, making it one of the oldest problems in computational linguistics. Warren Weaver, in his famous 1949 memorandum on translation,[1] first introduced the problem in a computational context. Early researchers understood the significance and difficulty of WSD well. In fact, Bar-Hillel (1960) used the above example to argue[2] that WSD could not be solved by "electronic computer" because of the need in general to model all world knowledge.
In the 1970s, WSD was a subtask of semantic interpretation systems developed within the field of artificial intelligence, but since WSD systems were largely rule-based and hand-coded they were prone to a knowledge acquisition bottleneck.
By the 1980s large-scale lexical resources, such as the Oxford Advanced Learner's Dictionary of Current English (OALD), became available: hand-coding was replaced with knowledge automatically extracted from these resources, but disambiguation was still knowledge-based or dictionary-based.
In the 1990s, the statistical revolution swept through computational linguistics, and WSD became a paradigm problem on which to apply supervised machine learning techniques.
The 2000s saw supervised techniques reach a plateau in accuracy, and so attention has shifted to coarser-grained senses, domain adaptation, semi-supervised and unsupervised corpus-based systems, combinations of different methods, and the return of knowledge-based systems via graph-based methods. Still, supervised systems continue to perform best.
One problem with word sense disambiguation is deciding what the senses are. In cases like the word bass above, at least some senses are obviously different. In other cases, however, the different senses can be closely related (one meaning being a metaphorical or metonymic extension of another), and in such cases division of words into senses becomes much more difficult. Different dictionaries and thesauruses will provide different divisions of words into senses. One solution some researchers have used is to choose a particular dictionary, and just use its set of senses. Generally, however, research results using broad distinctions in senses have been much better than those using narrow ones.[3][4] However, given the lack of a full-fledged coarse-grained sense inventory, most researchers continue to work on fine-grained WSD.
Most research in the field of WSD is performed by using WordNet as a reference sense inventory for English. WordNet is a computational lexicon that encodes concepts as synonym sets (e.g. the concept of car is encoded as { car, auto, automobile, machine, motorcar }). Other resources used for disambiguation purposes include Roget's Thesaurus[5] and Wikipedia.[6]
In any real test, part-of-speech tagging and sense tagging are very closely related with each potentially making constraints to the other. And the question whether these tasks should be kept together or decoupled is still not unanimously resolved, but recently scientists incline to test these things separately (e.g. in the Senseval/SemEval competitions parts of speech are provided as input for the text to disambiguate).
It is instructive to compare the word sense disambiguation problem with the problem of part-of-speech tagging. Both involve disambiguating or tagging with words, be it with senses or parts of speech. However, algorithms used for one do not tend to work well for the other, mainly because the part of speech of a word is primarily determined by the immediately adjacent one to three words, whereas the sense of a word may be determined by words further away. The success rate for part-of-speech tagging algorithms is at present much higher than that for WSD, state-of-the art being around 95% accuracy or better, as compared to less than 75% accuracy in word sense disambiguation with supervised learning. These figures are typical for English, and may be very different from those for other languages.
Another problem is inter-judge variance. WSD systems are normally tested by having their results on a task compared against those of a human. However, while it is relatively easy to assign parts of speech to text, training people to tag senses is far more difficult.[7] While users can memorize all of the possible parts of speech a word can take, it is often impossible for individuals to memorize all of the senses a word can take. Moreover, humans do not agree on the task at hand – give a list of senses and sentences, and humans will not always agree on which word belongs in which sense.[8]
Thus, a computer cannot be expected to give better performance on such a task than a human (indeed, since the human serves as the standard, the computer being better than the human is incoherent),[citation needed] so the human performance serves as an upper bound. Human performance, however, is much better on coarse-grained than fine-grained distinctions, so this again is why research on coarse-grained distinctions[9][10] has been put to test in recent WSD evaluation exercises.[3][4]
Some AI researchers like Douglas Lenat argue that one cannot parse meanings from words without some form of common sense ontology. For example, comparing these two sentences:
To properly identify senses of words one must know common sense facts.[11] Moreover, sometimes the common sense is needed to disambiguate such words like pronouns in case of having anaphoras or cataphoras in the text.
A task-independent sense inventory is not a coherent concept[12]: each task requires its own division of word meaning into senses relevant to the task. For example, the ambiguity of 'mouse' (animal or device) is not relevant in English-French machine translation, but is relevant in information retrieval. The opposite is true of 'river', which requires a choice in French (fleuve 'flows into the sea', or rivière 'flows into a river').
Also, completely different algorithms might be required by different applications. In machine translation, the problem takes the form of target word selection. Here, the "senses" are words in the target language, which often correspond to significant meaning distinctions in the source language ("bank" could translate to the French "banque" -- that is, 'financial bank' or "rive" -- that is, 'edge of river'). In information retrieval, a sense inventory is not necessarily required, because it is enough to know that a word is used in the same sense in the query and a retrieved document; what sense that is, is unimportant.
Finally, the very notion of "word sense" is slippery and controversial. Most people can agree in distinctions at the coarse-grained homograph level (e.g., pen as writing instrument or enclosure), but go down one level to fine-grained polysemy, and disagreements arise. For example, in Senseval-2, which used fine-grained sense distinctions, human annotators agreed in only 85% of word occurrences.[13] Word meaning is in principle infinitely variable and context sensitive. It does not divide up easily into distinct or discrete sub-meanings.[14] Lexicographers frequently discover in corpora loose and overlapping word meanings, and standard or conventional meanings extended, modulated, and exploited in a bewildering variety of ways. The art of lexicography is to generalize from the corpus to definitions that evoke and explain the full range of meaning of a word, making it seem like words are well-behaved semantically. However, it is not at all clear if these same meaning distinctions are applicable in computational applications, as the decisions of lexicographers are usually driven by other considerations. Recently, a task – named lexical substitution – has been proposed as a possible solution to the sense discreteness problem.[15] The task consists of providing a substitute for a word in context that preserves the meaning of the original word (potentially, substitutes can be chosen from the full lexicon of the target language, thus overcoming discreteness).
As in all natural language processing, there are two main approaches to WSD – deep approaches and shallow approaches.
Deep approaches presume access to a comprehensive body of world knowledge. Knowledge, such as "you can go fishing for a type of fish, but not for low frequency sounds" and "songs have low frequency sounds as parts, but not types of fish", is then used to determine in which sense the word is used. These approaches are not very successful in practice, mainly because such a body of knowledge does not exist in a computer-readable format, outside of very limited domains.[16] However, if such knowledge did exist, then deep approaches would be much more accurate than the shallow approaches.[citation needed] Also, there is a long tradition in computational linguistics, of trying such approaches in terms of coded knowledge and in some cases, it is hard to say clearly whether the knowledge involved is linguistic or world knowledge. The first attempt was that by Margaret Masterman and her colleagues, at the Cambridge Language Research Unit in England, in the 1950s. This attempt used as data a punched-card version of Roget's Thesaurus and its numbered "heads", as an indicator of topics and looked for repetitions in text, using a set intersection algorithm. It was not very successful,[17] but had strong relationships to later work, especially Yarowsky's machine learning optimisation of a thesaurus method in the 1990s.
Shallow approaches don't try to understand the text. They just consider the surrounding words, using information such as "if bass has words sea or fishing nearby, it probably is in the fish sense; if bass has the words music or song nearby, it is probably in the music sense." These rules can be automatically derived by the computer, using a training corpus of words tagged with their word senses. This approach, while theoretically not as powerful as deep approaches, gives superior results in practice, due to the computer's limited world knowledge. However, it can be confused by sentences like The dogs bark at the tree which contains the word bark near both tree and dogs.
There are four conventional approaches to WSD:
Almost all these approaches normally work by defining a window of n content words around each word to be disambiguated in the corpus, and statistically analyzing those n surrounding words. Two shallow approaches used to train and then disambiguate are Naïve Bayes classifiers and decision trees. In recent research, kernel-based methods such as support vector machines have shown superior performance in supervised learning. Graph-based approaches have also gained much attention from the research community, and currently achieve performance close to the state of the art.
The Lesk algorithm[18] is the seminal dictionary-based method. It is based on the hypothesis that words used together in text are related to each other and that the relation can be observed in the definitions of the words and their senses. Two (or more) words are disambiguated by finding the pair of dictionary senses with the greatest word overlap in their dictionary definitions. For example, when disambiguating the words in "pine cone", the definitions of the appropriate senses both include the words evergreen and tree (at least in one dictionary).
An alternative to the use of the definitions is to consider general word-sense relatedness and to compute the semantic similarity of each pair of word senses based on a given lexical knowledge base such as WordNet. Graph-based methods reminiscent of spreading activation research of the early days of AI research have been applied with some success. More complex graph-based approaches have been shown to perform almost as well as supervised methods[19] or even outperforming them on specific domains.[3][20] Recently, it has been reported that simple graph connectivity measures, such as degree, perform state-of-the-art WSD in the presence of a sufficiently rich lexical knowledge base.[21] Also, automatically transferring knowledge in the form of semantic relations from Wikipedia to WordNet has been shown to boost simple knowledge-based methods, enabling them to rival the best supervised systems and even outperform them in a domain-specific setting.[22]
The use of selectional preferences (or selectional restrictions) is also useful, for example, knowing that one typically cooks food, one can disambiguate the word bass in "I am cooking basses" (i.e., it's not a musical instrument).
Supervised methods are based on the assumption that the context can provide enough evidence on its own to disambiguate words (hence, world knowledge and reasoning are deemed unnecessary). Probably every machine learning algorithm going has been applied to WSD, including associated techniques such as feature selection, parameter optimization, and ensemble learning. Support Vector Machines and memory-based learning have been shown to be the most successful approaches, to date, probably because they can cope with the high-dimensionality of the feature space. However, these supervised methods are subject to a new knowledge acquisition bottleneck since they rely on substantial amounts of manually sense-tagged corpora for training, which are laborious and expensive to create.
Because of the lack of training data, many word sense disambiguation algorithms use semi-supervised learning, which allows both labeled and unlabeled data. The Yarowsky algorithm was an early example of such an algorithm.[23] It uses the ‘One sense per collocation’ and the ‘One sense per discourse’ properties of human languages for word sense disambiguation. From observation, words tend to exhibit only one sense in most given discourse and in a given collocation.
The bootstrapping approach starts from a small amount of seed data for each word: either manually tagged training examples or a small number of surefire decision rules (e.g., 'play' in the context of 'bass' almost always indicates the musical instrument). The seeds are used to train an initial classifier, using any supervised method. This classifier is then used on the untagged portion of the corpus to extract a larger training set, in which only the most confident classifications are included. The process repeats, each new classifier being trained on a successively larger training corpus, until the whole corpus is consumed, or until a given maximum number of iterations is reached.
Other semi-supervised techniques use large quantities of untagged corpora to provide co-occurrence information that supplements the tagged corpora. These techniques have the potential to help in the adaptation of supervised models to different domains.
Also, an ambiguous word in one language is often translated into different words in a second language depending on the sense of the word. Word-aligned bilingual corpora have been used to infer cross-lingual sense distinctions, a kind of semi-supervised system.
Unsupervised learning is the greatest challenge for WSD researchers. The underlying assumption is that similar senses occur in similar contexts, and thus senses can be induced from text by clustering word occurrences using some measure of similarity of context,[24] a task referred to as word sense induction or discrimination. Then, new occurrences of the word can be classified into the closest induced clusters/senses. Performance has been lower than other methods, above, but comparisons are difficult since senses induced must be mapped to a known dictionary of word senses. If a mapping to a set of dictionary senses is not desired, cluster-based evaluations (including measures of entropy and purity) can be performed. Alternatively, word sense induction methods can be tested and compared within an application. For instance, it has been shown that word sense induction improves Web search result clustering by increasing the quality of result clusters and the degree diversification of result lists.[25] It is hoped that unsupervised learning will overcome the knowledge acquisition bottleneck because they are not dependent on manual effort.
Other approaches may vary differently in their methods:
The knowledge acquisition bottleneck is perhaps the major impediment to solving the WSD problem. Unsupervised methods rely on knowledge about word senses, which is barely formulated in dictionaries and lexical databases. Supervised methods depend crucially on the existence of manually annotated examples for every word sense, a requisite that can so far be met only for a handful of words for testing purposes, as it is done in the Senseval exercises.
Therefore, one of the most promising trends in WSD research is using the largest corpus ever accessible, the World Wide Web, to acquire lexical information automatically.[33] WSD has been traditionally understood as an intermediate language engineering technology which could improve applications such as information retrieval (IR). In this case, however, the reverse is also true: Web search engines implement simple and robust IR techniques that can be successfully used when mining the Web for information to be employed in WSD. Therefore, the lack of training data provoked appearing some new algorithms and techniques described here:
Knowledge is a fundamental component of WSD. Knowledge sources provide data which are essential to associate senses with words. They can vary from corpora of texts, either unlabeled or annotated with word senses, to machine-readable dictionaries, thesauri, glossaries, ontologies, etc. They can be[34][35] classified as follows:
Comparing and evaluating different WSD systems is extremely difficult, because of the different test sets, sense inventories, and knowledge resources adopted. Before the organization of specific evaluation campaigns most systems were assessed on in-house, often small-scale, data sets. In order to test one's algorithm, developers should spend their time to annotate all word occurrences. And comparing methods even on the same corpus is not eligible if there is different sense inventories.
In order to define common evaluation datasets and procedures, public evaluation campaigns have been organized. Senseval (now renamed SemEval) is an international word sense disambiguation competition, held every three years since 1998: Senseval-1 (1998), Senseval-2 (2001), Senseval-3 (2004), and its successor, SemEval (2007). The objective of the competition is to organize different lectures, preparing and hand-annotating corpus for testing systems, perform a comparative evaluation of WSD systems in several kinds of tasks, including all-words and lexical sample WSD for different languages, and, more recently, new tasks such as semantic role labeling, gloss WSD, lexical substitution, etc. The systems submitted for evaluation to these competitions usually integrate different techniques and often combine supervised and knowledge-based methods (especially for avoiding bad performance in lack of training examples).
Sense Inventories. During the first Senseval workshop the HECTOR sense inventory was adopted. The reason for adopting a previously unknown sense inventory was mainly to avoid the use of popular fine-grained word senses (such as WordNet), which could make the experiments unfair or biased. However, given the lack of coverage of such inventories, since the second Senseval workshop the WordNet sense inventory has been adopted.
A set of testing words. Comparison of methods can be divided in 2 groups by amount of words to test. The difference consists in the amount of analysis and processing:
It is assumed that the former one is more realistic evaluation, although with very laborious testing of results. Initially only the latter was used in evaluation but later the former was included.
Lexical sample organizers had to choose samples on which the systems were to be tested. A criticism of earlier forays into lexical-sample WSD evaluation is that the lexical sample had been chosen according to the whim of the experimenter (or, to coincide with earlier experimenters' selections). For English Senseval, a sampling frame was devised in which words were classified according to their frequency (in the BNC) and their polysemy level (in WordNet). Also, inclusion POS-tagging problem was a matter of discussion and it was decided that samples should be words with known part of speech and some indeterminants (for ex. 15 noun tasks, 13 verb tasks, 8 adjectives, and 5 indeterminates).
Baselines. For comparison purposes, known, yet simple, algorithms named baselines are used. These include different variants of Lesk algorithm or most frequent sense algorithm.
Sense inventory. WSD exercises require a dictionary, to specify the word senses which are to be disambiguated, and a corpus of language data to be disambiguated. WordNet is the most popular example of sense inventory. The reason for adopting the HECTOR database during Senseval-1 was that the WordNet inventory was already publicly available.[37]
Evaluation measures. During the evaluation of WSD systems two main performance measures are used:
If a system makes an assignment for every word, then precision and recall are the same, and can be called accuracy. This model has been extended to take into account systems that return a set of senses with weights for each occurrence.
