Gray wolf

The gray wolf or grey wolf (Canis lupus), also known as the timber wolf or western wolf, is a canid native to the wilderness and remote areas of North America and Eurasia. It is the largest extant member of its family, with males averaging 43–45 kg (95–99 lb), and females 36–38.5 kg (79–85 lb). Like the red wolf, it is distinguished from other Canis species by its larger size and less pointed features, particularly on the ears and muzzle. Its winter fur is long and bushy, and predominantly a mottled gray in color, although nearly pure white, red, or brown to black also occur.As of 2005, 37 subspecies of C. lupus are recognised by MSW3.

The gray wolf is the second most specialised member of the genus Canis, after the Ethiopian wolf, as demonstrated by its morphological adaptations to hunting large prey, its more gregarious nature, and its highly advanced expressive behavior. It is nonetheless closely related enough to smaller Canis species, such as the eastern wolf,coyote and golden jackal to produce fertile hybrids. Its closest relative is the domestic dog, with which it shared a common European ancestor which likely diverged 40,000 years ago. It is the only species of Canis to have a range encompassing both the Old and New Worlds, and originated in Eurasia during the Pleistocene, colonizing North America on at least three separate occasions during the Rancholabrean. It is a social animal, travelling in nuclear families consisting of a mated pair, accompanied by the pair's adult offspring. The gray wolf is typically an apex predator throughout its range, with only humans and tigers posing a serious threat to it. It feeds primarily on large ungulates, though it also eats smaller animals, livestock, carrion, and garbage.

Word-sense disambiguation

In computational linguistics, word-sense disambiguation (WSD) is an open problem of natural language processing and ontology. WSD is identifying which sense of a word (i.e. meaning) is used in a sentence, when the word has multiple meanings. The solution to this problem impacts other computer-related writing, such as discourse, improving relevance of search engines, anaphora resolution, coherence, inference et cetera.

The human brain is quite proficient at word-sense disambiguation. The fact that natural language is formed in a way that requires so much of it is a reflection of that neurologic reality. In other words, human language developed in a way that reflects (and also has helped to shape) the innate ability provided by the brain's neural networks. In computer science and the information technology that it enables, it has been a long-term challenge to develop the ability in computers to do natural language processing and machine learning.

To date, 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.

National Geographic Society

The National Geographic Society (NGS), headquartered in Washington, D.C., United States, is one of the largest nonprofit scientific and educational institutions in the world. Its interests include geography, archaeology and natural science, the promotion of environmental and historical conservation, and the study of world culture and history. The National Geographic Society’s logo is a yellow portrait frame – rectangular in shape – which appears on the margins surrounding the front covers of its magazines and as its television channel logo. It also operates a website that features extra content and worldwide events.

A significant change was announced by National Geographic Society and 21st Century Fox on September 9, 2015. The two organizations revealed an "expanded joint venture" that would re-organize the Society's media properties and publications into a new company known as National Geographic Partners. The agreement, to be finalized in mid-November 2015, will make National Geographic magazines and the Society's cable networks a for-profit venture to be 73% owned by 21st Century Fox, a conventional for-profit corporation. National Geographic Society will continue as a non-profit, however, with an enhanced endowment.
