In linguistics, a word sense is one of the meanings of a word. For example, a dictionary may have over 50 different senses of the word play, each of these having a different meaning based on the context of the word's usage in a sentence, as follows:
In each sentence we associate a different meaning of the word "play" based on hints the rest of the sentence gives us.
People and computers, as they read words, must use a process called word-sense disambiguation to find the correct meaning of a word. This process uses context to narrow the possible senses down to the probable ones. The context includes such things as the ideas conveyed by adjacent words and nearby phrases, the known or probable purpose and register of the conversation or document, and the orientation (time and place) implied or expressed. The disambiguation is thus context-sensitive.
A word sense may correspond to either a seme (the smallest unit of meaning) or a sememe (the next larger unit of meaning), and polysemy is the property of having multiple semes or sememes and thus multiple senses.
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.
Natural language processing (NLP) is a field of computer science, artificial intelligence, and computational linguistics concerned with the interactions between computers and human (natural) languages. As such, NLP is related to the area of human–computer interaction. Many challenges in NLP involve natural language understanding, that is, enabling computers to derive meaning from human or natural language input, and others involve natural language generation.
The history of NLP generally starts in the 1950s, although work can be found from earlier periods. In 1950, Alan Turing published an article titled "Computing Machinery and Intelligence" which proposed what is now called the Turing test as a criterion of intelligence.
The Georgetown experiment in 1954 involved fully automatic translation of more than sixty Russian sentences into English. The authors claimed that within three or five years, machine translation would be a solved problem. However, real progress was much slower, and after the ALPAC report in 1966, which found that ten-year-long research had failed to fulfill the expectations, funding for machine translation was dramatically reduced. Little further research in machine translation was conducted until the late 1980s, when the first statistical machine translation systems were developed.
In neuropsychology, linguistics and the philosophy of language, a natural language or ordinary language is any language that develops naturally in humans through use and repetition (typically, in their first few years of life) without any conscious planning or premeditation of their own. Almost always, therefore, these are the languages human beings use to communicate with each other, whether by speech, signing, touch or writing. They are distinguished from constructed and formal languages such as those used to program computers or to study logic.
Though the exact definition varies between scholars, natural language can broadly be defined in contrast to artificial or constructed languages (such as computer programming languages and international auxiliary languages) and to other communication systems in nature (such as bees' waggle dance). Definitions of "natural language" also usually state or imply that a "natural" language is one that any cognitively normal human infant is able to learn and whose development has been through use rather than by prescription. An unstandardized language such as African American Vernacular English, for example, is a natural language, whereas a standardized language such as Standard American English is, in part, prescribed.

Here is a lesson explaining when sentences have sense and when they have reference. Explanation of deixis is also available. There are exercises at the end of the video to test your understanding. You are welcome to comment with any questions you have in mind :)
Do you ever wonder why we park a car in a "driveway" but drive on a "parkway"? Why do we have "toes", not "footfingers"? And why do we brush our teeth with a "toothbrush" and "toothpaste" instead of a "teethbrush" and "teethpaste"? Sometimes, it looks like English makes no sense! I understand your frustration, so in this lesson, I will make sense of the senseless and look at some vocabulary that can confuse English learners.

Every one of my lyrics when you hear it
it'll burn your face as sulfuric acid
If you're holdin' the microphone I suggest you pass it.
Hand it over quickly
Sickly's the only way I know how to drop it
Every time I kick it people look at me like my name's
Ripley's Believe it or Not
Got a wonderful time slot here at the Zero Hour
Been laughed at for rappin' ever since I was a little coward
By all the kids who towered over me
Overpowered me and beat the shit out of my face
Like it's the job clock in an hour
And how are we the ones who powered these machines
And we can't get nothin' done, we controlled by kings and queens
The unseen son, the one in the attic
Hope the dream don't come true
America, she loves you
Without us who would back up the groceries
Or price up the clothes that you normally don't see
On average joes, oh that's me
Little dirtbag rapper and glad to be
I like my hip-hop dropped in tip-top condition
I keep on spittin' but no one listens
I must drop fire, I can not wait for a fall
This is our only hope, this is a war
This is a war
*Every picture you see is a reflection of marketing
The targeting of certain audiences as only a major corporation could
It's simple: They feed you shit. Just stop eating it, genius.
Run up in the Universal Office and find Doug Morris
Pound him in his office, his life ain't real pretty
Like bitches that sing choruses
These forces are forcin' us to try to relate
In spite of what they lead you to believe in the first place
Can't move in the city 'cause it's packed so tight
Everybody up in my business, dissin' the lyrics I write
Dismissin' my raps off their shoulder like the never happened
Actin' so thuggish like they tough like Tinactin
It's rubbish, it's all bubble gum to me
Nobody bumpin' me stoppin' by your record company
I'ma flatten MC's with platinum CDs
You see these two fists? They each got MT
Tons of Budweiser, got balls of steel wire
Like a sidewalk and supposedly ya'll are keepin' it real
But mostly ya just provoke and poke at me
And hopefully you remember your jokes to me
I like my hip-hop dropped in tip-top condition
I keep on spittin' but no one listens
I must drop fire, I can not wait for a fall
This is our only hope, this is a war
This is a war
*If ??? rap in you was approved by tests you'd see it's got nothin' to do with you.
The real gangstas are old white men putting these records out.
Hip-hop? That's the last thing they give a fuck about.*
By any means necessary I'm buryin' advesary
Every vocal performance it's important to stary vary
If you wanna feed all then you got motorcall
And I'm on the line, we can meet at the grassy knoll at ten
Maybe rap was never hip-hop to them
Seems like it's just a cash crop to them
So don't claim you spit it proper then
This war must never end
I can no longer pretend to be down
If I die in a battle that's fine
I got a potion named Revolution number 9
I got a heart that beats for the art
This is hip-hop for the love
Not a 1 on the charts
I like my hip-hop dropped in tip-top condition
I keep on spittin' but no one listens
I must drop fire, I can not wait for a fall
This is our only hope, this is a war
This is a war
This is a war, this is a war
This is a war, this is a war
