The distributional hypothesis in linguistics is derived from the semantic theory of language usage, i.e. words that are used and occur in the same contexts tend to purport similar meanings. [ 2 ] The underlying idea that "a word is characterized by the company it keeps" was popularized by Firth in the 1950s.
Distributionalism can be said to have originated in the work of structuralist linguist Leonard Bloomfield and was more clearly formalised by Zellig S. Harris. [1] [3]This theory emerged in the United States in the 1950s, as a variant of structuralism, which was the mainstream linguistic theory at the time, and dominated American linguistics for some time.

In linguistics, Immediate Constituent Analysis (ICA) is a syntactic theory which focuses on the hierarchical structure of sentences by isolating and identifying the constituents. While the idea of breaking down sentences into smaller components can be traced back to early psychological and linguistic theories, ICA as a formal method was ...
Latent semantic analysis (LSA) is a technique in natural language processing, in particular distributional semantics, of analyzing relationships between a set of documents and the terms they contain by producing a set of concepts related to the documents and terms.
The syntax is the single generative engine that forms sound-meaning correspondences, both complex phrases and complex words. This approach challenges the traditional notion of the Lexicon as the unit where derived words are formed and idiosyncratic word-meaning correspondences are stored.
For example, in English, the speech sounds [pʰ] and [b̥] can both occur at the beginning of a word, as in the words pat and bat. Since [pʰ] and [b̥] both occur in the same phonological environment (i.e. at the beginning of a word) but change the meaning of the word they form, they are in contrastive distribution and therefore provide ...
It disregards word order (and thus most of syntax or grammar) but captures multiplicity. The bag-of-words model is commonly used in methods of document classification where, for example, the (frequency of) occurrence of each word is used as a feature for training a classifier. [1] It has also been used for computer vision. [2]
The usages an aardvark and a bear are grammatical, but the usages *a aardvark and *an bear are ungrammatical (as is marked with "*" in linguistics). The form an is used before a word that begins with a vowel sound. That can be notated as "__ V". The form a is used before a word beginning with a consonant sound. That can be notated as "__ C".
