  2. Function word - Wikipedia

    en.wikipedia.org/wiki/Function_word

    Each function word either: gives grammatical information about other words in a sentence or clause, and cannot be isolated from other words; or gives information about the speaker's mental model as to what is being said. Grammatical words, as a class, can have distinct phonological properties from content words.

  3. Thesaurus (information retrieval) - Wikipedia

    en.wikipedia.org/wiki/Thesaurus_(information...

    A thesaurus is composed by at least three elements: 1-a list of words (or terms), 2-the relationship amongst the words (or terms), indicated by their hierarchical relative position (e.g. parent/broader term; child/narrower term, synonym, etc.), 3-a set of rules on how to use the thesaurus.

  4. Thesaurus - Wikipedia

    en.wikipedia.org/wiki/Thesaurus

    A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms.

  5. Executive functions - Wikipedia

    en.wikipedia.org/wiki/Executive_functions

    Executive functions include basic cognitive processes such as attentional control, cognitive inhibition, inhibitory control, working memory, and cognitive flexibility. Higher-order executive functions require the simultaneous use of multiple basic executive functions and include planning and fluid intelligence (e.g., reasoning and problem-solving).

  6. Function (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Function_(mathematics)

    Some authors [14] reserve the word mapping for the case where the structure of the codomain belongs explicitly to the definition of the function. Some authors, such as Serge Lang , [ 13 ] use "function" only to refer to maps for which the codomain is a subset of the real or complex numbers, and use the term mapping for more general functions.

  7. List of mathematical functions - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_functions

    In mathematics, some functions or groups of functions are important enough to deserve their own names. This is a listing of articles which explain some of these functions in more detail. There is a large theory of special functions which developed out of statistics and mathematical physics.

  8. Functional (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Functional_(mathematics)

    At the same time, the mapping of a function to the value of the function at a point is a functional; here, is a parameter. Provided that f {\displaystyle f} is a linear function from a vector space to the underlying scalar field, the above linear maps are dual to each other, and in functional analysis both are called linear functionals .

  9. Part of speech - Wikipedia

    en.wikipedia.org/wiki/Part_of_speech

    a word that relates words to each other in a phrase or sentence and aids in syntactic context (in, of). Prepositions show the relationship between a noun or a pronoun with another word in the sentence. Conjunction (connects) a syntactic connector; links words, phrases, or clauses (and, but). Conjunctions connect words or group of words.
