    A cloze test (also cloze deletion test or occlusion test) is an exercise, test, or assessment in which a portion of text is masked and the participant is asked to fill in the masked portion of text. Cloze tests require the ability to understand the context and vocabulary in order to identify the correct language or part of speech that belongs ...

  3. Syntactic category - Wikipedia

    en.wikipedia.org/wiki/Syntactic_category

    The parts of speech that form closed classes and have mainly just functional content are called functional categories: Lexical categories Adjective (A) and adjective phrase (AP), adverb (Adv) and adverb phrase (AdvP), noun (N) and noun phrase (NP), verb and verb phrase (VP), preposition and prepositional phrase (PP)

  4. Lemmatization - Wikipedia

    en.wikipedia.org/wiki/Lemmatization

    Unlike stemming, lemmatization depends on correctly identifying the intended part of speech and meaning of a word in a sentence, as well as within the larger context surrounding that sentence, such as neighbouring sentences or even an entire document. As a result, developing efficient lemmatization algorithms is an open area of research.

  7. Phrase structure rules - Wikipedia

    en.wikipedia.org/wiki/Phrase_structure_rules

    Phrase structure rules break sentences down into their constituent parts. These constituents are often represented as tree structures (dendrograms). The tree for Chomsky's sentence can be rendered as follows: A constituent is any word or combination of words that is dominated by a single node. Thus each individual word is a constituent.

  8. Part-of-speech tagging - Wikipedia

    en.wikipedia.org/wiki/Part-of-speech_tagging

    Part-of-speech tagging is harder than just having a list of words and their parts of speech, because some words can represent more than one part of speech at different times, and because some parts of speech are complex. This is not rare—in natural languages (as opposed to many artificial languages), a large percentage of word-forms are ...

  9. Word-sense disambiguation - Wikipedia

    en.wikipedia.org/wiki/Word-sense_disambiguation

    Both WSD and part-of-speech tagging involve disambiguating or tagging with words. 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.
