A noun phrase – or NP or nominal (phrase) – is a phrase that usually has a noun or pronoun as its head, and has the same grammatical functions as a noun. [1] Noun phrases are very common cross-linguistically, and they may be the most frequently occurring phrase type.
Text linguistics is a branch of linguistics that deals with texts as communication systems.Its original aims lay in uncovering and describing text grammars.The application of text linguistics has, however, evolved from this approach to a point in which text is viewed in much broader terms that go beyond a mere extension of traditional grammar towards an entire text.
Natural language processing (NLP) is a subfield of computer science and especially artificial intelligence.It is primarily concerned with providing computers with the ability to process data encoded in natural language and is thus closely related to information retrieval, knowledge representation and computational linguistics, a subfield of linguistics.
Definition of an ontology – taxonomy – of concepts needed to describe tasks in the topic addressed. Each concept and all their attributes are defined in natural-language words. This ontology will define the data structures the NLP can use in sentences. Definition of one or more top-level sentences in terms of concepts from the ontology.
This is a polynomial-time algorithm accepting an NP-complete language only if P = NP. "Accepting" means it gives "yes" answers in polynomial time, but is allowed to run forever when the answer is "no" (also known as a semi-algorithm). This algorithm is enormously impractical, even if P = NP.
In natural language processing, a word embedding is a representation of a word. The embedding is used in text analysis.Typically, the representation is a real-valued vector that encodes the meaning of the word in such a way that the words that are closer in the vector space are expected to be similar in meaning.

Although the DP analysis is the dominant view in generative grammar, most other grammar theories reject the idea. For instance, representational phrase structure grammars follow the NP analysis, e.g. Head-driven Phrase Structure Grammar, and most dependency grammars such as Meaning-Text Theory, Functional Generative Description, and Lexicase Grammar also assume the traditional NP analysis of ...
A crucial aspect of meaning–text theory is the lexicon, considered to be a comprehensive catalogue of the lexical units (LUs) of a language, these units being the lexemes, collocations and other phrasemes, constructions, and other configurations of linguistic elements that are learned and implemented in speech by users of language. The ...
