    [8]: 7 The blow-up in grammar size depends on the order between DEL and BIN. It may be exponential when DEL is done first, but is linear otherwise. UNIT can incur a quadratic blow-up in the size of the grammar. [8]: 5 The orderings START,TERM,BIN,DEL,UNIT and START,BIN,DEL,UNIT,TERM lead to the least (i.e. quadratic) blow-up.

  3. Context-free grammar - Wikipedia

    en.wikipedia.org/wiki/Context-free_grammar

    The especially simple form of production rules in Chomsky normal form grammars has both theoretical and practical implications. For instance, given a context-free grammar, one can use the Chomsky normal form to construct a polynomial-time algorithm that decides whether a given string is in the language represented by that grammar or not (the ...

    In theoretical computer science and formal language theory, a regular language (also called a rational language) [1] [2] is a formal language that can be defined by a regular expression, in the strict sense in theoretical computer science (as opposed to many modern regular expression engines, which are augmented with features that allow the recognition of non-regular languages).

    A language model is a model of natural language. [1] Language models are useful for a variety of tasks, including speech recognition, [2] machine translation, [3] natural language generation (generating more human-like text), optical character recognition, route optimization, [4] handwriting recognition, [5] grammar induction, [6] and information retrieval.

    The Conlang Flag, a symbol of language construction created by subscribers to the CONLANG mailing list, which represents the Tower of Babel against a rising sun. A constructed language (shortened to conlang) [a] is a language whose phonology, grammar, orthography, and vocabulary, instead of having developed naturally, are consciously devised for some purpose, which may include being devised ...

  9. Functional linguistics - Wikipedia

    en.wikipedia.org/wiki/Functional_linguistics

    The term 'functionalism' or 'functional linguistics' became controversial in the 1980s with the rise of a new wave of evolutionary linguistics. Johanna Nichols argued that the meaning of 'functionalism' had changed, and the terms formalism and functionalism should be taken as referring to generative grammar, and the emergent linguistics of Paul Hopper and Sandra Thompson, respectively; and ...
