  2. Computational linguistics - Wikipedia

    en.wikipedia.org/wiki/Computational_linguistics

    Attempts have been made to determine how an infant learns a "non-normal grammar" as theorized by Chomsky normal form. [9] Research in this area combines structural approaches with computational models to analyze large linguistic corpora like the Penn Treebank , helping to uncover patterns in language acquisition.

  3. Systemic functional linguistics - Wikipedia

    en.wikipedia.org/wiki/Systemic_functional...

    This is a significant difference from other "functional" approaches, such as Dik's functional grammar (FG, or as now often termed, functional discourse grammar) and role and reference grammar. To avoid confusion, the full designation—systemic functional linguistics—is typically used, rather than functional grammar or functional linguistics.

  4. Chomsky hierarchy - Wikipedia

    en.wikipedia.org/wiki/Chomsky_hierarchy

    The Chomsky hierarchy in the fields of formal language theory, computer science, and linguistics, is a containment hierarchy of classes of formal grammars. A formal grammar describes how to form strings from a language's vocabulary (or alphabet) that are valid according to the language's syntax.

  5. Grammaticality - Wikipedia

    en.wikipedia.org/wiki/Grammaticality

    The matter of reliability of L2 grammaticality judgments is an ongoing issue in the research field of second language acquisition. Undeniably, the case of second-language judgments involves participants to make judgments concerning their knowledge of a language system that is not necessarily complete compared to the knowledge of their first ...

  6. 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 ...

  7. Principles and parameters - Wikipedia

    en.wikipedia.org/wiki/Principles_and_parameters

    Principles and parameters is a framework within generative linguistics in which the syntax of a natural language is described in accordance with general principles (i.e. abstract rules or grammars) and specific parameters (i.e. markers, switches) that for particular languages are either turned on or off.

  8. Deep structure and surface structure - Wikipedia

    en.wikipedia.org/wiki/Deep_structure_and_surface...

    Deep structure and surface structure (also D-structure and S-structure although those abbreviated forms are sometimes used with distinct meanings) are concepts used in linguistics, specifically in the study of syntax in the Chomskyan tradition of transformational generative grammar.

  9. Constituent (linguistics) - Wikipedia

    en.wikipedia.org/wiki/Constituent_(linguistics)

    This point is evident with the two tree diagrams above of the sentence Drunks could put off the customers, where the dependency grammar analysis of constituent structure looks very much unlike the phrase structure analysis. The crucial difference across the two analyses is that the phrase structure analysis views every individual word as a ...
