  2. Distributional semantics - Wikipedia

    en.wikipedia.org/wiki/Distributional_semantics

    The distributional hypothesis in linguistics is derived from the semantic theory of language usage, i.e. words that are used and occur in the same contexts tend to purport similar meanings. [ 2 ] The underlying idea that "a word is characterized by the company it keeps" was popularized by Firth in the 1950s.

  3. Model theory - Wikipedia

    en.wikipedia.org/wiki/Model_theory

    In mathematical logic, model theory is the study of the relationship between formal theories (a collection of sentences in a formal language expressing statements about a mathematical structure), and their models (those structures in which the statements of the theory hold). [1]

  4. Contrastive analysis - Wikipedia

    en.wikipedia.org/wiki/Contrastive_analysis

    The theoretical foundations for what became known as the contrastive analysis hypothesis were formulated in Robert Lado's Linguistics Across Cultures (1957). In this book, Lado claimed that "those elements which are similar to [the learner's] native language will be simple for him, and those elements that are different will be difficult".

  5. Similarity (philosophy) - Wikipedia

    en.wikipedia.org/wiki/Similarity_(philosophy)

    For example, avoiding widespread violations of the laws of nature ("big miracles") is considered an important factor for similarity while proximity in particular facts has little impact. [7] One objection to Lewis' approach is that the proposed system of weights captures not so much our intuition concerning similarity between worlds but instead ...

  6. Two-source hypothesis - Wikipedia

    en.wikipedia.org/wiki/Duhem–Quine_thesis

    In practice the politics and theology of the day determined the result of the dispute, but the nature of the controversy was a clear example of how different bundles of (usually implicit) auxiliary assumptions could support mutually inconsistent hypotheses concerning a single theory. In terms of either version of the Duhem–Quine thesis it ...

  8. Unifying theories in mathematics - Wikipedia

    en.wikipedia.org/wiki/Unifying_theories_in...

    (Examples include group theory, Galois theory, control theory, and K-theory.) In particular there is no connotation of hypothetical. Thus the term unifying theory is more like a sociological term used to study the actions of mathematicians. It may assume nothing conjectural that would be analogous to an undiscovered scientific link.

  9. Two-gospel hypothesis - Wikipedia

    en.wikipedia.org/wiki/Two-gospel_hypothesis

    The two-gospel hypothesis or Griesbach hypothesis is that the Gospel of Matthew was written before the Gospel of Luke, and that both were written earlier than the Gospel of Mark. [1] It is a proposed solution to the synoptic problem , which concerns the pattern of similarities and differences between the three Gospels of Matthew , Mark , and Luke .
