  2. Model theory - Wikipedia

    en.wikipedia.org/wiki/Model_theory

    The model-theoretic viewpoint has been useful in set theory; for example in Kurt Gödel's work on the constructible universe, which, along with the method of forcing developed by Paul Cohen can be shown to prove the (again philosophically interesting) independence of the axiom of choice and the continuum hypothesis from the other axioms of set ...

  3. 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.

  4. Two-source hypothesis - Wikipedia

    en.wikipedia.org/wiki/Two-source_hypothesis

    The hypothesis is a solution to what is known as the synoptic problem: the question of how best to account for the differences and similarities between the three synoptic gospels, Matthew, Mark and Luke. The answer to this problem has implications for the order in which the three were composed, and the sources on which their authors drew.

    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".

  7. Similarity (philosophy) - Wikipedia

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

    A "system of weights" in the form of a set of criteria is to guide us in assessing the degree of similarity between possible worlds. [7] 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]

  8. Working hypothesis - Wikipedia

    en.wikipedia.org/wiki/Working_hypothesis

    For Putnam, the working hypothesis represents a practical starting point in the design of an empirical research exploration. A contrasting example of this conception of the working hypothesis is illustrated by the brain-in-a-vat thought experiment. This experiment involves confronting the global skeptic position that we, in fact, are all just ...

    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 .
