In situation theory, situation semantics (pioneered by Jon Barwise and John Perry in the early 1980s) [1] attempts to provide a solid theoretical foundation for reasoning about common-sense and real world situations, typically in the context of theoretical linguistics, theoretical philosophy, or applied natural language processing,
Some languages form the negative of existential clauses irregularly; for example, in Russian, есть yest ("there is/are") is used in affirmative existential clauses (in the present tense), but the negative equivalent is нет nyet ("there is/are not"), used with the logical subject in the genitive case.
In predicate logic, an existential quantification is a type of quantifier, a logical constant which is interpreted as "there exists", "there is at least one", or "for some". It is usually denoted by the logical operator symbol ∃, which, when used together with a predicate variable, is called an existential quantifier (" ∃ x " or " ∃( x ...
The existential closure in K of a member M of K, when it exists, is, up to isomorphism, the least existentially closed superstructure of M. More precisely, it is any extensionally closed superstructure M ∗ of M such that for every existentially closed superstructure N of M , M ∗ is isomorphic to a substructure of N via an isomorphism that ...
Types in the theory are defined by applying two forms of type abstraction, starting with an initial collection of basic types. Basic types: TIM: the type of a temporal location; LOC: the type of a spatial location; IND: the type of an individual; RELn: the type of an n-place relation; SIT: the type of a situation; INF: the type of an infon
The situation, task, action, result (STAR) format is a technique [1] used by interviewers to gather all the relevant information about a specific capability that the job requires. [ citation needed ] Situation : The interviewer wants you to present a recent challenging situation in which you found yourself.
An existential graph is a type of diagrammatic or visual notation for logical expressions, created by Charles Sanders Peirce, who wrote on graphical logic as early as 1882, [1] and continued to develop the method until his death in 1914. They include both a separate graphical notation for logical statements and a logical calculus, a formal ...
In predicate logic, existential generalization [1] [2] (also known as existential introduction, ∃I) is a valid rule of inference that allows one to move from a specific statement, or one instance, to a quantified generalized statement, or existential proposition.
