In artificial intelligence, symbolic artificial intelligence (also known as classical artificial intelligence or logic-based artificial intelligence) [1] [2] is the term for the collection of all methods in artificial intelligence research that are based on high-level symbolic (human-readable) representations of problems, logic and search. [3]
Selection in general stands in contrast to subcategorization: [2] predicates both select and subcategorize for their complement arguments, whereas they only select their subject arguments. Selection is a semantic concept, whereas subcategorization is a syntactic one. [ 3 ]
An intermediate logic obtained by adding all instances of weak excluded middle to propositional logic. [174] [175] Also called "KC" and "Jankov's logic". [175] logical antirealism The philosophical position that logical truths do not correspond to an independent reality but are instead products of human conventions, language, or thought ...
Propositional logic only considers logical relations between full propositions. First-order logic also takes the internal parts of propositions into account, like predicates and quantifiers. Extended logics accept the basic intuitions behind classical logic and apply it to other fields, such as metaphysics, ethics, and epistemology. Deviant ...
Linguistics is the scientific study of language. [1] [2] [3] The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language), and pragmatics (how the context of use contributes to ...
There are two important ways of specifying these criteria: the syntactic and the semantic approach, sometimes also called the deductive-theoretic and the model-theoretic approach. [5] [17] In this sense, a logic can be defined as a formal language together with either a deductive-theoretic or a model-theoretic account of logical consequence.
Pronounced "A-star". A graph traversal and pathfinding algorithm which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. abductive logic programming (ALP) A high-level knowledge-representation framework that can be used to solve problems declaratively based on abductive reasoning. It extends normal logic programming by allowing some ...
For Peirce, logic also encompassed much of what is now called epistemology and the philosophy of science. He saw logic as the formal branch of semiotics or study of signs, of which he is a founder, which foreshadowed the debate among logical positivists and proponents of philosophy of language that dominated 20th-century Western philosophy.
