Resolution (logic) In mathematical logic and automated theorem proving, resolution is a rule of inference leading to a refutation-complete theorem-proving technique for sentences in propositional logic and first-order logic. For propositional logic, systematically applying the resolution rule acts as a decision procedure for formula ...
Three-act structure. The three-act structure is a model used in narrative fiction that divides a story into three parts (acts), often called the Setup, the Confrontation, and the Resolution. It was popularized by Syd Field in his 1979 book Screenplay: The Foundations of Screenwriting. Based on his recommendation that a play have a "beginning ...
Sentence diagram. A sentence diagram is a pictorial representation of the grammatical structure of a sentence. The term "sentence diagram" is used more when teaching written language, where sentences are diagrammed. The model shows the relations between words and the nature of sentence structure and can be used as a tool to help recognize which ...
First-order logic —also called predicate logic, predicate calculus, quantificational logic —is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science. First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables.
Propositional calculus. The propositional calculus[a] is a branch of logic. [1] It is also called propositional logic, [2] statement logic, [1] sentential calculus, [3] sentential logic, [1] or sometimes zeroth-order logic. [4][5] It deals with propositions [1] (which can be true or false) [6] and relations between propositions, [7] including ...
Conjunctive normal form. In Boolean logic, a formula is in conjunctive normal form (CNF) or clausal normal form if it is a conjunction of one or more clauses, where a clause is a disjunction of literals; otherwise put, it is a product of sums or an AND of ORs. As a canonical normal form, it is useful in automated theorem proving and circuit theory.
Logical reasoning is a mental activity that aims to arrive at a conclusion in a rigorous way. It happens in the form of inferences or arguments by starting from a set of premises and reasoning to a conclusion supported by these premises. The premises and the conclusion are propositions, i.e. true or false claims about what is the case.
In linguistics, immediate constituent analysis or IC analysis is a method of sentence analysis that was proposed by Wilhelm Wundt and named by Leonard Bloomfield.The process reached a full-blown strategy for analyzing sentence structure in the distributionalist works of Zellig Harris and Charles F. Hockett, [1] and in glossematics by Knud Togeby. [2]
