Rule of inference - Wikipedia, the free encyclopedia
In logic, a rule of inference (also called a transformation rule ) is a syntactic rule used in a formal system which is used to produce valid statements within that system. A formal system is comp...

List of rules of inference - Wikipedia, the free encyclopedia
This is a list of rules of inference, logical laws that relate to mathematical formulae. Rules of inference are syntactical transformation rules which one can use to infer a conclusion from a premis...

Formal inference rules and proofs ... An inference rule formalizes what steps are allowed in proofs. We'll use this list of valid inference rules as our definition, but, this is just one set of possible inference rules, and other people could use slightly different ones.

Summary: A set of inference rules for propositional logic ... Table 1: Our propositional inference rules ... This set of inference rules is based upon Discrete Mathematics with a Computer by Hall and O'Donnell (Springer, 2000) and The Beseme Project.

Although any valid pattern of inferences could be used in this proof procedure, we will make things easier by relying on a very short list of valid argument forms. Each new step that we take in constructing a proof must then be a substitution-instance of one of these rules of inference.

Glossary of Religion and Philosophy - inference rules ... Complex deductive arguments can be judged valid or invalid based on whether or not the steps in that argument follow the nine basic rules of inference. These rules of inference are all relatively simple, although when presented in formal terms they can look...

Inference Rules of Propositional Calculus used in Natural Deduction ... Natural Deduction uses two kinds of rules: Rules of inference and rules of replacement. (The term "rule of inference" is often used to cover both types.) The former are tautologous conditionals (that is, ... Table 1. Inference Rules...

"The present list of 19 rules of inference constitutes a COMPLETE system of truth-functional logic, in the sense that it permits the construction of a formal proof of validity for ANY valid truth-functional argument." (FN1)

CiteSeerX - Document Details (Isaac Councill, Lee Giles): In this paper, we propose an unsupervised method for discovering inference rules from text, such as "X is author of Y X wrote Y", "X solved Y X found a solution to Y", and "X caused Y Y is triggered by X". Inference rules are extremely important in many fields such ...
