Many Prolog systems omit the occurs check, and so succeed at the substitution. Alas, the result is the term X->X where X is no longer a free logic variable.

As a meta-language specifying the system, a logic programming language, namely, Prolog is adopted. All of proof rules, axioms, definitions, theorems and also proofs can be described as predicates of Prolog. So Prolog can be used to verify whether deductions are valid or not. Natural deduction proof editor and checker This is a demo of a proof checker for Fitch-style natural deduction systems found in many popular introductory logic textbooks.

2019-12-13 Prolog is used in artificial intelligence applications such as natural language interfaces, automated reasoning systems and expert systems. Expert systems usually consist of a data base of facts and rules and an inference engine, the run time system of Prolog … Natural deduction for propositional logic A ∧ B conjI A ∧ B C conjE A ∨ B A ∨ B disjI1/2 A ∨ B C disjE A −→ B impI A −→ B C impE A = B iffI A =⇒ B iffD1 B =⇒ A iffD2 ¬ A notI ¬ A C notE – p.6 Prolog and Natural Language Analysis.

Prolog can be introduced without resolution by viewing Prolog derivations of query Q from program P as natural deduction proofs of the goal Q from premisses P. A Prolog program consists of definite clauses with the general form ⁠, where A, B 1,…,B n are atoms. In the case n = 0 the clause has the form A and is called a fact; otherwise it is called a rule. Any variables in a clause are implicitly universally quantified.

Some facts are relying on the logical deduction to make it. 1992-02-26 · Keronen S. (1993) Natural deduction proof theory for logic programming. In: Lamma E., Mello P. (eds) Extensions of Logic Programming. ELP 1992.
