KSL/Logic: integration of logic with objects

Abstract

KSL/Logic is an integration of logic and object-oriented programming that adds the declarative framework and deductive reasoning of logic programming to the powerful modeling capabilities of the object-oriented paradigm. Predicates, logic expressions, and the generalized search protocol of KSL/Logic are implemented as an integral part of KSL, a reflective, object-oriented programming language. KSL/Logic provides capabilities that go beyond those of Prolog to permit domain-based reasoning, functional arguments, matching of complex object patterns, and object representation of facts. The syntax and semantics of KSL/Logic are described, and the object implementation of its predicate resolution is examined.<>
