Abstract

This paper presents an approach to non-monotonic inheritance in an object-oriented logic programming framework. Inheritance as sublation, achieved through predicate extension and exception, not only provides a very flexible mechanism for software reuse but also is very philosophical. Taking the (iterated least fixpoint) well-founded model semantics to traditional logic programs as a basis, the declarative semantics is also explored.
