Towards a Declarative Semantics of Inheritance with Exceptions

This paper presents a declarative semantics of compositional inheritancein an object-oriented logic programming' framework wit h explicit exceptions,based on the iterated least Aspoint semantics to normal logic programs. Tak-ing logic objects with exceptions as a ldnd of nonmonotonic theory, the nonmonotonicity of inheritance is achieved, which is of importance for modelingincomplete knowledge and requirement specffications in both artificial intelli-gence and softwa-re engineering.
