An object-oriented inference model and its knowledge representation

Knowledge representation is one of the kernel problems in research of expert system. Production rule and procedure knowledge play an important role in the development of expert system. This paper analyzed and designed an inference model (RBIM) based on production system in object oriented programming language, which can combine representation of predication and procedure. On the basis of object oriented knowledge representation, the model supports proposition object, predication object and procedure object as basic element of production rule. RBIM provides a good interface on knowledge representation.
