Integrating rule-based and case based reasoning

For problem solving in complex, real world situations, it is useful to integrate RBR and CBR. This paper presents an approach to achieve a compact and seamless integration of RBR and CBR within the base architecture of rules.

In CBR, the concept of similarity is cast as the complement of the distance between cases. In RBR the transitivity of similarity is the basis for the approximate deductions based on the generalised modus ponens.

Rule-based reasoning (RBR) and case-based reasoning (CBR) have emerged as two important and complementary reasoning methodologies in artificial intelligence (AI).
