Abstract

Effective reuse of Knowledge Bases (KBs) often entails the expensive task of identifying plausible KB-PS (Problem Solver) combinations. We propose a novel technique based on Constraint Satisfaction to enable more rapid identification of incompatible KBs, leaving fewer combinations on which to conduct a thorough investigation. In this paper, we describe our investigation process, its tools, and the latest empirical results applied to non-binary problems that demonstrate our relaxation approach is an effective method for plausibility testing.
