Circuit Minimization Techniques Applied to Knowledge Engineering

Pasik, Alexander J.

Often knowledge engineers encounter situations during the interviewing process in which experts have difficulty expressing the knowledge to be captured. In these situations, the experts cannot readily present their knowledge so that the knowledge engineers can encode it in the chosen formalism (for example, in production rules). During the development of an expert system for underwriting homeowner insurance policies, this situation was occasionally encountered. When the experts could not express their knowledge in chunks suitable for encoding directly in production rules, circuit minimization techniques were used to construct the set of production rules from exhaustive tables of acquired knowledge. The techniques also served to find errors in the acquired knowledge. Circuit minimization techniques, therefore, have been found to provide valuable assistance in the knowledge engineering process, both in the acquisition and verification of knowledge.
