Abstract: A mechanism for tracing the utilization of rules in expert systems during periods of practical usage is proposed. Statistics related to the utilization of each rule help the designer to re‐evaluate the appropriateness of each rule, so that over‐utilized rules may be expanded and unnecessary ones deleted. By incorporating such a mechanism, the efficiency of maintaining and updating expert systems is improved.
