When the scale of a knowledge base is enlarged, the time required to construct it increases, and its management is made difficult. In a frame-based knowledge base, a number of common structures exists in interframe relations. This paper proposes a system in which the knowledge base is regarded as a sample in the construction process, and the common structure is extracted as a rule by which the later construction of the knowledge base is supported. Since the knowledge base contains exceptions, the exceptions are eliminated statistically in the rule extraction. A maintenance mechanism also is introduced, where the rule is rewritten on the basis of the result of application of the rules. The proposed system can also be used for checking the knowledge base to detect whether there is a mismatch.
