ABSTRACT:
Disclosed in this invention is a knowledge acquisition tool for facilitating a construction of a knowledge base in an expert system, including: a case preprocessing part 21 for checking whether or not data constituting individual cases on which a knowledge base is based satisfy a predetermined evaluation criterion and deleting or changing non-satisfying cases; a rule generation part 22 for generating rules by extracting regularities from the cases processed by preprocessing part 21; and a rule evaluation part 32 for evaluating the rules generated by the rule generation part 22.
