摘要： PURPOSE:To correct the rule in a knowledge base speedily and accurately by refining a correction plan for the possibly erroneous rule of the knowledge base and a searched rule. CONSTITUTION:If the conclusion event in teacher data which is generated previously does not coincide with a conclusion inferred from the initial event in the teacher data, the rule sequence used to derive this conclusion is retrieved in the knowledge base 21 and while a rule to be corrected is selected in this rule sequence and recorded on a recording device 14, the correction plan for the rule is recorded. Then when the conclusion event coincides with the conclusion inferred from the initial event, a rule sequence used to derive this conclusion is searched for in the knowledge base 21 and the respective rules in this searched rule sequence are recorded as rules which are not corrected. Consequently, mutually contradictory correction plans in the recorded rules are deleted and the correction plan for the rules is accurately displayed.
