DEVICE AND INFERENCE DEVICE FOR CORRECTABLE KNOWLEDGE ACQUISITION, AND CORRECTABLE KNOWLEDGE ACQUIRING METHOD AND INFERENCE METHOD

摘要

PROBLEM TO BE SOLVED: To easily acquire and correct knowledge and derive an accurate solution. ;SOLUTION: A correction knowledge acquisition part 10 derive a primary solution of a problem inputted from a problem input part 12 through the inference of a knowledge base inference part 13 based on an existent knowledge base 14. An instance base inference part 15 generates the process of derivation of the primary solution by the knowledge base inference part 13 as a retrieval key and performs retrieval from the exceptional instance base 18 by an exceptional instance base retrieval part 17 by using the retrieval key. Then a contradiction point is traced in the existent knowledge base 14 according to exceptional instances and contradiction knowledge is shown to an expert to obtain a metarule. This obtained metarule is applied to the existent knowledge base 14 to perform inference.;COPYRIGHT: (C)1997,JPO
