JPS6465637A - Knowledge control system considering relation including effective range - Google Patents

Abstract

PURPOSE:To simply and efficiently execute knowledge processing having an effective range by providing the titled system with a control means for controlling knowledge in a knowledge storing means every effective range considering the including relation of the effective range. CONSTITUTION:Under control based upon a control means 2, the effective range is checked by processing A. Processing having no effective range is regarded as infinite processing. Processing B1 checks whether the effective range found by the processing A is included in a range 4-1 or not, processing B2 checks whether the effective range is included in a range 4-2 or not and processing Bn checks whether the effective range is included in a range 4-n or not. Processing C1 executes processing such as the retrieval, formation, updating, and deletion of the knowledge and the batch erasing of the knowledge at the time of an end about a subknowledge base 5-1. When the knowledge does not exist as the result of retrieval of knowledge to be referred during the processing, subknowledge bases 5-2-5-n and 5-0 are retrieved until the knowledge is detected. Similarly, the knowledge is retrieved until detection in processing C2-Cn. Processing D executes processing in a subknowledge base 5-0 having an infinite effective range, i.e. universal knowledge.
