System for generating knowledge base in which sets of common causal

Abstract

A knowledge base generating system includes a knowledge base having a first knowledge base containing sets of causal relation knowledge describing cause-effect relations of events taking place within a target machine, and having a second knowledge base containing sets of membership knowledge describing a structure of members of the target machine, each event of the cause-effect relations having data to identify one of the members, so that the first and second knowledge bases have mutually retrievable data, a retrieval part for retrieving a number of first members in the second knowledge base, which members correspond to similar causal relation knowledge sets within the first knowledge base, a detection part for detecting whether or not there is a high-rank member in the second knowledge base, the high-rank member corresponding to each of the first members on the basis of the membership knowledge of the second knowledge base, and a commonizing part for generating a common causal relation knowledge set, corresponding to the high-rank member, in the first knowledge base, when the high-rank member is detected.
