Abstract
Described is a processing system for knowledge data base in which indices representing the degrees of certainty of causal relations between an event and plural events relevant to the first-mentioned event are stored. The system has an input unit for inputting information on those actually experienced among events inferred based on the knowledge data base, an updating unit for updating the indices so that, among the plural causal relations, the certainty of the causal relation corresponding to the actually experienced event inputted by the input means is made higher relative to the certainties of the other causal relations, and a storing unit for storing back the thus-updated indices again in the knowledge data base. This allows an expert system with the processing system to perform inference with higher certainty.
