Abstract

A computer system performs processing such as inference processing by sequentially executing rules each with its if-part stored in a working memory. The computer system comprises a production memory storing rules such as the laws of experience and nature and a working memory storing facts and hypothesis. The processing system processes the case where the rules include variables. To this end, this processing system groups the if-items and then-items which may be matched with each other depending on variable values, and takes representatives of the respective grouped items as association items to store the facts by the local parts of the association items.
