ABSTRACT:
An inferential method is disclosed, where fact information and a time tag assigned thereto are matched and stored. A rule group is stored. A pattern match of the fact information and the rule group is executed. A combination of the fact information and the rule group is selected. When a plurality of combinations have been selected, one of them is further selected. The selected rule is executed and new fact information in the working memory is created. When new fact information is created to the working memory by executing the rule, if the time tag assigned to the fact information exceeds the given value, the time tag which has been assigned to the fact information in the working memory is reassigned.
