Abstract
Abstract An interrogating device which comprises a rule memory (11) for storing forward inference rules utilizable in a forward inference control system (3) or backward inference rule utilizable in a backward inference control system (4), a working memory for storing facts (5), and a forward inference control section (3) operable to add or delete a fact relative to the working memory according to the forward inference rules or a backward inference control section (4) operable to conduct a search according to the backward inference rules.

Claim 1
Independent Claim

An interrogating device which comprises a rule memory storing forward inference rules, which are used in a forward inference control system, and backward inference rules which are used in a backward inference control system, a working memory storing facts, a forward inference control unit operable to add or delete the fact relative to the working memory according to the forward inference rule and a backward inference control unit operable to conduct a search according to the backward inference rule, in which device priority is given to the forward inference rule stored in the rule memory; wherein a command is added to a predetermined rule of one of the forward inference rules and the backward inference rules stored in the rule memory, which command is necessary to perform one of functions of changing the priority added to the forward inference rules, deleting the rule and restoring the rule; wherein in the forward inference control system the change of the priority of the forward inference rules, the deletion of the rule and the restoration of the rule is enabled by the forward inference control unit; and wherein in the forward and backward inference control systems the change of the priority of the forward inference rules, the deletion of the rule and the restoration of the rule is enabled by the backward inference control unit. Accordingly, no special fact is necessary for controlling the change of the priority of the rule and the deletion of the rule, and the change of the priority of the forward inference rules, the deletion of the rule and the restoration of the rule can be easily accomplished by the action of the forward inference rule or backward inference rule.

Accordingly, no special fact is necessary for controlling the change of the priority of the rule and the deletion of the rule, and the change of the priority of the forward inference rules, the deletion of the rule and the restoration of the rule can be easily accomplished by the action of the forward inference rule or backward inference rule.
