APPARATUS AND METHOD FOR GENERATING DISCRIMINATION NETWORK FOR EXPERT SYSTEM

摘要

PURPOSE: To obtain a guide for identifying lost data by installing a storage device that holds information for identifying what of the conditions represented with part of nodes is satisfied by the value of a data element, and testing the stored information based on the representation consisting of the conditions. CONSTITUTION: Conditions are represented with nodes 38, 40, 42, and 44, further based on the value of a data element assigned to a network where the interrelation between the conditions with respect to the representation is represented with internode links, information for identifying what of the conditions represented with at least a part of the nodes is satisfied the value of the data element is stored in memories 52 and 54, and on the basis of evaluating the representation consisting of the conditions, the information stored is tested in accordance with the representation. With this, an item where data is lost can be efficiently identified, and can be easily retrieved without the necessity of taking special rules, rules for vacant condition, or reverse chaining into account.
