5355444 Expert system with a plurality of independent knowledge bases
IV
New Patents
extracting knowledge required to solve problems within a certain range from detailed knowledge automatically . The expert system includes a first knowledge base for storing detailed knowledge, a second knowledge base for storing compiled knowledge, an inference mechanism for solving a problem by using the second knowledge base, and an analysis mechanism for extracting knowledge having high utilization from the first knowledge base and storing the extracted knowledge in the second knowledge base. The analysis mechanism analyzes a problem solving process example and stores a combination of knowledge which is frequently used as one compiled knowledge and knowledge which is frequently used independently as one compiled knowledge from the first knowledge base into the second knowledge base.
thereof and (2) an operation description part stipulating an operation to be executed when the condition is satisfied. For an inference processing, a rule for which a condition of its condition description part is satisfied is executed according to an operation described in the operation description part. A condition judging sequence is specified for satisfaction of a condition for each frame of the condition description part of the rule. It is also specified whether or not information related to a processing result obtained from a condition judge processing on each said frame is stored in a memory. Condition judgements are achieved for satisfaction of conditions respectively associated with the frames of the condition description part according to the specified sequence based on the processing results in the memory, thereby conducting a reasoning operation.
5353385 INFERENCE M E T H O D AND APPARATUS FOR USE WITH KNOWLEDGE BASE SYSTEM AND KNOWLEDGE BASE SYSTEM SUPPORT METHOD AND APPARATUS USING THE INFERENCE METHOD AND APPARATUS Shunichi Tano, Shoichi Masui, Toshihiko Nakano assigned to Hitachi Ltd An inference method and an inference apparatus for use with a knowledge base system and knowledge base system supporting method and apparatus using the inference method and apparatus wherein there are employed rules each being comprised of a set o f ( l ) a condition description part including a condition stipulating a plurality of states of a frame representing an object and constituting an object world of at least one pair of a slot and a value
5355444 EXPERT SYSTEM WTIH A PLURALITY OF INDEPENDENT KNOWLEDGE B A S E S Neil F Chirico assigned to International Business Machines Corporation The present invention is an expert system with a plurality of independent knowledge bases, including a process and apparatus for employing an inference engine to select one of the knowledge bases based on one or more key factors. In particular, an embodiment using a batch mode for input of data to the expert system is disclosed, based on which, one of the stored independent knowledge bases is selected and employed in connection with the inference engine. This expert system has application to maintenance of a document processing system, where one of several types of maintenance is selected, causing a respective knowledge base or set of rules to be selected.
