using the second knowledge base, and an analysis mechanism for extracting knowledge having high utilization from the fu'st 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.
5353385 INFERENCE METHOD AND APPARATUS FOR USE WITH KNOWLEDGE BASE SYSTEM AND KNOWLEDGE BASE SYSTEM SUPPORT METHOD AND APPARATUS USING THE INFERENCE METHOD AND APPARATUS Tano Shunichi; Masui Shoichi; Nakano Toshihiko Pittsburgh, PA, UNITED STATES 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 of (1) 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 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.
5355444 EXPERT SYSTEM WT1H A PLURALITY OF INDEPENDENT KNOWLEDGE BASES Chirico Neil F Charlotte, NC, UNITED STATES 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.
5386099 SELF-CLEANING PROCESS UTILIZING FUZZY LOGIC AND STOVE FOR CARRYING OUT THE PROCESS Has Uwe Schwindegg, GERMANY Assigned to Bosch-Siemens Hausgeraete GmbH A pyrolytic self-cleaning stove includes at least one wall region defming an oven chamber, a muffle disposed in the at least one wall region, a heating element with additional ambient air heating for operating the muffle, an ambient air blower for ventilating the muffle, a device associated with the muffle for pyrolytic selfcleaning, and a sensor array disposed in the cooking chamber for detecting oven soiling values caused by operation. A pyrolytic selfcleaning method for stoves includes on-line optimization of a definable pyrolysis temperature range up to approximately 500 degrees C. by fuzzy-controlling a transient state for a temperature starting value with a regulating device, to avoid a heating startup peak with a fuzzy control step; recognizing subsiding of the transient state and initializing an optimized heating time referred to the fuzzy control step,
