Title:
INFERENCE DEVICE
Document Type and Number:
Japanese Patent JP3293895
Kind Code:
B2
Abstract:
PURPOSE: To accelerate inference processing, further, to facilitate the construction of a knowledge base and to provide versatility by containing attribute data for deciding the priority order of input requests in an event requiring the input of data.
CONSTITUTION: A numerical event Fij and a logical event Aij required the input of data contain the attribute data for deciding the priority of input requests, and an inference part executes inference while searching the respective events Fij and Aij successively from the high priority. On the other hand, concerning a rule Ri expressing the relation of cause and effect between the respective events, the attribute data for deciding the priority of inference execution are contained as well, and the inference part selects any specified group based on respective measure signals or the data input from a user and defines only the rule group divided into that group as the object of search. Therefore, a search period of time can be shortened in comparison with the case of searching all the rules.
