Title: Knowledge base system
Inventor: TANO SHUNICHI
IPC: G06F9/44
Filed: 1987-10-09
Abstract: PURPOSE:To attain the explanation to a user of a knowledge base system without using a rule itself by describing the meaning information to the rule having the important meaning and using this meaning information only to perform the explanation. CONSTITUTION:When an event name to be inspected is supplied and a knowledge base system performs the backward inference to decide the genuineness of the input event. Then the system gives a question to a system user about the uncertain event satisfaction that is needed for inspection in the backward inference process. Thus the system user answers the question or inquires the purpose of the question and the system shows the purpose of the question to the user. When the result of the inference is obtained, this result is outputted. When a sentence of explanation is required for the result of the inference and the system is kept under a user mode, the sentence of explanation is contracted into a base and used by means of only a rule containing an EXPLAIN part having an extraction tree.
