Abstract
An inference system provided with a first knowledge base for storing general knowledge which is a theorem, and a second knowledge base for storing associative knowledge which is different in knowledge structure from the above mentioned general knowledge. The associative knowledge is automatically generated from the comparison between a first proof tree where inferences have ended in failure and a second proof tree where inferences have ended in success, if inferences have ended in success by the help of information about a suggestion appended additionally when the first inferences of a problem stopped, and the associative knowledge generated will be stored in the second knowledge base thereafter. The associative knowledge includes a if-part which describes the conditions to be focused on a then-part which includes the description of the relation between the above mentioned condition to be focused on and the other additional conditions to be associated with and the description of the information holding on the basis of the above-mentioned relation.
