Abstract

A knowledge information extracting device includes a first storing means for storing a type of information to be output with respect to a designated information processing device, and a second storing means for storing a type of information to be input with respect to the information processing device. A knowledge information database access means is capable of accessing a knowledge information database containing a plurality of rules, each of the rules including a condition part and a conclusion part. A rile extracting means is capable of extracting at least one rule having the condition part corresponding to the type of information to be input, and the conclusion part corresponding to the type of information to be output, by using the knowledge information database access means. A knowledge information storing means is capable of storing the at least one rule extracted by the rule extracting means by associating the at least one rule with the information processing device.
