PURPOSE:To improve the substitution processing efficiency of the slot value by providing a facet into a slot to limit the possible slot value and succeeding also the value of the relevant facet at the time of the slot succession. CONSTITUTION:Many knowledges expressed in a frame model are stored in a knowledge base 1 and each frame includes the attributes of the knowledges and concepts in the relevant frame together with the slots showing the relations with other frames. In addition, an expectation facet is set into the slot to prescribe the possible value of the relevant slot. When a slot value substitution function is carried out, a knowledge base control part 2 carries out said substitution only when the slot value to be substituted is equal to a partial gathering of the facet value. When the slot is succeeded, the expectation facet is succeeded in response to the value of the inheritance roll described in a succession origin slot.
