ABSTRACT:
A threshold value is set in advance for each of a number of conclusions. Possibility values of conclusions obtained from an approximate reasoning apparatus are compared with the corresponding threshold values, and a conclusion whose possibility value is equal to or greater than its threshold value is outputted (displayed). When information indicative of an error is entered with regard to a conclusion whose possibility value is equal to or greater than the corresponding threshold value but which actually does not hold true, or a conclusion whose possibility value is less than the corresponding threshold value but which actually does hold true, the threshold value concerning the conclusion that has produced the error is revised dynamically. The weights of conclusions are set. By multiplying the possibility value of a conclusion from an approximate reasoning apparatus by the weight set for this conclusion, a score is calculated for every conclusion. If the order of the obtained scored differs from an order of priority devised by a human being, weight is revised in such a manner that the order of the scores will coincide with the order of priority.
