Conceptual difference is a serious problem in group knowledge acquisition systems, especially when different people with different background participate in a group. In our former research, each a peace of knowledge held by people is expressed by a single decision tree, and conceptual difference is detected by checking the difference. Sometimes it occurs that the attributes and the values with conceptual difference do not appear in decision trees and fails to detect conceptual difference. In this paper, we propose a method to solve this problem by using decision trees with diverse structures which are produced by our genetic algorithm.
