Design of interactive interfaces to detect conceptual difference

Conceptual difference among different people is a serious problem on a group knowledge acquisition system and a creative thinking support system in which different people are concerned. In this paper, we study conceptual difference among different people and describe a method of detecting it in the case that different symbols are used in the same meaning and/or the same symbols are used in different meanings. Conceptual difference is defined and the outline of our system is described. The detecting algorithm is designed, and then a prototype system and its evaluation is introduced.
