The identification technique of cognitive structure system using subjective similarity ratings

Abstract

The PAC analysis is technique to estimate cognitive structure system using subjective similarity ratings and its hierarchical cluster analysis. However, that method cannot include one item in two groups. A wide common concept item will be included in either one cluster. Therefore I suggested a new method to form a cluster by overlap permission. I developed a support tool(PC software) and really applied it. The new method provided abstract concepts that ware equal to normal method.
