ファジィクラスター分析と応用(人間科学セッションその1)

抄録

We often use fuzzy graph to analyze inexact information such as sociometric structure, instruction/ cognition sequence, opinion poll and so on. Concerning the hierarchical cluster analysis of a fuzzy graph, it is interesting how to decide the optimal cutting level as to a partition tree. In this paper, we would not only propose the decision method, but also illustrate the typical cluster analysis methods in multivariate analysis and its evaluation method. Then, we proceed to explain the practical effectiveness through the sociometry analysis.
