As for analysis of inexact information such as human behavior, mental process, social structure and so on, we consider fuzzy graph of some relation in these problems. Fuzzy graph is constructed with clusters of some levels. Furthermore, recently Uesu and Shinkai et. al [6] - [8] proposed a rational method to decide the optimal level of fuzzy clustering with partition tree. In this paper we improve their methods to use AIC (Akaike's information criterion) which is a likelihood estimator via Kulback-Leibler information number.
