We have studied the structures and applications of fuzzy graphs. Related this study, we introduced one methodology, Fuzzy Core Index Analysis. By virtue of this method, we can transform the nodes of a fuzzy graph with a semi-ordered structure into a linear-ordered structure. It should be noted that this method decides a unique ordering (with respect to the importance) of the nodes of a fuzzy graph. The procedure for this method, however, was somewhat complicated in instruction structure analysis. In this paper, we then define fuzzy core indices directly from a contingency table and investigate the validity of the redefinition.
