Research Abstract	A methodology which extract an effective information from data with complicated structure or distribution was proposed in this study. The proposed method is based on graph-representation which express a subset of data as a node and a relationship between subsets as a edge. The proposed method was applied to some real data sets. As a result, the method can represent the characteristics of data effectively. It is expected that the learning performance or recognition rate of classification problem is improved and that we find a clue to elucidate the network structure of data with dependencies among them.
