Abstract

Medoid clustering frequently gives better results than those of the K-means clustering in the sense that a unique object is the representative element of a cluster. Moreover the method of medoids can be applied to nonmetric cases such as weighted graphs that arise in analyzing SNS(Social Networking Service) networks. A general problem in clustering is that asymmetric measures of similarity or dissimilarity are difficult to handle, while relations are asymmetric, e.g., in SNS user groups. In this pa- per we consider hard and fuzzy c-medoids for asymmetric graphs in which a cluster has two different centers with outgoing directions and incoming directions. This method is applied to a small illustrative example and real data of a Twitter user network.
