【Abstract】 A new fuzzy clustering algorithm of Web session is presented. We define the notion of a ”user session” and a new distance measure between two web sessions. The objective function is based on selecting c representative objects from the data set in such a way that the total fuzzy dissimilarity within each cluster is minimized. We also present a improved fuzzy clustering algorithm. A comparison between the two algorithms shows improved fuzzy clustering algorithm is more efficient.更多还原
