| Abstract(in English) | A new data mining method named Matrix Clustering is proposed for CRM (Customer Relationship Managemnt). Matrix clustering is defined to generate a dense sub-matrix from a sparse binary matrix by exchanging rows and columns. We also propose a new fast algorithm named ping-pong algorithm for clustering large sparse matrix. The ping-pong algorithm is 1, 000 to 10, 000 times faster than a naive algorithm. This algorithm is applied to WWW access log analysis, and can find valuable relationshops between users and their accessed URL's.. |
