Usage Guided Clustering of Web Pages with the Median Self Organizing Map

Abstract

Abstract. Web Usage Mining aims at improving Web sites thanks to the analysis of the behavior of their users. This paper proposes to cluster webpagesofawebsitethankstousagedata.Inbigwebsites,clustering individual pages is not possible, therefore the proposed method is based on a prior clustering of pages that uses semantic information about the site, such as its organization on the server. Then usage based dissimilarities between prior clusters is defined and an adaptation of the Self Organization Map to such data is used to provide visualization and clustering of groups of pages of the site. The method is illustrated on the web site of INRIA. 1
