Abstract

In the context of web mining, clustering could be used to cluster similar click-streams to determine learning behaviours in the case of e-learning, or general site access behaviours in e-commerce. Most of the algorithms presented in the literature to deal with clustering web sessions treat sessions as sets of visited pages within a time period and don't consider the sequence of the click-stream visitation. This has a significant consequence when comparingsimilarities between web sessions. We propose in this paper a new algorithm based on sequence alignment to measure similarities between web sessions where sessions arechronologically ordered sequences of page accesses.
