A semantic session analysis method partitioning Web usage logs is presented.Semantic W eb usage log preparation model enhances usage logs with semantic.The M arkov chain mode1 based on ontology semantic measurement is used to identi. ing which active session a request should belong to.The corn— petitive method is applied to determine the end of the sessions. Compared with other algorithms,more successfu1 sessions are additionally detected by semantic outlier analysis.

The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity. The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions.However.there are many shortcomings in traditiona1 measurements.This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page.Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e币cient.
