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幣cient.

This a sample Plug and Play filter driver that provides WMI data blocks. Typically, driver writers will copy the sample code into their own driver and make any minor modifications so that the WMI data blocks are always available when the driver is loaded. Alternatively, WmiSamp can be left as a filter driver if WMI data blocks should only be made available when the filter driver is loaded.
