Knowledge from the Web, Using Web Usage Mining

Web usage mining differs from collaborative filtering in the fact that we are not interested in explicitly discovering user profiles but rather usage profiles. When preprocessing a log file we do not concentrate on efficient identification of unique users but rather try to identify separate user sessions. Web usage mining is used to try to extract knowledge from the raw data available on the Web by organizing web pages in well defined structures or by looking into patterns of activities of Web users. Web usage mining can be used to support dynamic structural changes of a Web site in order to suit the active user to extract the knowledge from the web.
