The access patterns, user profiles and other data are maintained at the servers and/or the clients. Web usage mining (WUM) deals with mining such data in order to discover meaningful patterns such as associations among the web pages and categorization of users. 4 Recent Trends in Knowledge Discovery 25 A Fig. 3. htm. WUM can be effectively utilized in commercial applications, for designing new product promotions and evaluating existing ones, determining the value of clients and predicting user behavior based on users’ profiles.

The hyperlinks contain important information which can be utilized for efficient information retrieval. 3 the information that several hyperlinks (edges) point to page A may indicate that A is an authority [76] on some topic. Again, based on the structure of the web graph, it may be possible to identify web communities [41]. A web community is described as a collection of web pages, such that each member of the collection contains many more links to other members in the community than outside it.
