Discovering classification rules [Han 1993 , Weiss 1991] allows one to develop a profile of items belonging to a particular group according to their common attributes. This profile can then be used to classify new data items that are added to the database.

In Web Mining, classified techniques allow one to develop a profile for clients who access particular server files based on demographic information available on those clients, or based on their navigation patterns. For example, classification on Web access logs may lead to the discovery of relationships such as the following:

  • clients from state or government agencies who visit the site tend to be interested in the page /company/product;

  • 50% of clients who placed an online order in /company/product2, were in the 20-25 age group and lived on the West Coast.
