A hybrid system for concept-based web usage mining

A web site should be easy to browse by visitors. However, sometimes the reality is quite different. Situations like several unrelated topics in a single web page may lead to confusion and make harder to reach the information that the visitors are looking for. The design of the whole site (interface, content, structure, usability, etc.) is one of the most important aspects for any institution that wants to survive in the cyberspace.
