Research and development in Web usage mining system-key issues and proposed solutions: a survey

Web mining can be classified into three domains: Web structure mining, Web content mining and Web usage mining. There are generally three tasks in Web usage mining: preprocessing, knowledge discovery and pattern analysis. Though Web usage mining is still ranged in the application of traditional data mining techniques, in view of changes in application environment and data concerned, some new difficulties have arisen accordingly. The paper takes efforts to address such challenges in the three phases and introduces some proposed solutions simultaneously.
