It promotes browsing for information rather than searching for it. Web mining [Cha03,KB00,Liu06] is the extraction of interesting and potentially useful patterns and implicit information from artifacts or activity related to the World Wide Web. There are roughly three knowledge discovery domains that pertain to Web mining: Web content mining, Web structure mining, and Web usage mining. Web content mining is an automatic process that goes beyond keyword extraction [QD07] to discover useful information from the content of a Web page.
