Web Mining

 

Web mining is the application of data mining or other information process techniques to WWW, to find useful patterns. People can take advantage of these patterns to access WWW more efficiently. Web mining can be divided into three categories: content mining, usage mining, and structure mining.

Web Content Mining

Web content mining is an automatic process that extracts patterns from on-line information, such as the HTML files, images, or E-mails, and it already goes beyond only keyword extraction or some simple statistics of words and phrases in documents.

Web Structure Mining

Web structure mining is a research field focused on using the analysis of the link structure of the web, and one of its purposes is to identify more preferable documents. The intuition is that a hyperlink from document A to document B implies that the author of document A thinks document B contains worthwhile information.

Web Usage Mining

Web servers record and accumulate data about user interactions whenever requests for resources are received. Analyzing the web access logs of different web sites can help understand the user behavior and the web structure, thereby improving the design of this colossal collection of resources.
