Web usage mining itself can be classified further depending on the kind of usage data considered: Web Server Data: The user logs are collected by the Web server.
Content mining is used to examine data collected by search engines and Web spider s. Mining means extracting something useful or valuable from a baser substance, such as mining gold from the earth. Studies related to work  are concerned with two areas: constraint-based data mining algorithms applied in Web Usage Mining and developed software tools systems.
These factors have prompted researchers to develop more intelligent tools for information retrievalsuch as intelligent web agentsas well as to extend database and data mining techniques to provide a higher level of organization for semi-structured data available on the web.

They can increase profitability by target pricing based on the profiles created. Please check the box if you want to proceed. The name of this algorithm is given by Google-founder Larry Page. The collected data is being made anonymous so that, the obtained data and the obtained patterns cannot be traced back to an individual. According to the type of web structural data, web structure mining can be divided into two kinds: Extracting patterns from hyperlinks in the web: a hyperlink is a structural component that connects the web page to a different location. Mining means extracting something useful or valuable from a baser substance, such as mining gold from the earth. The usual evaluative merits are classification accuracy , precision and recall and information score. I agree to my information being processed by TechTarget and its Partners to contact me via phone, email, or other means regarding information relevant to my professional interests. The general algorithm is to construct an evaluating function to evaluate the features. You have exceeded the maximum character limit. More benefits of web usage mining, particularly in the area of personalization , are outlined in specific frameworks such as the Probabilistic Latent Semantic Analysis model, which offer additional features to the user behavior and access pattern. Application Level Data: New kinds of events can be defined in an application, and logging can be turned on for them thus generating histories of these specially defined events.
For the semi-structured data, all the works utilize the HTML structures inside the documents and some utilized the hyperlink structure between the documents for document representation.
