A Survey on Data Preprocessing in Web Usage Mining

Abstract

With the abundant use of Internet and constant growth of users, the World Wide Web has a huge storage of data and these data serves as an important medium for the getting information of the users access to web sites which are data stored in Web server Logs. Today people are interested in analyzing logs file as they show actual usage of web site. But the data is not accurate so preprocessing of Web log files are essential then after that data are suitable for knowledge discovery or mining tasks. Web Usage Mining, a part of Web mining and application of data mining is used for automatic discovery of patterns in clickstreams and associated data collected or generated as a result of user interactions with one or more Web Sites. This survey paper gives the literature review and also overview of various steps needed for preprocessing phase. Keywords - Data Fusion, Path Completion, Pre processing, Session Identification, Web usage, Web Server Log file.
