Abstract: Web has been growing as a dominant platform for retrieving information and discovering knowledge from web data. Web data is stored in web server log files. Web usage analysis or web usage mining or web log mining or click stream analysis is the process of extracting useful knowledge from web server logs, database logs, user queries, client side cookies and user profiles in order to analyze web users’ behavior. Web usage analysis requires data abstraction for pattern discovery. This data abstraction can be achieved through data preprocessing. This paper presents different formats of web server log files and how web server log data is preprocesses for web usage analysis.
Keywords: Web Server Logs, Web Usage Analysis, Preprocessing, Data Cleaning, User Identification, Session Identification, Path Completion, Pattern Discovery, Pattern Analysis.
