摘要：Web mining is to discover and extract useful information. In the internet era web applications are increasing at enormous speed and the web users are increasing at exponential speed. As number of users grows, web site publishers are having increasing their information for attracting and satisfying users. it is possible to trace the users' essence and interactions with web applications through web server log file and Web log file contains on ly (.txt) file. The data stored in the web log file consist of large amount of eroded, incomplete, and unnecessary information. Because of large amount of irrelevant data's available in the web log file, an original log file cannot be directly used in the web usage mining. So preprocessing technique is applied to improve the quality and efficiency of a web log file. Different techniques are applied in preprocessing that is data cleaning, data fusion, data integration. In this paper we will survey different preprocessing technique to identify the issues in web log file and to improve web usage mining preprocessing for pattern mining and analysis
