Data preprocessing plays a vital role in Data Mining. In this paper, the authors have adopted the concept of web based mining for cleansing the web server log files. Web mining extracts useful information of hypertext documents. Once a user access the web pages /sites their information are recorded in a file as an entry called log file. The web server log files are used for mining several useful patterns to analyze the access behavior of the user. Before performing the mining process the raw data has to be preprocessed in order to improve the quality of data to be mined.
