Collaborative filtering is one of the most successful applications in the field of personalized service.The Web log can provide personalized service technology with important data resource.And the validity of collaborative filtering algorithm and the quality of personalized service will be improved as long as the effective preprocessing to log data has been done.On the foundation of dealing with material log data,it gives a structure figure and a method of data preprocessing based on collaborative filtering.This method can not only provide cleaner and more regular data source but also make up the defects of former interests measurement in the aspect of user's interests measurement,which provides a more precious sustainment for collaborative filtering algorithm.
