Data Preprocessing in Web Log Mining Based on User Access Tree
基于用户访问树的Web日志挖掘数据预处理

Data preprocessing is the basis of the whole process of data mining in Web log mining,which directly influen-ces the quality of the Web log mining and its result.A method of data preprocessing in Web log mining based on the user access tree was proposed.The user access tree was created according to the Web logs in the preprocessing and it was used to identify the user and transaction.So the preprocessing can be worked well without the site topology.
