Research on improving methods of preprocessing in web log mining

摘要

This paper analyzes the web logs by using data mining technology. Through structure mining, usage mining and content mining, analyzes and studies the existing problems in current mining technology. Aiming at relevant key preprocessing schedule such as Frame page filtration, time-out threshold value setting and long-time setting, etc. this paper puts forward a modified data preprocessing technical method and compares the mining results through tests before and after the modification. Experiment proves that, the modified preprocessing technology is feasible and it can solve problems existing in relevant preprocessing effectively.
