Web日志挖掘数据预处理研究

Research on Data Preprocessing in Web Log Mining

在详细介绍ELF日志文件格式的基础上定义了会话表,并对预处理过程中几个主要步骤进行深入讨论,总结已有的各种处理手段提出新的改进方法,其中重点针对会话识别进行了改进并给出了新的算法。

Based on extended log file format,the session table was defined.Through the in-depth research of several major steps in the preprocessing,existed various means have been summarized to propose a new method.Especially,a new algorithm in session identification was improved and thus presented.
