基于数据仓库的Web日志挖掘技术研究

Study of web log mining based on data warehousing

Web日志挖掘是目前Web挖掘研究的一个重点。针对Web日志挖掘中存在的问题,给出了基于数据仓库技术的Web日志挖掘方案,就数据预处理、数据立方体设计及数据挖掘技术的应用进行了较为深入的探讨。并以一个Web站点日志为例,详细阐述了Web日志数据预处理、Web日志立方体设计以及数据挖掘算法的实现过程,并实现了一个Web日志多维数据集,能够有效解决Web日志分析中的难题。

Web log mining is one focus of web mining at present. As concerning the problems of web log mining, one plan based data warehousing is presented, data preprocessing, data cube and data mining algorithms are also discussed. At last web log filtering, multidimensional web log data cube construction is analyzed in detail, as well as on-line analytical processing and data mining techniques are realized though web log from web site.
