基于时间引用的会话构造方法研究

A Method of Session Construction Based on Time-and-reference Heuristic

Web使用挖掘是将数据挖掘和WWW这两个领域中的多种技术和方法结合起来的热门研究课题。Web使用挖掘中,数据预处理是基础、挖掘访问模式是核心、模式分析与显示是目的。在数据预处理阶段,结合时间启发方式和引用启发方式提出了时间引用启发方式的会话构造方法。该方法不仅利用了用户会话的时间特性,而且考虑了用户的浏览特性。

Web usage mining is a popular research topic which combines various technologies and methods between data mining and WWW. It is that the data pretreatment is the foundation, the mining access pattern is the core, and the pattern analysis and demonstration is a goal in Web usage mining. In the procedure of data pretreatment, time-and-reference heuristic method is uses toconstrnct session, the method which is time-based heuristic and reference-based heuristic. The method not only uses the time characteristic of session between user session and Web sites, but also considers the users navigating characteristic.
