Abstract: Presently, acquisition of user browsing is one of the major topics on Web Log mining. According to the important character of user browsing, a way of applying rough set acquisition rule is presented. Important character is selected as condition properties, then through arithmetic ultimate rule was acquired, instance analysis effect turns to be well. In this way, just in virtue of simple data pretreatment, simple and effective access pattern can be obtained.

Key words: Web access pattern, Rough set, Data mining

摘要： 用户浏览模式获取是现阶段Web日志挖掘的主要目标之一。该文根据用户浏览的重要特征，提出了一种应用粗糙集理论获取规则的方法。选取重要特征作为条件属性并通过算法实现获取最终规则，实例分析效果良好。该方法的特点是只需要简单的数据预处理但可以获得简洁有效的访问模式。
