网络教育资源浏览的导航模型及其挖掘算法

Navigation model and mining algorithm for network education's resource browse

将Web使用挖掘应用到网络教育领域,分析了其挖掘过程,包括数据采集、数据预处理、模式发现和模式分析;通过建立网络教育资源导航模型,并利用蚁群算法对Web日志数据中使用者的浏览行为进行挖掘;提出一个新的导航路径挖掘算法,可以发现有价值的用户浏览模式,指导用户对教育资源作进一步的搜索,还可以将训练好的网络图用于用户的个性化定制服务。

Web usage mining is applied to the domain of network education, and the mining process including data collecting, data preprocessing, pattern discovering and pattern analyzing is analyzed. By constructing the Web site model for network education＇s resource and using the ant colony algorithm to mine users navigation patterns in the Web log, a new navigation paths mining algorithm is proposed. With the algorithm, valuable users navigation patterns can be found,and then network education＇s resource can be searched more efficiently. The trained network map can also be applied to user＇s individualized customization.
