随着信息技术的发展和e-Learning学习模式的兴起,网络上教育资源的数量在急速增长,但是学习者却往往淹没在知识的海洋中,出现认知迷航等问题。针对教育资源定位困难的问题,该文研究了教育资源的聚类组织方法,设计并实现了一个面向e-Learning的教育资源聚类系统。该系统可以将资源检索的结果按照一定的算法划分为多个子类别,并通过可视化的方式对划分的结果进行呈现,从而为学习者提供更加精确的资源导航和更为快速的资源定位。在实际使用中,系统的使用者认为,与简单返回资源列表的方式相比,图形化的资源组织与呈现方式能够更好地起到资源导航的作用。

With the development of information technology and e-Learning, the amount of online educational resources is growing rapidly. However, learners have dififculties when they use these resources. They are always submerged in the ocean of knowledge and have cognitive trek problems. Aimed at these problems, we study the educational resources organization method based on clustering. And then we design and development an educational resources clustering system oriented to e-Learning. This system can classify the resources into several clusters according to certain algorithms. And then it can visualiz...
