基于语义P2P虚拟学习社区的构建方法

Building Peer to Peer virtual learning community based on semantic

随着系统规模的扩大,在基于P2P远程学习系统中出现学习参与者无法有效发现学习资源,同时建立的虚拟学习社区不能很好地反映参与者的动态学习特性。在分析语义网和本体建模的基础上,按照学习社区要求建立节点本体模型,提出一种基于混合模式P2P技术的远程学习系统;并在此基础上,设计实现基于语义相似度的虚拟学习社区的构建算法。

With the size of distance learning system expanding based on P2P technical, the marner can not efficiently discover resource in system and building virtual learning community can not reflect the learner＇ s dynamic attribute in fact. This paper analyzes semantic network and ontology modeling, creates ontology model of peers according to building learning community. A distance learning system based on mixed-mode P2P is designed. A algorithm building virtual community based on semantic similarity is designed and implemented in this system.
