开放教育中基于语义网格的网上学习平台

开放教育中教学资源数量大,课程文档、视频、试题库、课件资源和老师信息等教学资源分散在不同的地方。资源具有分布性、动态性、异构性等特征使得资源的分配和调度变得相当复杂。文章介绍了基于语义网格技术的网上学习平台,并给出基于语义的分布式基础结构,以达到网上学习数据资源的共享目的。通过可用技术的整合,尤其使用语义网格、协作工具、个性化和知识管理技术,来改进一个点对点的网上学习基础结构。

Semantic Grid-based E-Learning Platform for Open Education

Open education is a shared environment.Its educational resources,such as course documents,videos,test-bases,courseware,and teacher information etc.,are geographically distributed.However,the management of the resources in the shared environment is complex as the resources are heterogeneous and dynamic.In this paper,the Semantic Grid-based E-leaning platform and infrastructure for E-learning data sharing are introduced.It also discusses how to improve the end to end online learning infrastructure through the technology interaction,especially through the semantic grid,collaborative tools,personalized technology and knowledge management.
