语义网格环境下的资源协同学习平台研究

Research of Resources Collaborative Learning Platform on Semantic Grid Environment

网格计算技术为构建支持动态、开放、群体行为的跨组织大规模协作提供了良好的技术和环境支撑。在分析了语义网格相关的元数据描述、本体服务的基础上，构建了基于语义网格的教育资源协同平台体系结构，通过网格中间件技术和基于消息的发布/订阅（Pub/Sub）机制提供协同消息的发送和接收，实现协作支持服务功能，使用户获得真正所需要的资源。

Grid computing technology provides good technical and environmental support to build dynamic， open group-oriented， cross-organizational and large-scale collaboration of group behavior. After analyzing the semantic grid-related meta-data description， ontology service， the paper built educational resources collaborative platform architecture based on the semantic grid. Through using the grid middleware technology and publish/subscribe (Pub/Sub) mechanism based on message， the platform provides services about send and receive messages to achieve collaborative support services， enabling users to obtain real resources needed.
