摘　　要：针对目前国内高校精品课程答疑环节薄弱且高校之间课程资源共享利用较差的现状,提出基于网格跨校构建精品课程答疑资源的思想,各高校作为网格节点按课程采用问题—答案对的方式构建答疑资源,各节点之间基于网格技术实现答疑资源共建共享.文中给出跨校答疑资源共建共享模型、资源组织和描述及答疑流程.设计并开发基于网格的自动答疑系统,实现各节点间答疑资源共建共享.模拟系统表明,该系统能有效支持各高校节点资源共建共享.Focusing on the situations that national elaborate courses keep weak in Q/A and the sharing use of curriculum resources among universities remains poor, in this paper, we propose the idea of co-constructing Q/A resources of elaborate courses over campuses based on grid. Each university, as a grid node, can construct Q/A resources by way of the question answer couple according to the curriculum, and realizes the co-construction and sharing of Q/A resources among the nodes based on grid technology. It advances the Q/A resources co-construction and sharing model, resources organization and description, and Q/A flow. We develop the automatic Q/A system based on grid to realize Q/A resources co-construction and sharing among nodes. Results show that this system can support effec- tively resources co-construction, sharing and using among university nodes.
