中文摘要：

摘要针对目前科研人员知识社区用户自主参与建设不足，知识交流、协同与创新效率和效果不佳等问题，提出了基于Web2．0和云计算构建科研人员知识社区的思路。该科研人员知识社区采用web2．0和云计算的理念、架构和技术，通过云平台实现知识社区中海量知识的“云”化自组织管理及知识云的动态组合与调度，采用聚合多种Web2．0应用的云客户端实现科研人员按需多途径、多方式参与各类知识的交流与协同。基于Web2．0和云计算构建的知识社区有利于科研人员更好地自主参与知识社区建设，促进科研人员的知识交流、协同与创新。

英文摘要：

Abstract To solve problems of the lack of user participation, the weakness of the efficiency and effectiveness of knowledge exchange, cooperation and innovation in knowledge community for scientific researchers, a new approach to build knowledge community for scientific researchers （ KCfSR ） is put forward, which is based on Web2.0 and cloud computing. The new KCfSR is to use the idea, framework and technology of Web2.0 and cloud computing. In the proposed KCfSR, the cloud platform is used to achieve cloud-enabled self-organizing management of huge knowledge in knowledge community as well as dynamic combination and dispatching of knowledge cloud, and the open cloud client which converges different Web2.0 applications is used to achieve that scientific researchers participate in knowledge ex- change and cooperation on-demand with multi-approaches and multi-modes. The new knowledge community facilitates scientific re- searchers better participate in activities in knowledge community and promote knowledge exchange, cooperation and innovation among sci- entific researchers.
