为了防止非法社区成员进入社区和合法社区成员对知识社区知识资源的非法使用,构建了由用户资质、社区知识资源和综合控制策略等组成的虚拟知识社区的综合访问控制模型.利用基于属性的访问控制思想,从用户角色、用户综合信誉、用户拥有的知识货币量以及知识单价,知识交易量、知识满意度等侧面建立用户资质和社区知识资源模型,依据该模型,利用决策表,表达了虚拟知识社区的综合访问控制策略.结合案例比较结果表明了综合访问控制模型的可行和策略的有效性.

In order to prevent the non-authorized community members into the community and avoid accessing the non-authorized the community knowledge resources to the authorized community members, a composite access control model in virtual knowledge com-munity is constructed, which mainly consists of user capability, community knowledge resources, a composite access-control policy. Moreover, using attribute-based access control thoughts, user capability and communities'knowledge resources are modeled, which consist of user's role, comprehensive reputation, available knowledge currency, and knowledge exchange price, knowledge exchange quantity, knowledge satisfaction degree respectively. Based on the user capability and communities'knowledge resources models, a composite access control policy for virtual knowledge communities is provided in decision table. Case analysis demonstrated the feasi-bility of the model and the effectiveness of the composite access control policy.
