虚拟社区成员之间的沟通交流,从知识形成的角度来看,是主题的传播。社区成员之间因为主题的交互、知识的产生而形成了基于不同主题的社会关系。对虚拟社区成员之间的社会关系进行挖掘与可视化分析,能够揭示社区内部的网络结构和动态变化,为社区成员提供更好的服务。对基于主题的虚拟社区成员社会关系进行挖掘,在此基础上设计并实现了社会关系查询与分析工具SocialQuery,对虚拟社区成员社会关系进行了可视化查询与分析。实验结果表明SocialQuery能够发现虚拟社区成员社会关系的强度和主题,所提出的社会关系计算方法优于现有方法。
The communication between the members of the virtual community is, from the perspective of knowledge formation, the transmission of the theme. Because of the interaction of the theme and the generation of knowledge, the community members formed social relations based on different themes. The excavation and visual analysis of the social relations between the members of the virtual community can reveal the network structure and dynamic changes in the community and provide better services to community members. Mining the social relations of the members of the virtual community based on the theme, on the basis of which SocialQuery, a social relationship inquiry and analysis tool, is designed and implemented, and the social relations of the members of the virtual community are visually queried and analyzed. The experimental results show that SocialQuery can find out the strength and theme of the social relations in the members of the virtual community, and the proposed social relations method is superior to the existing methods.
