| 摘 要： | 目的/意义]研究虚拟知识社区的社会网络结构特征及影响因素，通过全面描述虚拟知识社区的人际关系网络结构，揭示影响网络形成的社会化过程。方法/过程]以知乎网"疫苗"话题为样本，基于用户关注关系构建人际关系网络，使用指数随机图模型从纯结构效应和行动者-关系效应两个方面论述社会网络的主要构局和网络形成原因。结果/结论]发现网络存在自组织，其中聚敛性、扩张性、传递性闭合和一般传递性是正向显著的，而2-路径效应为负显著。用户层面知识贡献程度表现出显著的趋异性，用户声望和知识贡献具有显著的接收者效应。

| Abstract: | Purpose/significance] This paper discussed the social network structure and influencing factors of the virtual knowledge community. Method/process] Taking the topic of "vaccine" in Zhihu.com as an example, the author established a network of the interpersonal relationship, and used the exponential random graph model to discuss the main structure and the influencing factors from two aspects: the network self-organization and the actor-relationship effect. Result/conclusion] It is found that the effects including Alt-in-star, Alt-out-star, AT-T, AT-TDU and 2-path are significant. The divergent effects of users' knowledge contribution is significant, so is the receiver effect of users' reputation and contribution. |
