| 摘 要： | 目的/意义]微信群内部会话交流过程存在着复杂的网络结构，探究微信群内部网络结构特征并划分成员角色对研究微信群中信息传播及成员角色关系具有重要意义。方法/过程]以虚拟社区理论和会话分析理论为基础，以真实微信群内部的会话数据作为研究对象，通过构造成员活跃度划分微信群成员角色类型，基于成员相互回应行为与共同回应行为设计成员关联强度算法并构建会话交流网络，采用社会网络分析和内容分析方法对其静态结构特征及动态结构演化进行分析。结果/结论]微信群内部成员角色及地位具有差异性，会话交流过程呈现出明显的中心性态势；微信群会话交流网络符合六度分割理论，具有小世界效应的特征；微信群会话交流网络具有动态演化性且核心成员具有时间依赖性。

| Abstract: | Purpose/Significance] There are complex network structures in the internal session process of WeChat Group and it is of great significance to explore the characteristics of the internal network of WeChat group and to divide the members' roles in the study of the relationship between the information dissemination and the member roles in the WeChat group.Method/Process] This paper was based on the theory of virtual community and the theory of session analysis,and the conversation data within the real WeChat group was taken as the research object,by constructing membership type of WeChat group members,the membership intensity algorithm was designed based on commom response and mutual response of members,and the conversation exchange network was constructed.Social network analysis and content analysis were used to analyze its static structure and dynamic structure evolution analysis.Result/Conclusion] The roles and positions of members in WeChat group were different,and the process of conversation exchange showed a clear central tendency.The WeChat group's conversation exchange network conformed to the six-degree division theory and had the characteristics of small-world effect.The WeChat group's conversation exchange network had the characteristics of dynamic evolution core members were time-dependent. |
