摘　　要：[目的]分析与测算微信群成员之间的隐性关系及其强度,并与显性关系相结合得到全关系以完善微信群内部社会网络刻画。[方法]以微信趣缘群为例,研究群成员之间基于话题的合作共现并将其作为隐性关系的测量指标,借鉴Salton指数计算关系强度。分析成员的话题讨论参与情况和隐性关系分布,对比显性关系网络和全关系网络。[结果]话题讨论情况可以清晰反映群成员的亲疏关系;与成立目的有关的话题讨论有助于经营和维护成员关系。[局限]对群成员的讨论参与度和话题贡献度有进一步详细测量的优化空间。[结论]综合显性关系与隐性关系的全关系网络对微信群内部关系网络结构的刻画相较于显性关系更加全面,且能够揭示出更丰富的信息。[Objective] This paper analyzes the implicit relationship among WeChat group members and meaures its strength, which is also combined with their explicit relatinship to describe the social network characteristics of WeChat groups. [Methods] First, we collected chatting records from one WeChat interest group. Then, we used the co-occurrence to measure the implicit relationship and the salton index to calculate their strength. Third, we analyzed the discussion participation to explore the implicit-relationship distribution. Finally, we compared the full-relationship network with explicit-relationship network. [Results] We found that topic discussion clearly reflected relationship among group members. Posting more relevant topics helps to manage and maintain membership. [Limitations] More research is needed to measure goup members’ engagement. [Conclusions] The full-network with implicit and explicit relationship reveals more insights on the structure of WeChat group.
