[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.
