| Abstract: | Purpose/significance] The information exchange process in WeChat group has diversified role types, and it is of great significance to define the role types of WeChat lurkers and to analyze the causes of diving behavior to further explore the process of information exchange and grasp the inner communication mechanism of WeChat.Method/process] Based on real dialogue sample as study object, the paper calculated the members' direct participation and indirect dependence, and designed the algorithm of the rate of outlier to quantitatively identify the lurkers in the WeChat group. The lurkers' character types were divided based on time series statements, calculate the intimacy between members through interaction intensity and the fit of interest, and build the information exchange network as the weight of the side, and the behavioral motivation of lurkers was analyzed in WeChat group based on dynamic evolution of network structure.Result/conclusion] By calculating the rate of outlier and the number of time series statements, it can effectively define the lurkers and their role types in WeChat group. Based on the evolution analysis of member network embedding position, roles and so on, it is found that there is a correlation between lurkers' behaviors and membership status, topic interest, relationship between members and so on. |
