A Method to Measure User Influence in Social Network Based on Process Log

Social network is a graph composed by actors and relationships between these actors. In the workflow management systems, there are a large number of logs which record the activity related information during process execution. The executors´ relationships between these activities can be considered as a kind of social relations to establish the corresponding social network models. In this paper, we summarize up four different kinds of social network models based on the characteristics of process logs. Then we propose a user influence measure method to better understand the organization structure of the company. Finally, we use our method to analyze the situation based on practical process logs of a company. Our method gives us a new perspective to analyze organization structure from workflow process logs.
