A Model of Close-Relationship among Mobile Users on Mobile Social Network

A smart-phone generates lots of contextual information related with user environment in Social Network Service (SNS). Especially, communication data is an important context to recognize a close-relationship among mobile users. The related works using the communication data in this research area have actively studied. However, the most of the studies were to analyze social network studying on a personal distance or to measure centrality of mobile communication network. Therefore, we propose a model of close-relationship among mobile users on mobile social network. This proposed model can measure closeness between a user and the user's acquaintances. And the model is designed with users' communication log generated among mobile devices. To realize this, we collect and analyze context data of mobile users using context-aware platform and context server.
