Sensor-equipped mobile devices have allowed users to participate in various social networking services while they are on the go. We focus on proximity-based mobile social networking environments where users share information obtained from different places via their mobile devices when they are in proximity. Since people are more likely to share information if they can benefit from the sharing or if...
The increasing popularity of social networks improves information sharing among different users. Most existing online social networks involve the client/server architecture where each user needs to access to a server for contents sharing with other users. In this paper, we focus on constructing a mobile peer-to-peer based social network. We propose an efficient mobile social network to facilitate...
We propose a new measurement called geographic community, which provides a bridge between spatial proximity and the social nature of individuals in mobile social network. A novel approach for detecting these geographic communities has been proposed. Through developing a spatial proximity matrix, an improved symmetric nonnegative matrix factorization method (SNMF) is used for detecting these geographic...
Inspired by recent empirical research on link communities, we borrow some important ideas and concepts for our own research to provide a more reasonable computation model of transitive trust. The key advantages of using link community methodology is to reflect on the nature of the social network features of Hierarchy and Overlap. Our research mainly resolves the computation of trust transitivity in...
