We propose and study a message diffusion network model of IM system with local-world preferential connections and acquaintance introduction mechanisms, which exist in IM system. We put forward the algorithms to generate the message diffusion network model and through simulation results we talk about the topological properties of this network. The topological properties such as degree distribution,...
We propose and study an evolving network model for instant messaging system (IMS) with local-world preferential connections and acquaintance introduction mechanisms, which exist in many physical complex networks especially in IMS evolving network. We put forward the algorithms to generate IMS evolving network model and through simulation results we talk about the topological properties of the IMS...
The development of blog presents characters of social networks. According to the analyses of networks of friends and visitors in blog communities, the density and centrality are very low. Blog doesnpsilat present apparent trends of centrality. There are many isolated members in blog communities. So currently blog is still merely a platform for Web logging.
