| 英文摘要 | Microblogs have been widely used as a new form of online social networking. based on the user profile data collected from sina weibo, we find that the number of microblog user bidirectional friends approximately corresponds with the lognormal distribution. we then build two microblog user networks with real bidirectional relationships, both of which have not only small-world and scale-free but also some special properties, such as double power-law degree distribution, disassortative network, hierarchical and rich-club structure. moreover, by detecting the community structures of the two real networks, we find both of their community scales follow an exponential distribution. based on the empirical analysis, we present a novel evolution network model with mixed connection rules, including lognormal fitness preferential and random attachment, nearest neighbor interconnected in the same community, and global random associations in different communities. the simulation results show that our model is consistent with real network in many topology features.
