社会信息网络结构和规模演变研究

The Study of Social Information Networks and the Evolution of Their Scales

利用复杂网络及网络节点和边的属性,研究了100多年来社会信息网络结构和规模的演变及信息传播的变迁。首先讨论了社会信息网络发展中出现的增长性、突变性、集群效应、马太效应等特征,以及不同阶段的网络拓扑结构;然后研究了不同阶段的网络信息容量,再利用信息在网络中的传播规律,研究了社会信息网络和民众的兴趣是如何相互影响的,最后展望了社会信息网络可能的发展方向。

In this article,using complex network theory and the attributes of edges and nodes of network,we investigate the evolution of structure and scale of social information network and changes of information dissemination in more than one hundred years.Firstly,the characteristics in the development of social information network,such as growth,mutation,cluster effect,Matthew effect and so on,are discussed,and topology structures of networks at different development stages of social information network are investigated.Secondly,information capacities of networks at different development stages are studied and how information in network dissemination influence person's interest is investigated using information propagation laws in networks.Finally,we forecast possible development directions of social information network.
