一种复杂网络上信息传播的动态竞争机制

Competition Dynamics of Information Propagation on Complex Network

非共识性的意见普遍存在于人类的交互活动中。本文研究由带有反对意见的信息诱导出的信息竞争动态过程。建立一个新的信息竞争模型,以体现复杂网络中消息交互的真实情况。结果显示,对网络中节点进行k-shell分类后发现,节点的k-shell值在信息竞争过程中起到了重要作用。通过变换模型中的参数,可以成功解释不同的信息竞争现象。新的信息竞争模型非常适用于对网络信息传播的研究。

The ＂non-consensus＂ opinions pervade all patterns of human＇ s interactive activities. This paper studies the phenome- non of the information competition dynamics induced by messages with opposite meaning. We construct a new information compe- tition model which could perfectly match the reality on complex networks. It is shown that the k-shell value of nodes plays an im- portant role in reflecting its competitive power in the information competition processes, after classifying the nodes on the network with the k-shell decomposition technique. By varying the variables in the model, different cases of information competition phe- nomena can be successfully explained. This new information competition model should be useful to the study on network informa- tion dissemination.
