摘要
【目的/意义】为了探究复杂网络中信息的传播机制以及不同网络中的信息推动力。【方法/过程】本文利用邻居节点特性与信息公信力确定传播规则,探究了小世界与无标度网络中的信息传播,并研究了节点对爆发规模的影响差异。【结果/结论】结果发现:无标度网络中信息传播的驱动力倾向于从众效应,而小世界网络则主要源于信息本身;不同k-shell值的节点对无标度网络爆发规模的影响比小世界网络显著;不同度值的节点对二者的爆发规模影响均显著。
[Purpose/significance] In order to investigate the information spreading mechanism in complex network and the driving forces in different networks. [ Method/process ] Propagation rules are determined by characteristics of neighbors and information credibility to explore the diffusion mechanism in small-world network and scale-free network . And then the influence of different types of nodes on outbreak size is studied respectively. [ Result/conclusion]The results show that： the driving force of information spreading in the scale free network tends to be the conformity effect, while the information spreading in the small world network is mainly due to the credibility of the information. Nodes with different k-shell values have more significant effects on outbreak size than small-world network. Nodes with different degree values have significant effects on outbreak size in both two networks.
