共同进化网络中的意见和社区形成

Opinion and community formation in coevolving networks

Gerardo Iñiguez, János Kertész, Kimmo K. Kaski, R. A. Barrio

摘要:

在人类社会中,意见的形成是由社会互动介导的,因此发生在关系网络上,同时影响网络的结构及其演变。为了研究这种意见和社会互动结构的共同进化,我们开发了一个动态的基于代理的网络模型,考虑到短距离的相互作用,如个人之间的讨论,长距离的相互作用,如个人的态度调制的整体情绪的感觉,和外部场对应的外部影响。此外,个人偏见也可以自然地考虑在内。此外,该模型包括意见依赖的链路重布线计划来描述网络拓扑结构的协同演化与一个更慢的时间尺度比意见形成。利用该模型进行了全面的数值模拟和平均场计算,它们表明了快速和慢速时间尺度之间的分离的重要性,从而导致网络组织为具有相同意见的连接良好的小社区代理。

英文摘要:

In human societies opinion formation is mediated by social interactions, consequently taking place on a network of relationships and at the same time influencing the structure of the network and its evolution. To investigate this coevolution of opinions and social interaction structure we develop a dynamic agent-based network model, by taking into account short range interactions like discussions between individuals, long range interactions like a sense for overall mood modulated by the attitudes of individuals, and external field corresponding to outside influence. Moreover, individual biases can be naturally taken into account. In addition the model includes the opinion dependent link-rewiring scheme to describe network topology coevolution with a slower time scale than that of the opinion formation. With this model comprehensive numerical simulations and mean field calculations have been carried out and they show the importance of the separation between fast and slow time scales resulting in the network to organize as well-connected small communities of agents with the same opinion.
