摘要

[目的] 分析在信任和权威两种心理机制作用下, 舆论与社会网络结构的协同演化规律。[方法] 采用相对协议模型表达舆论交互机制, 并设计信任和权威的心理计算模型, 通过计算机模拟信任和权威影响下舆论和网络结构的协同演化过程。[结果] 动态网络的情景下, 舆论的一致性不如静态网络, 个体之间更容易因观点偏好的差异形成非正式的局部团体; 个体间的信任值呈现幂律分布, 但是权威个体并不一定拥有高信任关系。[局限] 认知心理的可计算模型以参数传递的方式嵌入舆论模型, 二者的协同方式有待进一步改进。[结论] 信任与权威对舆论与社会网络间的协同演化有显著的影响, 控制权威个体的观点偏好, 能在一定程度上改变群体的舆论发展方向。

Abstract：

[Objective] Study on co-evolution rules of social networks and public opinion considering the effects of trust and authority. [Methods] Design a computational model of trust and authority, express interactive mechanism of public opinion by relative agreement model, then analyse the co-evolving process of dynamic social networks and public opinion based on computational experiment. [Results] The experiment results show that the consistency of public opinion in the scenario of dynamic social networks is lower than the static networks, and the informal groups are easier to form. The trust values follow the power-law distribution, but it is not sure that the authoritative individuals hold high trust friendship. [Limitations] The cognitive computational models are embedded into the opinion model through parameter passing, and the synergistic mode between them needs to be improved. [Conclusions] Trust and authority influence the co-evolution process significantly; the organization should control the authoritative individuals to guide the direction of public opinion.
