社会网络中基于Agent的意见形成模型:社会心理学视角

Agent-based opinion formation modeling in social network: a perspective of social psychology

Xicheng Yin, Hongwei Wang, Pei Yin, Hengmin Zhu

摘要:

以往关于意见建模的研究大多缺乏对个体心理活动和群体行为的同步研究。本文从社会学和心理学的角度出发,以态度改变理论、群体行为理论和进化博弈理论为基础,提出了一个基于Agent的网络舆论形成模型。在该模型中,影响说服过程的因素有三个,即领导者的可信度、受众的特征和群体环境。该模型被应用到Twitter的主题类型,参数变化,意见领袖的意见形成的影响进行了分析。实验结果表明,争议话题的意见演化具有较大的不确定性和可持续性。收益成本比对意见形成有显著影响,适度的收益成本比将导致最长的松弛时间或最统一的全球意见。此外,拥有大量粉丝的名人比专家更有能力影响公众舆论。本文丰富了舆论形成模型的研究内容,为企业的公共关系管理和市场预测提供了理论依据。

英文摘要:

Most previous works on opinion modeling lack the simultaneous study of individual mental activity and group behavior. This paper is motivated to propose an agent-based online opinion formation model based on attitude change theory, group behavior theory and evolutionary game theory in the perspective of sociology and psychology. In this model, there are three factors influencing the persuasion process, including credibility of the leaders, characteristic of the recipient, and group environment. The proposed model is applied to Twitter to analyze the influence of topic type, parameter changing, and opinion leaders on opinion formation. Experimental results show that the opinion evolution of controversial topic shows greater uncertainty and sustainability. The ratio of benefit to cost has a significant impact on opinion formation and a moderate ratio will result in the longest relaxation time or most unified global opinions. Furthermore, celebrities with a large number of followers are more capable of influencing public opinion than experts. This paper enriches the researches on opinion formation modeling, and the results provide managerial insights for business on public relations and market prediction.
