摘要:
 随着网络技术的不断发展,在线社交网络已经成为大众交互观点,抒发意见的主流平台.通过建立谣言扩散模型,研究社交网络中的谣言传播机制,为控制谣言传播提供指导和帮助.社交网络中,用户行为决策受其自身利益影响,因此,结合网络博弈论,给出用户在社交网络中选择传播谣言或不传播谣言的概率表达式.在此基础上,分析谣言在社交网络中的传播过程,结合用户可随时改变自身决策的行为特点,建立谣言扩散模型.并分别基于无标度网络和小世界网络,进行数值仿真,分析用户决策转换比例对谣言扩散的影响.实验结果表明,用户决策转换比例中的固有影响因子与时间速率因子对谣言在网络中的扩散具有显著影响,随着决策转换比例的减小,谣言扩散速率与最终扩散规模将出现不同程度的减小.同时,当风险主导程度足够小时,无论其如何变化,谣言必定扩散至整个网络,相反地,对于足够大的风险主导程度,谣言将无法在网络中传播.
Abstract:
 With the continual development of network technology,the online social network has become an important platform for people to express views and interact with each other.In view of this,a rumor diffusion model has been formulated and the rumor dissemination mechanism has been studied to give guidance and help to control the spread of rumors.Human behave in online social network,having an inclination to spread information so as to gain reputation or money etc.Therefore,a probability of an individual’s choice of spreading rumors or not has been proposed on the basis of game theory.The processes of rumor diffusion and the behavior characteristics have been taken into consideration to establish a rumor diffusion model in online social networks.Simulations on both scale-free network and small-world network have been conducted to investigate the impact of rate at which an individual revises his action on rumor diffusion.Its results indicate that small rate at which an individual revises his action on rumor diffusion can cut down the diffusion of gossip in varying degrees and that when the degree of risk dominance is small enough,the rumors would be spread to the entire network,no matter how it changes.
