虚假新闻传播事件中提升社交媒体群体互动质量的博弈研究

A Game Study on Improving the Quality of User Group Interaction in the Spread of Fake News of Social Media

[目的/意义]为了发挥用户群体互动在抑制社交媒体平台虚假新闻传播时的关键性作用,有效刻画用户群体信息行为与社交媒体平台功能设计之间的复杂关系。[方法/过程]通过建立社交媒体平台与用户群体之间的演化博弈模型,并提出审核和激励机制,运用Matlab软件对其功能效果进行模拟仿真。[结果/结论]结果显示:社交媒体平台可通过设置一定力度的审核和激励机制提高群体互动的质量,并且审核机制的力度和准确性、高质量群体互动的额外成本、奖惩措施的力度等因素对审核和激励机制的作用效果有着重要影响。

[Purpose/Significance]The purpose of this paper is to play the key role of user group interaction in suppressing the spread of fake news on social media platform,and effectively depict the complex relationship between user group information behavior and social media platform function design.[Method/Process]This paper proposes an audit and incentive mechanism of social media platform by establishing an evolutionary game model between the social media platform and the user community,and then simulates the functional effects of this mechanism by using Matlab software.[Result/Conclusion]The results show that the social media platform can improve the quality of group interaction by setting audit and incentive mechanisms within a certain range.Factors including the range and accuracy of this mechanism,the additional cost of high-quality group interaction,the intensity of rewards and punishments have important impacts on the effectiveness of this audit and incentive mechanism.
