论文摘要
不流行是由在线信息过多引起的一种新兴现象。这种信息的扩散使公众很难将可信赖的新闻和可靠的信息与不信任的网站和不可限制的来源区分开来。随着涉嫌传播不良血症的爆发，不良血症的危险首次亮相，爆发了Covid-19的大流行和机器人（即由一组算法控制的自动化帐户）。尽管先前的研究表明，机器人在重大政治事件中传播错误信息方面起着核心作用，但在不知不觉中，机器人的表现尚不清楚。在本文中，我们研究了BOT在Covid-19的Infodepic中的作用，以及不可限制的信息的扩散，例如“ 5G”和“ Bill Gates”阴谋论和与“ Trump”和“ Who”有关的“ 5G”和“ WHO”，通过分析转发网络和转推项目。我们展示了其转发网络的隔离拓扑，这表明右翼的自我媒体帐户和阴谋理论家可能会导致这种观点的裂解，而恶意的机器人可能有利于放大不可限制的信息的扩散。尽管信息扩散的基本影响可能比机器人大，但在不良情况下，机器人的影响不可忽略。
An infodemic is an emerging phenomenon caused by an overabundance of information online. This proliferation of information makes it difficult for the public to distinguish trustworthy news and credible information from untrustworthy sites and non-credible sources. The perils of an infodemic debuted with the outbreak of the COVID-19 pandemic and bots (i.e., automated accounts controlled by a set of algorithms) that are suspected of spreading the infodemic. Although previous research has revealed that bots played a central role in spreading misinformation during major political events, how bots behaved during the infodemic is unclear. In this paper, we examined the roles of bots in the case of the COVID-19 infodemic and the diffusion of non-credible information such as "5G" and "Bill Gates" conspiracy theories and content related to "Trump" and "WHO" by analyzing retweet networks and retweeted items. We show the segregated topology of their retweet networks, which indicates that right-wing self-media accounts and conspiracy theorists may lead to this opinion cleavage, while malicious bots might favor amplification of the diffusion of non-credible information. Although the basic influence of information diffusion could be larger in human users than bots, the effects of bots are non-negligible under an infodemic situation.
