摘要:

信息过载对网络社交媒体用户行为的抑制作用,会影响网络会话信息传播的人群层面特征。我们引入了一个机械的,基于代理的信息过载模型,并研究了信息过载阈值和信息丢失率对观察到的在线现象的影响。我们发现,会话量和参与度最低的高信息过载阈值和中档率的信息丢失。通过对Twitter上用户响应数据的校正,我们复制并解释了几个观察到的现象:1)在高信息丢失率下,响应对信息过载阈值敏感; 2)信息过载阈值和信息丢失率是帕累托最优的,当每小时超过30条通知时,用户可能会经历过载; 3)具有适度全球流行度的小级联的本地丰富性和具有高全球流行度的较大级联的本地稀缺性解释了为什么过载用户接收但不响应大的、高度流行的级联; 5)过度接触信息会通过超载用户来抑制响应的可能性,这与生物启发的病毒传播的类比相反。用信息过载的机制重新认识信息传播,可以更丰富地表示在线对话动态,从而更深入地了解信息是如何通过社交媒体传播的。

英文摘要:

The inhibiting effects of information overload on the behavior of online social media users, can affect the population-level characteristics of information dissemination through online conversations. We introduce a mechanistic, agent-based model of information overload and investigate the effects of information overload threshold and rate of information loss on observed online phenomena. We find that conversation volume and participation are lowest under high information overload thresholds and mid-range rates of information loss. Calibrating the model to user responsiveness data on Twitter, we replicate and explain several observed phenomena: 1) Responsiveness is sensitive to information overload threshold at high rates of information loss; 2) Information overload threshold and rate of information loss are Pareto-optimal and users may experience overload at inflows exceeding 30 notifications per hour; 3) Local abundance of small cascades of modest global popularity and local scarcity of larger cascades of high global popularity explains why overloaded users receive, but do not respond to large, highly popular cascades; 4) Users typically work with 7 notifications per hour; 5) Over-exposure to information can suppress the likelihood of response by overloading users, contrary to analogies to biologically-inspired viral spread. Reconceptualizing information spread with the mechanisms of information overload creates a richer representation of online conversation dynamics, enabling a deeper understanding of how (dis)information is transmitted over social media.
