弱关系加强了社交媒体上的愤怒传染
Weak ties strengthen anger contagion in social media
摘要：
越来越多的证据表明，与面对面的交流类似，人类的情感也会在网络社交媒体中传播。然而，这种情绪传染的机制，例如，不同的感觉是否以不太可能的方式传播，或者情绪的传播如何与社交网络相关，很少被研究。事实上，由于成本高和时空的限制，探索这一主题是具有挑战性的使用传统的问卷调查或控制实验。因为它们是大量个体的自然情感反应的收集点，在线社交媒体网站为从计算社会科学的角度解决这个问题提供了一个理想的代理。在本文中，基于对微博上数百万条推文的分析，令人惊讶的是，我们发现愤怒比喜悦更容易沿着较弱的联系传播，这意味着它可以渗透到不同的社区，并摆脱当地的陷阱，因为陌生人更经常分享这些内容。通过一个简单的扩散模型，我们发现，较弱的关系加速愤怒的传播速度和覆盖率的指标。据我们所知，这是第一次提出定量的长期证据，揭示了喜悦和愤怒传播机制的差异。随着弱关系在蓬勃发展的社交媒体中的广泛扩散，我们的研究结果意味着愤怒的传染可能会大大加强，从而使其负面影响全球化。
英文摘要：
Increasing evidence suggests that, similar to face-to-face communications, human emotions also spread in online social media. However, the mechanisms underlying this emotion contagion, for example, whether different feelings spread in unlikely ways or how the spread of emotions relates to the social network, is rarely investigated. Indeed, because of high costs and spatio-temporal limitations, explorations of this topic are challenging using conventional questionnaires or controlled experiments. Because they are collection points for natural affective responses of massive individuals, online social media sites offer an ideal proxy for tackling this issue from the perspective of computational social science. In this paper, based on the analysis of millions of tweets in Weibo, surprisingly, we find that anger travels easily along weaker ties than joy, meaning that it can infiltrate different communities and break free of local traps because strangers share such content more often. Through a simple diffusion model, we reveal that weaker ties speed up anger by applying both propagation velocity and coverage metrics. To the best of our knowledge, this is the first time that quantitative long-term evidence has been presented that reveals a difference in the mechanism by which joy and anger are disseminated. With the extensive proliferation of weak ties in booming social media, our results imply that the contagion of anger could be profoundly strengthened to globalize its negative impact.
