社交网络中激进化的一种规范性方法

A normative approach to radicalization in social networks

Vincent Bouttier, Salomé Leclercq, Renaud Jardri, Sophie Deneve

AI总结:

本研究提出基于循环信念传播的规范性方法,证明降低消息相关性可避免社交网络中的激进化与极化,并利用Facebook和Twitter数据验证其有效性。

摘要:

近几十年来,在线社交联系的大众化使得信息在几秒钟内即可全球获取。不幸的是,这伴随着极端观点的急剧增加,且目前尚无明确的解决方案。我们使用一种通过节点间消息交换在大规模环状图中执行概率推断的模型,展示了社交图中的循环性如何直接导致激进化与观点极化。我们证明,如果能够降低传入消息之间的相关性,这些有害效应是可以避免的。该方法基于信念传播(BP)的一种扩展,称为循环信念传播(CBP),该扩展可被训练以显著改进循环图中的推断。CBP 使用来自 Facebook 和 Twitter 的数据进行了基准测试。该方法可能启发新的方法,以防止错误信息在网上的病毒式传播与放大,提升社交网络在全球范围内分享知识的能力,而无需诉诸审查。

英文摘要:

In recent decades, the massification of online social connections has made information globally accessible in a matter of seconds. Unfortunately, this has been accompanied by a dramatic surge in extreme opinions, without a clear solution in sight. Using a model performing probabilistic inference in large-scale loopy graphs through exchange of messages between nodes, we show how circularity in the social graph directly leads to radicalization and the polarization of opinions. We demonstrate that these detrimental effects could be avoided if the correlations between incoming messages could be decreased. This approach is based on an extension of Belief Propagation (BP) named Circular Belief Propagation (CBP) that can be trained to drastically improve inference within a cyclic graph. CBP was benchmarked using data from Facebook and Twitter. This approach could inspire new methods for preventing the viral spreading and amplification of misinformation online, improving the capacity of social networks to share knowledge globally without resorting to censorship.
