Based on collaborative information filtering and information aggregation services, the social news website carries out a collective gatekeeping function, supplying an empirical ground to test the bandwagon effect on information diffusion. Modeling the interpersonal effect and bandwagon effect in collective gatekeeping with threshold models, we confirm the bandwagon effect of collective gatekeeping on news diffusion with two novel datasets. The results demonstrate that the bandwagon of collective gatekeepers is the primary driver for online news diffusion. Interestingly, the bandwagon effect of collective gatekeeping is moderated by the strength of interpersonal effects. The theoretical generalizations of this research contribute to our understanding about the impact of collective gatekeeping on information diffusion.

基于协作信息过滤和信息聚合服务，社交新闻网站执行集体关守功能，为测试潮流对信息传播的影响提供了经验基础。使用阈值模型对集体关守中的人际效应和潮流效应进行建模，我们使用两个新的数据集来确认集体关守对新闻传播的潮流效应。结果表明，集体看门人的潮流是在线新闻传播的主要动力。有趣的是，集体关守的潮流效应被人际效应的强度所缓和。这项研究的理论概括有助于我们了解集体关守对信息传播的影响。
