在线社交网络中信息与行为并发传播的社会影响

Social Influence in the Concurrent Diffusion of Information and Behaviors in Online Social Networks

Kang Zhao, Shiyao Wang, Ion B. Vasi, Qi Zhang

摘要:

在线社交网络的出现极大地促进了信息和行为的传播。虽然这两个传播过程往往是相互交织的,但“说的话”并不一定意味着“走的话”-那些分享有关行动的信息的人可能实际上并没有参与其中。我们不知道信息和行为的传播是否相似,或者社会影响在这些过程中是否扮演着同样重要的角色。本研究综合文本挖掘、社会网络分析和生存分析等方法,考察了Twitter上与冰桶挑战相关的信息和行为的并发传播。我们发现,这两个过程遵循不同的模式。单方面的社会影响力有助于信息的传播,但不扩散的行为;双边的影响力传递通过通信过程是一个显着的和积极的预测行为的扩散,但不是信息。这些结果对社会影响、社交网络和传染的理论具有启示意义。

英文摘要:

The emergence of online social networks has greatly facilitated the diffusion of information and behaviors. While the two diffusion processes are often intertwined, "talking the talk" does not necessarily mean "walking the talk"--those who share information about an action may not actually participate in it. We do not know if the diffusion of information and behaviors are similar, or if social influence plays an equally important role in these processes. Integrating text mining, social network analyses, and survival analysis, this research examines the concurrent spread of information and behaviors related to the Ice Bucket Challenge on Twitter. We show that the two processes follow different patterns. Unilateral social influence contributes to the diffusion of information, but not to the diffusion of behaviors; bilateral influence conveyed via the communication process is a significant and positive predictor of the diffusion of behaviors, but not of information. These results have implications for theories of social influence, social networks, and contagion.
