在在线社交网络中定位特权传播者
Locating privileged spreaders on an Online Social Network
AI总结:
本文基于复杂网络理论,结合西班牙2011年为期一个月的政治抗议事件的拓扑与互动数据,研究在线社交网络中哪些用户具备特权信息传播能力及其原因。
摘要:
社交媒体已提供大量证据,证明其具备信息扩散能力。时尚与谣言,以及社会动荡和骚乱,都在在线社交网络(OSNs)中快速传播,并影响参与其中的很大一部分人群。这推动了大量研究,既关注社会传染背后的机制,也关注谁(如果存在的话)能够引发全系统范围的信息传播。获取关于拓扑结构(即友谊网络)和动态过程(即OSNs用户实际互动方式)的真实数据,对于解读前者如何促进后者的成功——这里的成功被理解为信息传播的效率——至关重要。借助源自复杂网络理论的定量分析,本文讨论了在信息扩散方面谁具有特权传播能力,以及为何具有这种能力。研究通过考察2011年在西班牙发生、持续一个月的一次政治抗议事件的演变来完成这一分析。
英文摘要:
Social media have provided plentiful evidence of their capacity for information diffusion. Fads and rumors, but also social unrest and riots travel fast and affect large fractions of the population participating in online social networks (OSNs). This has spurred much research regarding the mechanisms that underlie social contagion, and also who (if any) can unleash system-wide information dissemination. Access to real data, both regarding topology --the network of friendships-- and dynamics --the actual way in which OSNs users interact--, is crucial to decipher how the former facilitates the latter's success, understood as efficiency in information spreading. With the quantitative analysis that stems from complex network theory, we discuss who (and why) has privileged spreading capabilities when it comes to information diffusion. This is done considering the evolution of an episode of political protest which took place in Spain, spanning one month in 2011.
