网络社交社区中的信息传播因其最大的应用价值而引起了人们的极大关注。尽管人们已经研究了多个个体层面的扩散数据,但对信息的传播模式仍缺乏详细的了解。通过比较博客社区中的信息流和社会链接,我们发现博客社区的传播过程是由三种不同的传播机制引起的:社会传播、自我推广和广播。虽然许多以前的研究采用流行病传播模型来模拟信息扩散,我们观察到,这样的模型无法再现现实的扩散模式。在用户行为方面,我们发现大多数用户会坚持一种特定的扩散机制。此外,我们的观察表明,社会传播不仅是至关重要的扩散树的结构,而且能够诱导更多的后续个人获得的信息。我们的研究结果为社会系统中的信息传播建模提供了新的方向,并可以为基于用户行为的有效传播策略的设计提供信息。
Information spreading in online social communities has attracted tremendous attention due to its utmost practical values in applications. Despite that several individual-level diffusion data have been investigated, we still lack the detailed understanding of the spreading pattern of information. Here, by comparing information flows and social links in a blog community, we find that the diffusion processes are induced by three different spreading mechanisms: social spreading, self-promotion and broadcast. Although numerous previous studies have employed epidemic spreading models to simulate information diffusion, we observe that such models fail to reproduce the realistic diffusion pattern. In respect to users behaviors, strikingly, we find that most users would stick to one specific diffusion mechanism. Moreover, our observations indicate that the social spreading is not only crucial for the structure of diffusion trees, but also capable of inducing more subsequent individuals to acquire the information. Our findings suggest new directions for modeling of information diffusion in social systems, and could inform design of efficient propagation strategies based on users behaviors.
