- Identifying the influential users on social network is a critical problem for advertising, promotion, public opinion analysis and network security. A few empirical studies have verified that some users could lead to wider spreading and promote the information diffusion prominently. However, the existing studies limited by a single layer analysis for information diffusion, there is still lack of a multifaceted analysis method for identifying influential nodes. In this paper, we propose a novel method for identifying the influential users in the topology of information diffusion, which contains a three-tier analytical mechanism: information-level analysis, relationship-level analysis and community-level analysis. This three-tier analytical mechanism can upgrade information-level to relationship-level, and finally identifying the influential nodes in relationship-level. The experiments on Sina Weibo demonstrate that 0.3% of users who span structural holes control 28% of the information diffusion in each event and can cause the secondary-wave of information diffusion. When the information diffuses to users with higher pagerank, more users will participate in the information diffusion.
