Influence Accessment Algorithms of Regional Influential Nodes in Online Social Networks

Based on the online social network analysis,from a regional perspective,we research micro-process of information diffusion.By the measuring the real behavior of the user's sharing and reading,we construct the network of information diffusion.We found that a small group of nodes can cover the most of the communication behavior of the information diffusion.Then,we proposed a recognition algorithm InfluenceRank to find them,and verify the effectiveness.
