Abstract :
This paper introduces the calculation method of degree centrality, closeness centrality and betwenness centrality based on the Sina weibo user data of Fudan University in Dec, 2012. The cumulative probability distribution of each centrality indicator is measured and analyzed. The relationship among three centrality metrics is also discussed. It is concluded that the combination of the three centrality measurements may effectively discover important nodes in the microblog network.
