Central Author Mining from Co-authorship Network

Most researches on co-authorship network analyze the author´s information globally according to the overall network topology structure, instead of analyzing the author´s local network. Therefore, this paper presents a community mining algorithm and divides big co-authorship network into small communities, in which entities´ relationship is closer. Then we mine central authors in community by three different centrality standards including closeness centrality, eigenvector centrality and a new proposed measure termed extensity degree centrality. We choose the SIGMOD data as datasets and measure the centrality from different views. And experiments in co-authorship network achieve many interesting results, which indicate our technique is efficient and feasible, and also have reference value for scientific evaluation.
