摘要

It has become well known that knowledge about key network members is essential for monitoring public opinion and controlling rumor propagation effectively in online social networks. According to global topology of online social network and coritivity theory, a coritivity-based method for finding key nodes in online social networks is proposed in this paper. In this method, the core of online social network is firstly found out, and then the importance of each node in core set is computed by using the traditional node importance measurement method so that further distinguish the importance of each node. Experimental results show that the method can discovery the key nodes in networks accurately, which is effective and feasible.
