Abstract

K-shell method can quickly identify influential nodes in complex networks. However, it is hard to distinguish the differences in the importance of these nodes. In addition, it underestimates the importance of high degree nodes at the edge of the network. Aiming at these two shortcomings of the K-shell method, this paper proposed an approach based on the K-shell position and neighborhood within two steps to identify influential nodes in complex networks. It refined the global position of the node according to the removal order during K-shell decomposition. Considering the local topology and global position of nodes, the proposed method identified the influential nodes based on the K-shell position of the neighborhood within two steps. To simulate the propagation process with epidemic model on eight real networks, the experiment results show that the proposed method can identify and rank the influential nodes compared with other five relative methods with better accuracy and efficiency.
