Abstract: In complex networks, the identification of influential nodes is very important to study the transmission and control of viruses, the location of key points of network attacks, the spread of public opinion, and the marketing promotion of markets. Therefore, based on analysis of the existing algorithms for the identification of influential nodes in complex networks, this paper proposes a new method to identify influential nodes by aggregating local structure information (ALSI). This method considers two factors: the influence of the node itself and the influence contributed by the neighbor node. The degree and K-shell value of the node are introduced when calculating the influence of the node itself, and the degree and K-shell value of the neighbor node are introduced in the calculation of the influence contributed by the neighbor node. Different calculation methods are adopted according to the comparison result of the K-shell value with the node. The greater the K-shell value and the node degree are, the more important the node is. To evaluate the performance of the algorithm, the susceptible–infected–recovered (SIR) model is used to analyze and compare the running results of 9 algorithms on 8 different networks. The experimental results show that the proposed algorithm can effectively detect the influence of nodes and outperforms many state-of-the-art algorithms.
