Comprehensive influence evaluation algorithm of complex network nodes based on global-local attributes
Published 2022-09-01“…Mining key nodes in the network plays a great role in the evolution of information dissemination, virus marketing, and public opinion control, etc.The identification of key nodes can effectively help to control network attacks, detect financial risks, suppress the spread of viruses diseases and rumors, and prevent terrorist attacks.In order to break through the limitations of existing node influence assessment methods with high algorithmic complexity and low accuracy, as well as one-sided perspective of assessing the intrinsic action mechanism of evaluation metrics, a comprehensive influence (CI) assessment algorithm for identifying critical nodes was proposed, which simultaneously processes the local and global topology of the network to perform node importance.The global attributes in the algorithm consider the information entropy of neighboring nodes and the shortest distance nodes between nodes to represent the local attributes of nodes, and the weight ratio of global and local attributes was adjusted by a parameter.By using the SIR (susceptible infected recovered) model and Kendall correlation coefficient as evaluation criteria, experimental analysis on real-world networks of different scales shows that the proposed method is superior to some well-known heuristic algorithms such as betweenness centrality (BC), closeness centrality (CC), gravity index centrality(GIC), and global structure model (GSM), and has better ranking monotonicity, more stable metric results, more adaptable to network topologies, and is applicable to most of the real networks with different structure of real networks.…”

Node characteristic and propagation model in microblog forwarding network
Published 2016-01-01“…Microblog is an important social network with rapid propagation speed and great influence.The network influence is determined by users' node characteristic.Nodes' degree and propagation model in microblog forwarding network were investgated.Firstly,microblog forwarding network was constructed through distinguishing information flow direction.Secondly,the mean and variance of out-degree and in-degree were discussed.The difference between out-degree and in-degree was clarified.Finally,the simulation shows that the direction characteristic of edge has significantly influence on information propagation.The propagation becomes harder and propagation range diminishes while percolation threshold rises in directed graph under the same probability.…”
