Abstract:

With the increasing popularity of social networks, social networks have become the main platform for information dissemination. The relative difficulty of regulating the content of social networks has led to some negative messages spreading easily and producing large adverse effects. The influence blocking maximization aims to find the set of nodes that need to adopt positive influence to minimize the number of nodes affected by negative messages in the process of information dissemination. To address the problem of high running time complexity of existing social network influence blocking algorithms, in this paper, we proposed an influence blocking maximization algorithm based on community detection, which first utilized the extended h-index centrality of social network nodes to select candidate seed nodes, and then used these seed nodes as the starting point to discover communities in social networks with a label propagation algorithm, followed by calculating the social network communities by of the relationship matrix and the modularity of the current relationship matrix to merge the communities, and finally, the labeling metric rank of the initial seed nodes was calculated and the top k nodes were selected as the members with the maximum blocking influence. The experimental results show that the algorithm has good blocking performance and low time complexity.
