Abstract

The invention provides a structure centrality-based network community discovery method, which can effectively reveal inherent community structures in a complex network. A node centrality measure is proposed for locating local structure center nodes in the network according to local interaction information of nodes and global information among the nodes, and a community cluster quantity is determined; and based on an identified structure center, a complete community structure is revealed in a way of extension to the edge from the structure center by adopting a heuristic local search policy. Meanwhile, a boundary region is defined for the community structure, so that different node roles in a network community are effectively identified for revealing network group structure characteristics. A large amount of experiments prove that the method can effectively reveal the community structure in the network, is relatively high in universality and has a relatively high application value.

Description

technical field [0001] The invention belongs to the field of complex network analysis technology research. Specifically, it involves a network community discovery method based on structural centrality. Background technique [0002] A complex network is an abstract description of a complex system. Nodes in the network represent individuals in the complex system, and edges in the network represent the internal connections between individuals in the complex system. Complex network has become a broad interdisciplinary subject, involving physics, biology, social science, system science, network science and other disciplines, and has gradually become a challenging research topic to solve complex problems, and has a wide range of applications in many fields, such as Social network analysis, bioengineering, electricity and transportation, human behavior analysis, big data analysis, etc. The research and analysis of complex networks has greatly expanded the breadth and depth of peo...
