Abstract

The invention provides a method and a device for evaluating importance of complex network nodes. The method comprises the following steps: acquiring local topology information and global position information of each node in a complex network to be evaluated; fusing the local topology information and the global position information of each node to obtain the quality of each node in the complex network; obtaining structural hole characteristics of the complex network, and obtaining a correction function of each node according to the structural hole characteristics; and evaluating and calculating the importance of each node according to the quality of each node and a gravitation model corrected by using the correction function, and obtaining an importance ranking list of the complex network according to the importance. According to the method, the importance degrees of the nodes in the complex network can be evaluated and sorted more accurately and effectively, important nodes can be found effectively, and the adaptability is high.

Description

technical field [0001] The invention belongs to the technical field of network analysis, and in particular relates to a method and device for evaluating the importance of complex network nodes. Background technique [0002] The importance ranking of network nodes is the focus and hotspot of research in the field of network science. Designing an algorithm that can quickly and accurately identify key nodes in the network is of great significance in both theoretical research and life practice. For example, for a virus spreading network, selectively controlling some important nodes in the network or changing its structural properties, such as vaccination, edge reconnection or vulnerability repair, etc., can effectively reduce the spread of the virus and reduce the spread; In the military supply chain network, finding key nodes and carrying out key protection can improve the reliability and efficiency of material support and effectively complete logistical support tasks; in soci...
