Abstract

The invention discloses a criminal suspect comprehensive influence evaluation method based on social network analysis. The method includes: firstly, constructing a crime network based on social network analysis; secondly, extracting a criminal suspect influence primary evaluation index in the crime network; then, determining the weight of the centrality index by adopting an entropy method; finally, determining the weight of the criminal suspect intermediate centrality evaluation index and the weight of the criminal suspect influence intermediate time factor evaluation index through an entropyevaluation method, obtaining a criminal suspect comprehensive influence evaluation index, and ranking the comprehensive influence of the criminal suspect comprehensive influence evaluation index. According to the method, the problem that the influence evaluation of a single centrality index of an existing social network on network nodes is single and one-sided is solved, three centrality indexes are more comprehensively considered, and two time influence factors of a crime network are innovatively added, so that the influence evaluation of criminal suspects in the crime network is more comprehensive, reasonable and scientific.

Description

technical field [0001] The invention relates to the field of public security, in particular to a method for evaluating the influence of a criminal suspect, in particular to a method for evaluating the comprehensive influence of a criminal suspect based on social network analysis. Background technique [0002] In the field of public security research, multiple property crimes such as theft, fraud, snatching, and robbery have a large number of cases and a wide range of harm, and are closely related to the lives of the masses; become one of the important threats to social stability. The academic community has also paid great attention to the characteristic analysis and prevention of such crimes. [0003] According to the number of criminal members and their behavioral relationship, there are various forms of criminal organization, such as individual crime, joint crime, gang crime and criminal group. Among them, in gang crimes, criminal suspects are mostly gathered by blood, f...
