Method and system for intelligent retrieval of series public security cases

Abstract

The invention discloses a method and a system for intelligent retrieval of series public security cases. The method comprises the steps of obtaining case retrieval information and extracting characteristics from the case retrieval information, respectively, to form a multi-dimensional case characteristic vector group, calculating the coefficient of association of the multi-dimensional case characteristic vector group and the multi-dimensional historical case characteristic vector group of each historical public security case in a public security case database, and outputting the information of the public security cases of which the coefficients of association exceed a preset coefficient threshold of association. According to the method for intelligent retrieval of series public security cases, the serial-parallel analysis of the series cases can be executed quickly and the efficiency is improved, and therefore, the public security organization or the investigation personnel can be helped to quickly detect cases.

Description

technical field [0001] The invention relates to the technical field of retrieval of public security cases, in particular to an intelligent retrieval method and system for serial public security cases. Background technique [0002] Serial cases refer to cases in which the same criminal subject commits multiple crimes in succession. Judging from the crime statistics in recent years, the proportion of serial cases in the entire public security cases is increasing year by year, and their social harm is becoming more and more serious. It's getting serious. [0003] Generally speaking, the development of serial cases has a certain regularity, especially the later the serial cases develop, the more serious the nature of the cases, the more cruel the perpetrators' methods of committing crimes, and the less awareness of anti-investigation of the perpetrators. The stronger it is, the greater its criminal hazards will be. Therefore, if the public security organs or other investigativ...
