Abstract

The present invention discloses a clustering technology-based criminal case association string method, comprising the following steps: S1, obtaining high-dimensional and heterogeneous data type case data variables related to the case association string analysis; S2, according to the case Data variables establish a similarity model describing the degree of case correlation, and calculate a similarity matrix based on the similarity model; S3. Use graph decomposition technology to decompose a graph converted from a similarity matrix into several connected subgraphs; S4. Connect connected subgraphs Use a clustering algorithm for graph cutting calculations to accurately group all cases; S5, extract key feature parameters of each case group, and push the key feature parameters to users according to their priority. The invention can not only process the data with definite and unique characteristics of source data, but also process the data with only possibility characteristics, which greatly improves the efficiency of correlation stringing and merging of criminal cases, and has high accuracy.

Description

technical field [0001] The present invention relates to the technical field of investigation and case solving, in particular to a clustering technology-based method and system for correlating and merging criminal cases. Background technique [0002] The serial and parallel correlation analysis of gang-type and serial crime cases is an important part of the criminal case law enforcement department's investigation and case-solving work. By analyzing and extracting common points between multiple cases and connecting key information, law enforcement agencies can broaden their investigation horizons; combining series of cases for investigation can significantly reduce law enforcement costs, increase the depth and breadth of crime fighting, and enhance overall work efficiency. [0003] With the development of informatization in the whole society, criminal law enforcement agencies have established a computer management system for criminal cases and accumulated a large amount of cri...
