Abstract

The invention provides a case intelligent pushing method and system based on case semantic analysis, and the method comprises the following steps: S1, carrying out the preprocessing of a case description text of a case, which comprises word segmentation, part-of-speech tagging, and stop word removal; S2, extracting important features of the case according to the preprocessed case description textto form a feature vector of the case; And S3, associating related cases according to the feature vectors, obtaining the comprehensive similarity between the case and each related case by adopting a case feature similarity calculation method, sorting the related cases according to the similarity, and pushing the cases with high similarity. Through the method and the system provided by the invention, the workload of case analysis and manual processing can be reduced, the working cost and the time cost of police officers are greatly reduced, and the case solving efficiency is improved.

Description

technical field [0001] The invention relates to the field of police case analysis, in particular to an intelligent case push method and system based on case semantic analysis. Background technique [0002] Serial cases and combined cases (referred to as serial and combined cases) are common methods for solving series of cases, especially when the investigation of individual cases is in trouble. The analysis of parallel cases refers to the analysis of various traces and clues found in cases in different regions or at different times, to find out cases that may be committed by the same criminal subject, and to analyze the seemingly unrelated clues and physical evidence. Conduct a comprehensive analysis to find out enough evidence to lock the suspect. In today's society, with the trend of professionalization, gangs, and migration of crimes, serial cases account for a considerable proportion. Therefore, a number of different cases with internal connections are combined to disco...
