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.
