Legal case similarity distinguishing and pushing method

Abstract

The invention discloses a legal case similarity discrimination and pushing method, and the related discrimination method comprises the steps: carrying out the classification of a target legal case, and extracting historical cases of the same type from a historical case database according to the obtained case types to form a candidate set; performing event sequence representation on the target legal case and each similar historical case in the candidate set; according to the event sequence measurement model, calculating the distance between the event sequence corresponding to the target legal case and the event sequence corresponding to each historical case in the candidate set; and based on the distance of the event sequence and in combination with a scoring function, calculating the similarity between the target legal case and historical cases in the candidate set. According to the method, more comprehensive and accurate class case identification can be realized; meanwhile, the legalinstrument is expressed as a time sequence event sequence, similarity calculation is carried out on the basis of an unsupervised mode, historical cases with high scores are selected for pushing, manpower input is greatly reduced, and pushing intelligence can be better achieved.

Description

technical field [0001] The invention relates to the field of legal intelligence, in particular to a method for judging and pushing the similarity of similar legal cases. Background technique [0002] At present, the theory and technology of artificial intelligence are becoming more and more mature, and the scope of application is constantly expanding. In 2017, the national artificial intelligence strategy "New Generation Artificial Intelligence Development Plan" proposed to build smart courts, promote the application of artificial intelligence in evidence collection, case analysis, legal document reading and analysis, and realize the intelligentization of the court's judicial system and judicial ability. Among them, the realization of similar cases and similar judgments through artificial intelligence technology has become an important research content close to the needs of judges. [0003] As an auxiliary tool, similar cases and similar judgments are aimed at finding simil...
