Method and device for inferring decision result of legal document based on logic rules

Abstract

The invention discloses a method and device for inferring a decision result of a legal document based on logic rules, and relates to the field of judicature. According to the method, key contents areextracted from the decision document and segmented into semantic fragments according to semantics, events are extracted from the semantic fragments and indicated into event units, according to a contextual relationship, each event unit is correlated to form an event logic atlas, and a logic atlas generation model is learned. Weights of each rule are calculated according to the winning frequency ofeach logic rule. Aiming at a new file, the event logic atlas is generated by using the generation model, and the decision result is automatically inferred according to the weights of each logic in the logic atlas. According to the method, key elements and an internal logical relationship of a case are presented in a visualized manner by a generated event logic atlas, the logic thinking manner ofa judge dealing with cases is converted into the logic rules to predetermine a result, and the evaluation of a litigation outcome, the selection of a reconciliation manner and the like of litigants oftwo sides are convenient.

Description

technical field [0001] The invention relates to the field of judicial judgments, in particular to a method and device for inferring legal document judgment results based on logical rules. Background technique [0002] In the judicial field, after the appellant submits the litigation materials, the appellant hopes to infer the outcome of the lawsuit based on the submitted materials and the judgment of similar cases in the historical materials. Traditional methods mainly include the following: 1) use keyword matching to search for similar cases. This method has low search precision, and the search results are either too few (the keyword is not included in the historical documents, but contain synonyms and near synonyms), or too many (improper keyword selection). For the retrieved documents, the result of the current case can only be roughly inferred, and the judgment result cannot be accurately deduced from the logic of legal judgment; It cannot be applied to the ever-changi...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a method and device for inferring legal document judgment results based on logical rules, using the knowledge in the legal field, and according to the learned features of historical documents, to form event Logic map to infer the possible results of new legal documents, so as to solve the problem that the existing methods only rely on keyword search and ignore legal expertise and judicial logic, resulting in the inability to infer the results of judicial cases
