Interpretable legal judgment prediction method and device, electronic equipment and storage medium

Abstract

The invention relates to the field of natural language processing, in particular to cross application of judicial and artificial intelligence technologies, and provides an interpretable legal judgmentprediction method and device based on a court trial copulation mechanism, electronic equipment and a storage medium. The method comprises the steps of obtaining legal instrument text information to be processed; analyzing and processing the legal document text information to be processed through a concept tree classifier and a multi-classifier, and outputting a first legal judgment prediction result and a second legal judgment prediction result; if the two prediction results are consistent, accepting the current prediction result; if not, starting a court trial congruence mechanism; and through a plurality of arbitration tree classifiers, performing voting analysis processing on the second prediction result information, and determining a final prediction result according to the principlethat a small number obeys a majority. The interpretable legal judgment prediction method and device, the electronic equipment and the storage medium not only have interpretability from features to concept levels, but also further improve classification accuracy on the basis of an original model through a correction mechanism.

Description

technical field [0001] The invention belongs to the field of natural language processing, especially relates to the cross-application of judicial and artificial intelligence technology, and proposes an interpretable legal judgment prediction method, device, electronic equipment and storage medium based on the collegiate mechanism of court hearing. Background technique [0002] In the judicial field, artificial intelligence systems can not only effectively provide legal assistance to legal workers, but also quickly and effectively solve some legal problems encountered in daily life for ordinary people. While the artificial legal system serves ordinary people, its role in popularizing the law can improve the legal literacy of citizens, which in turn is conducive to maintaining social order. [0003] The goal of legal judgment prediction (Legal Judgment Prediction) is to predict the outcome of the judgment based on the factual part of the legal document. This technology is a ve...

AI Technical Summary

Problems solved by technology

The legal judgment prediction task is obviously unacceptable to the "black box" model, and the unexplainable black box model conflicts with the core characteristic of law (rigority)

This is why although the current deep learning model has achieved good results in legal tasks, many experts in the judicial field still cannot accept these methods.
