Abstract

The invention discloses a model building method and system, a paragraph label obtaining method and a medium, and relates to the field of natural language processing transfer learning, and the method comprises the steps: collecting all judgment document data from a database, and obtaining pre-training data; defining paragraph labels of different types of judgment documents; marking paragraph labels of different types of judgment documents to obtain training data; constructing a judgment document structured model; pre-training the model; training a pre-trained judgment document structured model by utilizing the training data; and debugging the trained judgment document structured model to obtain a final judgment document structured model, wherein the input of the judgment document structured model is judgment document text data, a task prefix is added to a paragraph of the input judgment document, and the output of the judgment document structured model is paragraph label text data of the judgment document. The model established by adopting the method can predict any type of judgment document paragraph label after being trained.

Description

technical field

[0001] The present invention relates to the field of natural language processing transfer learning, in particular, to a method and system for establishing a structured model of adjudication documents, and a method and medium for obtaining paragraph tags of adjudication documents. Background technique

[0002] As of December 2019, more than 80 million judgments have been published online, providing massive data resources for the practice and research of legal artificial intelligence.

[0003] Judgment documents are judicial products that record the process of judicial trial activities and clarify the rights and obligations of the parties. They are important resources for studying legal text information and provide important data for legal artificial intelligence application research such as recommendation of similar cases based on judgment documents, prediction of judgment results, and intelligent question-and-answer. element index. However, the judgment docu...
