Abstract

The present disclosure provides a legal question answering method and device based on weakly supervised learning and a joint learning mechanism. The method includes: obtaining legal issues input by users; using a pre-built multi-label classification model and a preset set of legal labels to classify the legal issues based on a joint learning mechanism to obtain the legal labels of the legal issues; Retrieving candidate legal question-answer pairs associated with the legal label from the legal question-answer pair database; outputting an answer from at least one of the candidate legal question-answer pairs as an answer to the legal question. The legal question-and-answer method and equipment based on weakly supervised learning and joint learning mechanism provided by this disclosure provides a set of intelligent question-and-answer methods for legal consultation for colloquial questioning methods, which improves the traditional methods that cannot recognize and understand colloquialism well. Legal issues and the flaws in their precise classification of intent.

Description

technical field [0001] The invention relates to the field of artificial intelligence technology, in particular to a legal question answering method and device based on weakly supervised learning and joint learning mechanism. Background technique [0002] With the continuous development of my country's economy and society, the people's awareness of democracy and legal system has gradually increased, and the demand for legal consultation has also increased. Due to the shortage of resources of lawyers and professional legal practitioners, many inquiries cannot be answered in a timely and accurate manner. The application of artificial intelligence in the legal field provides a feasible solution to the imbalance between supply and demand in the legal consulting market. [0003] In the process of legal consultation, the parties mostly make legal questions about legal issues through oral expressions, which often do not contain relevant legal professional vocabulary. The tradition...
