Abstract

The invention provides a text matching model training method and device, equipment and a storage medium, and the method comprises the steps: obtaining a plurality of first sample pairs, each first sample pair comprises two texts and a matching result of the two texts, carrying out the mask processing of entity nouns and / or verbs contained in the texts in each first sample pair, obtaining corresponding second sample pair, performing iteration pre-training on the initial text matching model based on the second sample pair to obtain a pre-trained text matching model, obtaining a plurality of third sample pairs corresponding to the preset business scene, wherein each third sample pair comprises two texts and a matching result of the two texts, based on the third sample pairs, performing iterative fine tuning training on the pre-trained text matching model to obtain a text matching model corresponding to the preset business scene. According to the invention, text matching can be carried out more accurately.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a text matching model training method, device, equipment and storage medium. Background technique [0002] With the development of Internet technology, the intelligent dialogue system can carry out semantic recognition of user input information, determine the user's dialogue intention, and has a wide range of applications in e-commerce, smart devices, etc. Frequently Asked Questions (FAQ) dialogue system is a method commonly used in intelligent customer service. After customers enter the questions they want to inquire on the intelligent dialogue system, the intelligent dialogue system will automatically identify the semantic information of the text and return the answer. In this process, the text matching method used by the intelligent dialogue system is a key part that affects the accuracy of the entire dialogue system. [0003] At present, in the intelligent dialog...
