Training method and device for text similarity recognition model, and related equipment

Abstract

The invention relates to the technical field of text recognition in artificial intelligence, and provides a training method and device for a text similarity recognition model, and related equipment, and the method comprises the steps: obtaining a plurality of first sample groups comprising a first text sample and a second text sample; taking an element of which the literal similarity with the first text sample reaches a preset threshold value as a third text sample; labeling the third text sample to obtain a negative text sample, and forming a plurality of second sample groups; representing the samples in each second sample group with representation vectors; calculating a first similarity and a second similarity; and according to the first similarity and the second similarity, adjusting the parameters, and repeatedly obtaining the representation vector to the step to obtain a trained text similarity recognition model. Through the implementation of the text similarity recognition methodand device, the problem that in the prior art, a text similarity recognition method is low in recognition accuracy can be solved. Meanwhile, the invention also relates to a blockchain technology, andthe first sample group and the second sample group can be stored in the blockchain node.

Description

technical field [0001] The invention relates to the technical field of text recognition in artificial intelligence, in particular to a training method, device and related equipment for a text similarity recognition model. Background technique [0002] In recent years, with the continuous development of information technology, the amount of information generated has shown an explosive growth trend. In order to better analyze and process the application of this information, various algorithms and models are usually used to calculate the similarity of this information. In order to facilitate the retrieval query to obtain the target information. For example, in the process of information retrieval query, it is generally necessary to calculate the similarity between texts to obtain the target text. [0003] At present, in order to be able to calculate the similarity between texts, the similarity between texts is generally calculated through various similarity calculation algorit...
