Problems solved by technology

[0005] The error correction effect of the actual error correction model is largely affected by the quality and quantity of the training samples. The higher the quality of the training samples, the greater the number of training samples, the better the error correction effect of the error correction model is. worse

Abstract

The embodiment of the invention provides a corpus generation method and device and computer equipment. According to the embodiment of the invention, the method comprises the steps: obtaining a positive sample in a target domain, and determining a replacement word corresponding to at least one correct word in the positive sample; and replacing the at least one correct word with the corresponding replacement word, obtaining a negative sample corresponding to the positive sample, and generating a first error correction parallel corpus of the target domain at least based on the positive sample andthe negative sample. According to the embodiment of the invention, a large number of high-quality first error correction parallel corpora in the target field can be further quickly obtained.

Description

Technical field[0001]The embodiments of this application relate to the field of network technology, and in particular to a method and device for generating corpus, and a computer device.Background technique[0002]With the rapid development of Internet technology, users are increasingly making purchases through online shopping malls. When a user searches for a desired product, he generally needs to enter the text information of the product to be searched in the search box of the user terminal, and the user terminal performs a product search based on the text information and displays the product matching the text information to the user.[0003]However, when the user enters the text information of the product to be searched, due to the limitation of knowledge or hand errors during the input process, there may be incorrect text input. In order to improve the user experience, the user can search and correct the wrong text information entered by the user. The correct text information that m...
