Abstract

The invention discloses a translation method. The method comprises the following steps: taking a source language statement and a target language statement corresponding to the source language statement as training samples, and training to generate a first translation model; inputting the source language statement into a first translation model to obtain a translation result of the source language statement; comparing the translation result with a corresponding target language statement to determine a mistranslation fragment in the translation result and a corresponding mistranslation source fragment; and training the first translation model to generate a second translation model by taking the source language statement containing the mistranslation source fragment and the target language statement corresponding to the source language statement as training samples and taking reduction of the generation probability of the mistranslation fragment as a training target. The invention also discloses a corresponding device.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a translation method and device. Background technique [0002] The current neural machine translation (Neural Machine Translation, NMT) system can translate sentences similar to human language, but the current neural machine translation model training method pays more attention to the overall quality of the generated translation sentences, making the sentences translated by the model very difficult. Fluency, low accuracy, and frequent mistranslations, that is, the semantics of the translation result deviates from the semantics of the input sentence to be translated. [0003] In order to improve the accuracy of the translation model, the current common practice is to collect mistranslated sentences during the application process of the translation model, manually correct the mistranslated sentences, and then add the corrected sentences to the training s...
