The embodiment of the invention provides a method and device for generating a Chinese-Thai bilingual corpus based on a multistage translation model. The method comprises the following steps: obtainingChinese original text sentences and Thai original text sentences; inputting the Chinese original text sentences into a pre-trained first two-stage translation model, outputting Thai translation sentences, inputting the Thai original text sentences into a pre-completed second two-stage translation model, and outputting Chinese translation sentences, wherein the first two-stage translation model and the second two-stage translation model are formed by jointly training high-resource Chinese-English bilingual corpora, high-resource English-Thai bilingual corpora and low-resource Chinese-Thai bilingual corpora from two translation directions. According to the embodiment of the invention, under the condition that only the Chinese-English bilingual corpus and the English-Thai bilingual corpus exist, the translation model capable of generating the Chinese-Thai bilingual corpus is obtained, and the obtained translation model is jointly trained from two translation directions through the low-resource Chinese-Thai bilingual corpus, so that the expression of the model is improved to better synthesize the corpus.
Description
technical field [0001] The present invention relates to the technical field of text translation, and more specifically, to a method and device for generating Chinese-Thai bilingual corpus based on a multi-level translation model. Background technique [0002] Training a high-quality machine translation model often requires millions of bilingual parallel corpora. However, for some bilingual language pairs with relatively scarce resources, such as Chinese and Thai bilingual corpora, the construction of machine translation models is often a big challenge. [0003] In order to solve this problem, NLP (Natural Language Processing) engineers often do data synthesis to generate more bilingual data, and then use these synthetic corpus for machine translation model training. Due to the easy availability of high-quality monolingual corpora in large quantities, current main synthesis methods are based on a large amount of monolingual corpus and a small amount of bilingual corpus.
