In order to make Chinese and English translation more intelligent and more reasonable, this article uses sentence-level interpretation to rewrite the translation as a translation task between the same language. In the absence of a large-scale parallel paraphrasing corpus, the machine translation results and the reference translation of the source language are used to approximate the parallel paraphrasing corpus. Then, the model is used to train a repetitive system from machine translation results to reference translations to generate semantically consistent sentence-level repetition results. Based on this, the results of restatement are introduced into the translation assumption of system integration. Finally, on the basis of translation and interpretation, the mobile application-oriented design and development were carried out to realize Chinese and English machine translation.
