A Statistical Machine Translation Method Fused with Translation Memory and Phrase Translation Model

Abstract

The invention discloses a statistics machine translation method integrating translation memory and a phrase translation model. The statistics machine translation method comprises a first step of utilizing a training set to obtain bilingual phrase segmentation sentence pairs; a second step of obtaining corresponding translation memory phrase pairs in the translation memory according to the obtained bilingual phrase segmentation sentence pairs, and extracting relevant characteristics of the translation memory phrase pairs; and a third step of integrating the phrase translation model and the extracted relevant characteristics of the translation memory phrase pairs, and finally obtaining target translation results of current to-be-translated sentences. The statistics machine translation method is a method which can be used for fully and appropriately digging information provided by the translation memory on the basis of a traditional phrase translation model so as to improve statistics machine translation quality.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a statistical machine translation method integrating translation memory and a phrase-based translation model. Background technique [0002] Statistical machine translation is a technology that automatically learns translation rules from bilingual parallel corpora and effectively uses these translation rules to automatically translate sentences to be translated. Statistical machine translation mainly includes word-based models, phrase-based models and translation models based on syntax tree structures. Among them, the phrase-based translation model and the syntactic tree-based machine translation model are the current mainstream methods of machine translation. [0003] After more than two decades of development, statistical machine translation has made great progress, and the quality of translation has been continuously improved. Between some special language...

Problems solved by technology

However, the reference translation given by the translation memory software is the translation of the sentence most similar to the sentence to be translated, not the direct translation of the sentence to be translated, and it needs to be manually modified

Therefore, translation memory software can only be used as an auxiliary translation tool for professional translation, and cannot be used as an automatic translation system alone
