为了解决在构建统计机器翻译系统过程中所面临的双语平行数据缺乏的问题,该文提出了一种新的基于中介语的翻译方法,称为Transfer-Triangulation方法。该方法可以在基于中介语的翻译过程中,结合传统的Transfer方法和Triangulation方法的优点,利用解码中介语短语的方法改进短语表。该文方法是在使用英语作为中介语的德-汉翻译任务中进行评价的。实验结果表明,相比于传统的基于中介语方法的基线系统,该方法显著提高了翻译性能。
This paper presents a transfer-triangulation method for pivot-based translation between two languages with poor bilingual data.It takes the best of both typical transfer method and triangulation method for pivot-based translation,and decodes pivot phrases to improve phrase table.Evaluated on German-Chinese translation task with English as the pivot language,results show that our method achieves significant improvement over baseline pivotbased methods.
