摘要:

自动译后编辑(APE)研究的最新方法表明,多源模型可以获得更好的结果,该模型联合编码源(src)和机器翻译输出(mt)以产生译后编辑句子(pe)。沿着这一趋势,我们提出了一个新的多源APE模型的基础上的Transformer。为了构建有效的联合表示,我们的模型内部学习将src上下文纳入mt表示。通过这种方法,我们实现了一个显着的改善基线系统,以及国家的最先进的多源APE模型。此外,为了证明我们的模型将src上下文的能力,我们表明,未知的MT系统的字对齐成功地捕获在我们的编码结果。

英文摘要:

Recent approaches to the Automatic Post-Editing (APE) research have shown that better results are obtained by multi-source models, which jointly encode both source (src) and machine translation output (mt) to produce post-edited sentence (pe). Along this trend, we present a new multi-source APE model based on the Transformer. To construct effective joint representations, our model internally learns to incorporate src context into mt representation. With this approach, we achieve a significant improvement over baseline systems, as well as the state-of-the-art multi-source APE model. Moreover, to demonstrate the capability of our model to incorporate src context, we show that the word alignment of the unknown MT system is successfully captured in our encoding results.
