Our hypothesis is that a segmentation of rare words into appropriate subword units is suffi- cient to allow for the neural translation network to learn transparent translations, and to general- ize this knowledge to translate and produce unseen words.2We provide empirical support for this hy- Arabic–Chinese Neural Machine Translation: Romanized Arabic as Subword Unit for Arabic-sourced Translation Abstract: Morphologically rich and complex languages such as Arabic, pose a major challenge to neural machine translation (NMT) due to the large number of rare words and the inability of NMT to translate them. In neural machine translation (NMT), it has become standard to translate using subword units to allow for an open vocabulary and improve accuracy on infrequent words. ���p��$�V{����ٹ�g��n!\2/dž��d;��#�i��6�fBk���iY�6���݀[�+@6~ؖ j,�:4C= �r In this paper, we introduce a simpler and more effective approach, making the NMT model capable of open-vocabulary translation by encoding rare and unknown words … 1.
