[PDF] Top 20 CUNI System for WMT17 Automatic Post Editing Task

... All data-driven approaches to MT suffer in qual- ity when translating rare words (including words not seen during training at all) and NMT is no ex- ception. In out neural approach to APE, we would still like our APE ... See full document

... It has become quite common for human translators to use machine translation (MT) as a first step, and then to manually post-edit the translation hypoth- esis. This can result in a significant gain of time, ... See full document
