Combining Local and Document-Level Context: The LMU Munich Neural Machine Translation System at WMT19
Dario Stojanovski, Alexander D. Fraser · 2019
We describe LMU Munich's machine translation system for English→German translation which was used to participate in the WMT19 shared task on supervised news translation.We specifically participated in the documentlevel MT track.The system used as a primary submission is a context-aware Transformer capable of both rich modeling of limited contextual information and integration of large-scale document-level context with a less rich representation.We train this model by fine-tuning a big Transformer baseline.Our experimental results show that document-level context provides for large improvements in translation quality, and adding a rich representation of the previous sentence provides a small additional gain.
