Target-Side Context for Discriminative Models in Statistical Machine Translation
Table 2: BLEU scores obtained on the WMT14 test set. We report the performance of the baseline, the source-context model and the full model.
['data size', 'small', 'medium', 'full']
Statistically significant differences (α=0.01) are marked in bold. The source-context model does not help in the small data setting but brings a substantial improvement of 0.7-0.8 BLEU points for the medium and full data settings, which is an encouraging result.
