Table 1: BLEU scores for EN↔TR when adding copied monolingual data.
['[BOLD] system', '[BOLD] TR→EN  [BOLD] 2016', '[BOLD] TR→EN  [BOLD] 2017', '[BOLD] EN→TR  [BOLD] 2016', '[BOLD] EN→TR  [BOLD] 2017']
All systems are trained using parallel and back-translated data. Adding the copied monolingual data either yields modest improvements or does no damage, so we adopt this strategy for all EN↔TR experiments.
