Neural Machine Translation with External Phrase Memory
Table 2: Evaluation of translation quality in 4-gram BLEU score.
['[BOLD] Models', '[BOLD] NIST02', '[BOLD] NIST03', '[BOLD] NIST04', '[BOLD] NIST05', '[BOLD] NIST06', '[BOLD] NIST08', '[BOLD] Ave.']
It is also reasonable to doubt that our models are just generate the target phrases without considering the positions, as this will also (almost surely) increase the 1-gram and 2-gram BLEU scores and hence increase the final BLEU scores.
