Neural Machine Translation with Reconstruction
Table 2: Correlation between reconstruction score and translation adequacy (and fluency).
['[EMPTY]', '[BOLD] Adequacy', '[BOLD] Fluency']
In the first experiment, we investigate the validity of our assumption that reconstruction score correlates well with translation adequacy, which is the underlying assumption of the approach. We conduct a subjective evaluation: two human evaluators are asked to evaluate the translations of 200 source sentences randomly sampled from the test sets. Two evaluators produce similar results: reconstruction score is more related to translation adequacy than fluency.
