Table 5: Results on FR test, cased and detokenized.
['[BOLD] System', '[BOLD] Norm.', '[BOLD] BLEU↑', '[BOLD] chrF1↑', '[BOLD] TER↓']
The single-language fr NMT system achieves a low BLEU score compared to the SMT system Baseline 1 (23.0 vs. 44.6). This is due to the very small amount of parallel data, which is a setting where SMT typically outperforms NMT as evidenced in Zoph et al. Normalization has a big positive impact on all French systems (e.g. 23.0 vs. 27.4 BLEU for fr).
