Simplify-then-Translate: Automatic Preprocessing for Black-Box Translation
Table 4: Translation Edit Rate (TER) score of translations before and after applying the APP simplification for test language-pairs from the FIGS dataset. ‘original’ and ‘simple’ columns show the TER for translations before and after APP where the last column indicates the percentage decrease in TER.
['language', 'original', 'simple', '%Δ']
We also observe that TER decreases for all languages, which is intuitive to understand because the APP simplification brings the sentences closer to their literal human translation. As can be seen, TER decreases for all languages after simplification with a reduction of 6.9%, 6.9% and 7.2% for target languages Hungarian, Romanian and Bulgarian respectively. The reduction in TER correspondingly translates to a reduction in post-editing effort required by translators using the BBMT system as an assistive tool.
