Simplify-then-Translate: Automatic Preprocessing for Black-Box Translation
Table 3: Translation performance (BLEU) before and after of OSEsAPP and OSRuAPP models on six low resource target language pairs from the Open Subtitles corpus.
['language pair', 'original', 'OSEsAPP', 'OSRuAPP']
It can be noted that the performance improves for Catalan (ca) and Portuguese (pt) which are languages similar to the language used for training the simplification corpus. Additionally for Bulgarian an improvement of 4.1% can be observed. Moreover, the performance of OSEsAPP is better than the performance of OSRuAPP. This can be attributed to the fact that En-Ru is a harder language pair to translate than En-Es and hence the simplification model obtained from En-Ru is of worse quality than En-Es.
