On the Difficulty of Translating Free-Order Case-Marking Languages (2021.tacl-1)
Copied to clipboard
| Challenge: | Free-order case-marking languages are more difficult to model than fixed-order languages . however, in medium- and low-resource settings, the overall NMT quality of fixed-or-fixed-order language pairs remains unmatched. |
| Approach: | They investigate whether certain languages are harder to model than others by adding case marking to their models. |
| Outcome: | The proposed models show that word order flexibility in the source language leads to a small loss of NMT quality even though the core verb arguments become impossible to disambiguate in sentences without semantic cues. |
