Data Sampling and (In)stability in Machine Translation Evaluation (2023.findings-acl)
Copied to clipboard
| Challenge: | a recent data sampling method skews the annotated data toward shorter documents, not necessarily representative of the full test set. |
| Approach: | They examine different approaches to human evaluation and ranking of machine translation systems at the conference on machine translation . they propose a method that uses available labour budget to sample data in a more representative manner . |
| Outcome: | The proposed method improves representation of document lengths and produces stable rankings of translation quality. |

| Challenge: | Inuktitut language is a member of the Inuit-Yupik-Unangan family . it is spoken in two territories, Nunavut and the Northwest Territories . |
| Approach: | They describe a sentence-aligned Inuktitut–English corpus released in Nunavut . it is the largest parallel corpus of a polysynthetic language released to date . they also describe preliminary experiments on machine translation between the languages . |
| Outcome: | The proposed corpus is the largest sentence-aligned corpus of a polysynthetic language or an Indigenous language of the Americas . the alignments were evaluated and the results were compared with other methods . |
