| - **Note:** Deduplicated against the mined MT dataset |
| |
| ### Mined MT Dataset (`wiki_mined.csv`) |
| - **Source:** Aligned Piedmontese–Italian Wikipedia article pairs via Wikidata interlanguage links |
| - **Alignment:** LaBSE cosine similarity ≥ 0.85; sentences between 5–100 words |
| - **Columns:** `pms` (Piedmontese), `it` (Italian) |
|
|
| ### Translated Pairs (`translations_merged.csv`) |
| - **Source sentences:** Italian from FLORES+ dev set |
| - **Reference:** Human translations from Vico & Libovický (2026) |
| - **MT outputs:** Three NLLB conditions — `NLLB-avg`, `NLLB-avg+MT`, `NLLB-avg+DAE+MT` |
| - **Columns:** `flores_id`, `source`, `reference`, `translations_NLLB-avg`, `translations_NLLB-avg+MT`, `translations_NLLB-avg+DAE+MT` |
