| # Sinhala-script language identification: Sinhala, Pali, Sanskrit |
|
|
| Sentence-level instances of three languages written in Sinhala script, with a |
| leakage-free document-blocked split. Labels: `sin_Sinh`, `pli_Sinh`, `san_Sinh`. |
|
|
| ## Rows |
|
|
| | split | sin_Sinh | pli_Sinh | san_Sinh | total | |
| |---|---:|---:|---:|---:| |
| | train | 83105 | 58309 | 10565 | 151979 | |
| | validation | 10345 | 7317 | 1337 | 18999 | |
| | test | 10567 | 7105 | 1310 | 18982 | |
| |
| ## Construction |
| |
| Built by `scripts/maintainer/resplit_target.py` (config: `target_split` in |
| `config/pipeline.yaml`): |
| |
| 1. Sources pooled and NFC-normalised; text not in Sinhala script removed. |
| 2. Documents: source document ids; for the Pali-Sinhala parallel corpus |
| (sinhala-nlp/pali-sinhala, row-aligned) a sutta starts at each Pali incipit |
| *evam me sutam*, and both sides of a translation pair share the document. |
| 3. Split unit: contiguous block of <= 25 rows within a document. |
| 4. Sentence-level units: split at sentence terminators, packed to <= 200 characters. |
| 5. Exact duplicates removed; texts with conflicting labels removed. |
| 6. Near duplicates removed with MinHash LSH (character 5-grams, Jaccard >= 0.8). |
| 7. Group-stratified {'train': 0.8, 'validation': 0.1, 'test': 0.1} split (seed 42). |
| |
| Leakage check: {'exact_cross_split': 0, 'near_dup_cross_split_j0.8': 0, 'near_dup_cross_split_j0.5': 15005} |
| |
| Length (characters): {'pli_Sinh': {'p50': 138.0, 'p90': 195.0, 'max': 200}, 'san_Sinh': {'p50': 108.0, 'p90': 173.0, 'max': 200}, 'sin_Sinh': {'p50': 155.0, 'p90': 197.0, 'max': 200}} |
