+# MzansiText — deduplicated release
+
+This is a conservatively deduplicated release of [MzansiText](https://huggingface.co/datasets/uctnlp/mzansi-text), a multilingual pretraining corpus for all eleven official South African languages.
+
+Use the original release to reproduce the paper and its trained models. Use this release for new experiments where cross-source duplicate documents should be removed.
+
+## Dataset details
+
+- Splits: 3,744,654 train rows, 19,940 validation rows, and 19,784 test rows
+- Total: 3,784,378 rows
+- `lang` values: `afr`, `eng`, `nbl`, `nso`, `sot`, `ssw`, `tsn`, `tso`, `ven`, `xho`, `zul`
+- Schema: `text` (string), `lang` (string)
+- All eleven languages occur in every split.
+
+Validation and test sets are capped at approximately 2M tokens per language to prevent high-resource languages from dominating early stopping.
+
+## Deduplication
+
+Deduplication is performed before deterministic splitting. Each document is normalized with Unicode NFC, whitespace is collapsed and trimmed, and exact duplicates are identified by `(lang, SHA-256(normalized text))`. The language is part of the key so identical text labelled as different languages is retained.
+
+The process removed 197,926 duplicate rows:
+
+| Language label | Rows removed |
+|---|---:|
+| `afr` | 165,623 |
+| `zul` | 19,156 |
+| `xho` | 12,910 |
+| `tso` | 231 |
+| `sot` | 3 |
+| `eng` | 1 |
+| `nbl` | 1 |
+| `nso` | 1 |
+| **Total** | **197,926** |
+
+An audit of the combined train, validation, and test splits found no remaining duplicates under this normalization and per-language key.
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("uctnlp/mzansi-text-deduplicated")
+print(dataset)
+```
