| ItaMix ([https://arxiv.org/abs/2512.18834](https://arxiv.org/abs/2512.18834)) is an Italian pretraining corpus built by combining five publicly available Italian datasets, applying Italian-specific quality filtering, and performing cross-dataset deduplication. |
|
|
| ## Subsets |
|
|
| | Subset | Description | |
| |--------|-------------| |
| | `quality_filtered` | Quality-filtered data before deduplication | |
| | `minhash_deduped` | Document-level MinHash deduplication | |
| | `matched` | Documents appearing in 2+ source datasets | |
|
|
| The matched subset uses cross-dataset agreement as a signal for quality. |
|
|
| ## Usage |
|
|
| ```python |
| from datasets import load_dataset |
| |
| ds = load_dataset("AdaMLLab/ItaMix", "minhash_deduped") |
| ds = load_dataset("AdaMLLab/ItaMix", "quality_filtered") |
| ds = load_dataset("AdaMLLab/ItaMix", "matched") |
| ``` |

|
| ## Pipeline |
|
|
| 1. Quality filtering with Italian-specific thresholds (Latin script ratio, repetition patterns, line quality) |
| 2. Document-level MinHash deduplication (5-gram shingles, 14 bands, 8 hashes per band, similarity threshold 0.8) |
| 3. Cross-source matching to identify documents appearing in 2+ independent sources |
