# AraMix |
|
|
|
|
|
AraMix (https://arxiv.org/abs/2512.18834v1) is a deduplicated Arabic pretraining corpus containing 178 billion tokens across 179 million documents (in the minhash subset). Rather than scraping the web again, AraMix combines seven publicly available Arabic datasets, applies Arabic-specific quality filtering, and performs cross-dataset deduplication. |

## Subsets |
|
|
|
|
|
| Subset | Documents | Tokens | Description | |
|
|
|--------|-----------|--------|-------------| |
|
|
| `sentence_deduped` | 167.6M | 158.8B | MinHash + sentence-level deduplication | |
|
|
| `minhash_deduped` | 178.9M | 177.8B | Document-level MinHash deduplication only | |
|
|
| `consensus` | 47.9M | 54.1B | Documents appearing in 2+ source datasets | |
|
|
|
|
|
## Usage |
|
|
|
|
|
```python |
|
|
from datasets import load_dataset |
|
|
|
|
|
ds = load_dataset("AdaMLLab/AraMix", "sentence_deduped") |
|
|
ds = load_dataset("AdaMLLab/AraMix", "minhash_deduped") |
|
|
ds = load_dataset("AdaMLLab/AraMix", "consensus") |
|
|
``` |
|
|

|
## Pipeline |
|
|
|
|
|
1. Quality filtering with Arabic-specific thresholds (terminal punctuation, repetition patterns, script ratio) |
|
|
2. Document-level MinHash deduplication (5-gram shingles, 14 bands, 8 hashes per bucket) |
|
|
3. Sentence-level deduplication (3-sentence spans, minimum 3 occurrences) |
|
