# Darija Toxicity Classifier π²π¦
|
| 22 |
+
|
| 23 |
+
A transformer-based NLP model for detecting toxic content in Moroccan Darija and Arabizi.
|
| 24 |
+
|
| 25 |
+
This model is specifically designed to handle the linguistic complexity of Moroccan dialect, including Arabizi (Arabic written in Latin characters with numbers) such as:
|
| 26 |
+
* `3` β ΨΉ
|
| 27 |
+
* `7` β Ψ
|
| 28 |
+
* `9` β Ω
|
| 29 |
+
|
| 30 |
+
It also supports code-switched text mixing Darija, Arabic, French, English, and Tamazight.

| **Architecture** | Fine-tuned from `SI2M-Lab/DarijaBERT-arabizi` |
|
| 40 |
+
| **Task** | Binary Sequence Classification (Safe / Toxic) |
|
| 41 |
+
| **Framework** | Hugging Face Transformers |
|
| 42 |

## π Quick Inference (Transformers)
|
| 47 |
+
|
| 48 |
+
```python
|
| 49 |
+
from transformers import pipeline
|
| 50 |
+
|
| 51 |
+
classifier = pipeline(
|
| 52 |
+
"text-classification",
|
| 53 |
+
model="0khacha/darija-toxicity-classifier"
|
| 54 |
+
)
|
| 55 |
+
|
| 56 |
+
result = classifier("salam khouya")
|
| 57 |
+
print(result)
|
| 58 |
+
# Output: [{'label': 'SAFE', 'score': 0.9845}]

## π§ What Makes This Model Special?
|
| 64 |
+
|
| 65 |
+
### π Dialect-Aware
|
| 66 |
+
Built specifically for Moroccan linguistic patterns β not generic Arabic.
|
| 67 |
+
|
| 68 |
+
### π’ Arabizi Handling
|
| 69 |
+
Understands numeric character substitutions like:
|
| 70 |
+
* `in3al`
|
| 71 |
+
* `sa7a`
|
| 72 |
+
* `3likom`
|
| 73 |
+
|
| 74 |
+
### π§Ή Custom Preprocessing
|
| 75 |
+
The model was trained with specialized normalization:
|
| 76 |
+
* Lowercasing
|
| 77 |
+
* Removing dash/underscore splitting (`w-a-l-o` β `walo`)
|
| 78 |
+
* Fixing spaced characters (`n 3 a l` β `n3al`)
|
| 79 |
+
* Reducing elongation (`heeeey` β `hey`)
|
| 80 |
+
* Whitespace normalization
|
