# character-bert_NArabizi

This model is a **CharacterBERT-based model trained from scratch** on the **NArabizi raw data**, code-switched dialectal Arabic (NArabizi) from social media.

It was introduced in the paper:

- [Can Character-based Language Models Improve Downstream Task Performances in Low-Resource and Noisy Language Scenarios?](https://aclanthology.org/2021.wnut-1.7/)  
  (Riabi et al., 2021, W-NUT)

---

## 📝 Description

The model follows the **CharacterBERT** architecture (El Boukkouri et al., 2020), which removes WordPiece tokenization in favor of a **Character-CNN module** that generates full word representations from raw character sequences.
