| # CamelParser-Dialects |
| **CamelParser-Dialects** is a neural dependency parsing model for **dialectal Arabic** and Modern Standard Arabic (MSA), designed under the **CATiB dependency formalism**. |
|
|
| It is based on the **biaffine attention parser** architecture introduced by Dozat and Manning (2017), implemented using [SuPar](https://github.com/yzhangcs/parser). |
| The model leverages **CamelBERT-MIX**, a pretrained language model trained on a large and diverse Arabic corpus. |

|
|
| The recommended checkpoint is the **all-variety model (`MSA-EGY-GLF`)**, which provides the best overall cross-dialect performance. |
