# Namaa-Reranker-v1 🚀✨

**NAMAA-space** releases **Namaa-Reranker-v1**, a high-performance model fine-tuned on [unicamp-dl/mmarco](https://huggingface.co/datasets/unicamp-dl/mmarco) to elevate Arabic document retrieval and ranking to new heights! 📚🇸🇦

This model is designed to **improve search relevance** of **arabic** documents by accurately ranking documents based on their contextual fit for a given query.

## Key Features 🔑

- **Optimized for Arabic**: Built on the highly performant [Omartificial-Intelligence-Space/Arabic-Triplet-Matryoshka-V2](https://huggingface.co/Omartificial-Intelligence-Space/Arabic-Triplet-Matryoshka-V2) with exclusivly rich Arabic data.
- **Advanced Document Ranking**: Ranks results with precision, perfect for search engines, recommendation systems, and question-answering applications.
- **State-of-the-Art Performance**: Achieves excellent performance compared to famous rerankers(See [Evaluation](https://huggingface.co/NAMAA-Space/Rerankerv1#evaluation)), ensuring reliable relevance and precision.

## Example Use Cases 💼

- **Retrieval Augmented Generation**: Improve search result relevance for Arabic content.
- **Content Recommendation**: Deliver top-tier Arabic content suggestions.
- **Question Answering**: Boost answer retrieval quality in Arabic-focused systems.

## Usage 

# Within sentence-transformers
The usage becomes easier when you have [SentenceTransformers](https://www.sbert.net/) installed. Then, you can use the pre-trained models like this:

```python
from sentence_transformers import CrossEncoder
model = CrossEncoder('NAMAA-Space/Namaa-Reranker-v1', max_length=512)

Query = 'كيف يمكن استخدام التعلم العميق في معالجة الصور الطبية؟'
Paragraph1 = 'التعلم العميق يساعد في تحليل الصور الطبية وتشخيص الأمراض'
Paragraph2 = 'الذكاء الاصطناعي يستخدم في تحسين الإنتاجية في الصناعات'

scores = model.predict([(Query, Paragraph1), (Query, Paragraph2)])
```

## Evaluation

We evaluate our model on two different datasets using the metrics **MAP**, **MRR** and **NDCG@10**: 

The purpose of this evaluation is to highlight the performance of our model with regards to: Relevant/Irrelevant labels and positive/multiple negatives documents:

Dataset 1: [NAMAA-Space/Ar-Reranking-Eval](https://huggingface.co/datasets/NAMAA-Space/Ar-Reranking-Eval)

As seen, The model performs extremly well in comparison to other famous rerankers. 

WIP: More comparisons and evaluation on arabic datasets.
