🚀 Arabic-Retrieval-v1.0

This is a high-performance Arabic information retrieval built using the robust sentence-transformers framework, it delivers state-of-the-art performance and is tailored to the richness and complexity of the Arabic language.

🔑 Key Features

🔥 Outstanding Performance: Matches the accuracy of top-tier multilingual models like e5-multilingual-large. See evaluation
💡 Arabic-Focused: Designed specifically for the nuances and dialects of Arabic, ensuring more accurate and context-aware results.
📉 Lightweight Efficiency: Requires 25%-50% less memory, making it ideal for environments with limited resources or edge deployments.

🌍 Why This Model?

Multilingual models are powerful, but they’re often bulky and not optimized for specific languages. This model bridges that gap, offering Arabic-native capabilities without sacrificing performance or efficiency. Whether you’re working on search engines, chatbots, or large-scale NLP pipelines, this model provides a fast, accurate, and resource-efficient solution.

Model Details

Model Description

Model Type: Sentence Transformer
Maximum Sequence Length: 512 tokens
Output Dimensionality: 768 tokens
Similarity Function: Cosine Similarity

Full Model Architecture

SentenceTransformer(
  (0): Transformer({'max_seq_length': 512, 'do_lower_case': False}) with Transformer model: BertModel 
  (1): Pooling({'word_embedding_dimension': 768, 'pooling_mode_cls_token': False, 'pooling_mode_mean_tokens': True, 'pooling_mode_max_tokens': False, 'pooling_mode_mean_sqrt_len_tokens': False, 'pooling_mode_weightedmean_tokens': False, 'pooling_mode_lasttoken': False, 'include_prompt': True})
)

Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference. It is important to add the prefixes <query>: and <passage>: to your queries and passages while retrieving in the folllowing way:

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("omarelshehy/Arabic-Retrieval-v1.0")

# Query 
query = "<query>: كيف يمكن للذكاء الاصطناعي تحسين طرق التدريس التقليدية؟"

# Passages
passages = [
    "<passage>: طرق التدريس التقليدية تستفيد من الذكاء الاصطناعي عبر تحسين عملية المتابعة وتخصيص التجربة التعليمية. يقوم الذكاء الاصطناعي بتحليل بيانات الطلاب وتقديم توصيات فعالة للمعلمين حول طرق التدريس الأفضل.",
    "<passage>: تطوير التعليم الشخصي يعتمد بشكل كبير على الذكاء الاصطناعي، الذي يقوم بمتابعة تقدم الطلاب بشكل فردي. يقدم الذكاء الاصطناعي حلولاً تعليمية مخصصة لكل طالب بناءً على مستواه وأدائه.",
    "<passage>: الدقة في تقييم الطلاب تتزايد بفضل الذكاء الاصطناعي الذي يقارن النتائج مع معايير متقدمة. بالرغم من التحديات التقليدية، الذكاء الاصطناعي يوفر أدوات تحليل تتيح تقييماً أدق لأداء الطلاب."
]

# Encode query and passages 
embeddings_query = model.encode(queries)
embeddings_passages = model.encode(passages)

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings_query, embeddings_passages)

# Get best matching passage to query
best_match = passages[similarities.argmax().item()]
print(f"Best matching passage is {best_match}")
