BERT base (UBC V2) trained on 500k Arabic NLI triplets

This is a sentence-transformers model finetuned from UBC-NLP/ARBERTv2. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'لماذا رائحة الغسيل بعد الغسيل',
    'كيفية التخلص من الرائحة: إذا تم اكتشافها على الفور ، فعادة ما يكون غسل الملابس مرة أخرى هو كل ما يلزم لإزالة الروائح الكريهة. إذا لم ينجح ذلك وما زلت تواجه مشاكل ، جرب إحدى الطرق التالية: اغسل مرة أخرى ولكن هذه المرة أضف كوبًا واحدًا من الخل إلى الحمولة (جنبًا إلى جنب مع منظف الغسيل).',
    'حافظ على ملابسك منتعشة وجافة بالمجفف الكهربائي من سيرز. عندما يدور يوم الغسيل ، يمكنك الاعتماد على الأداء الفعال للمجفف الكهربائي. يحتوي سيرز على مجففات تناسب ديكور أي غرفة غسيل. من الفولاذ المقاوم للصدأ إلى تشطيبات الأونيكس ، يسهل تنسيق هذا الجهاز الأنيق مع الغسالة التي تختارها.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
