akhooli / sbert_ar_nli_500k

BERT base trained on 500k Arabic NLI triplets

This is a sentence-transformers model finetuned from aubmindlab/bert-base-arabertv02 . 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 = [
    'هل يغطي العلاج الطبي (أ) أو (ب) تكلفة المعينات السمعية',
    'يغطي الجزء ب من برنامج Medicare (التأمين الطبي) فحوصات السمع والتوازن التشخيصية إذا طلب طبيبك أو مقدم رعاية صحية آخر هذه الاختبارات لمعرفة ما إذا كنت بحاجة إلى علاج طبي. لا يغطي برنامج Medicare فحوصات السمع الروتينية أو المعينات السمعية أو اختبارات تركيب المعينات السمعية.',
    'يتم تعريف الإعاقة غير المرئية ، أو الإعاقة الخفية ، على أنها إعاقات لا تظهر على الفور. قد لا يكون من الواضح أن بعض الأشخاص الذين يعانون من إعاقات بصرية أو سمعية لا يرتدون نظارات أو أجهزة سمعية أو أجهزة سمعية سرية. قد يرتدي بعض الأشخاص الذين يعانون من فقدان البصر العدسات اللاصقة.',
]
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]
