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 = [
    'لما تحلل أسباب فشل المشروع ده، هتلاقي إن الشركاء ركزوا على الدعاية والإعلان وصرفوا مبالغ ضخمة، ونسيوا يطوروا جودة المنتج الأساسي اللي بيبيعوه.',
    'أَظْهَرَتْ نَتَائِجُ فَرْزِ العَيِّنَاتِ الإِحْصَائِيَّةِ أَنَّ العَجْزَ فِي المِيزَانِ التِّجَارِيِّ يَعُودُ بِشَكْلٍ مُّبَاشِرٍ إِلَى ارْتِفَاعِ فَاتُورَةِ اسْتِيرَادِ مَوَادِّ الطَّاقَةِ.',
    'يُفَضَّلُ اسْتِخْدَامُ سَمَّاعَاتِ الرَّأْسِ المُحِيطِيَّةِ فِي أَلْعَابِ الشُّوتِر (المُواكَبَةِ لِلْمَعَارِكِ) لِتَحْدِيدِ مَكَانِ خُطُوَاتِ الأَعْدَاءِ بِدِقَّةٍ عَالِيَّةٍ.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.7234, 0.3511],
#         [0.7234, 1.0000, 0.3113],
#         [0.3511, 0.3113, 1.0000]])

  يُنْصَحُ بِإِزَالَةِ المَكْيَاجِ بِاسْتِخْدَامِ تِقْنِيَّةِ 'التَّنْظِيفِ المُزْدَوَجِ'؛ أَيْ بِمُزِيلٍ زَيْتِيٍّ أَوَّلاً لِتَفْكِيكِ الدُّهُونِ، ثُمَّ بِالغَسُولِ المَائِيِّ.	تَمْتَازُ النَّظَّارَاتُ الشَّمْسِيَّةُ ذَاتُ الإِطَارِ الكَبِيرِ (عَيْن القِطَّةِ) بِقُدْرَتِهَا عَلَى إِبْرَازِ جَمَالِ المَلَامِحِ وَتَحْدِيدِ عِظَامِ الوَجْهِ بِأَنَاقَةٍ.
  بلاش تبالغوا في عدد الكوشيات أو المخدات الصغيرة على الكنبة، لو زادت عن حدها هتحسس اللي قاعد إن المكان مكركب وكمان هتضطروا تشيلوها كل شوية.	الأثاث الذكي أو متعدد الاستخدامات هو البطل الحقيقي في الشقق الصغيرة، يعني مثلاً سرير جواه سحارة للتخزين أو كنبة بتتحول سرير وقت اللزوم.
  التجارة الإلكترونية مش بس موقع، ده نظام متكامل بيبدأ من المخازن، مروراً بخدمة العملاء، وصولاً لشركة الشحن اللي بتوصل المنتج لبيت العميل.	تُسَاهِمُ إِعْلَانَاتُ رِيتَارْجِتِينْغ (Retargeting) فِي تَذْكِيرِ العُمَلَاءِ بِالمُنْتَجَاتِ الَّتِي أَبْدَوْا اهْتِمَاماً بِهَا، وَهِيَ اسْتْرَاتِيجِيَّةٌ فَعَّالَةٌ لِاسْتِعَادَةِ الزَّوَّارِ المُتَرَدِّدِينَ.
