CrossEncoder based on cross-encoder/mmarco-mMiniLMv2-L12-H384-v1

This is a Cross Encoder model finetuned from cross-encoder/mmarco-mMiniLMv2-L12-H384-v1 using the sentence-transformers library. It computes scores for pairs of texts, which can be used for text reranking and semantic search.

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 CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("leafxyz/arabic-ecom-cross-encoder-v4")
# Get scores for pairs of inputs
pairs = [
    ['اطعمة معلبة', 'درب شتورة حمص طحينة بالفلفل الحار - 400 غ'],
    ['عطر بيبي روج', 'زيت للأطفال \u200f- Babirose'],
    ['قرص فنش', 'سياقة كونتيسا - 40 سم'],
    ['فمّا قرفة مطحونة', 'زنجبيل مطحون الخليج - 70 غ'],
    ['كيرود', 'كيرود علبة هندسية لون ازرق - 8 قطع'],
]
scores = model.predict(pairs)
print(scores)
# [ 0.6948 -4.2344 -3.0059 -5.4609 -0.0091]

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'اطعمة معلبة',
    [
        'درب شتورة حمص طحينة بالفلفل الحار - 400 غ',
        'زيت للأطفال \u200f- Babirose',
        'سياقة كونتيسا - 40 سم',
        'زنجبيل مطحون الخليج - 70 غ',
        'كيرود علبة هندسية لون ازرق - 8 قطع',
    ]
)
# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
