cometadata/jina-reranker-v2-multilingual-affiliations-v5

This is a Cross Encoder model finetuned from jinaai/jina-reranker-v2-base-multilingual 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("cometadata/jina-reranker-v2-multilingual-affiliations-v5")
# Get scores for pairs of texts
pairs = [
    ['Université Toulouse', 'a  Université de Toulouse, Mines Albi, CNRS, Centre RAPSODEE ,  Albi ,  France'],
    ['Université Toulouse', 'National Polytechnic Institute of Toulouse'],
    ['School of Fundamental Science and Technology, Keio University 1 , 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522, Japan', 'Center for Supercentenarian Research, Keio University, Tokyo, Japan'],

]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'Université Toulouse',
    [
        'a  Université de Toulouse, Mines Albi, CNRS, Centre RAPSODEE ,  Albi ,  France',
