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.

python

from sentence_transformers import CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("cometadata/gte-multilingual-reranker-affiliations")
# 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'],
    ['School of Fundamental Science and Technology, Keio University 1 , 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522, Japan', 'g    Toin Human Science and Technology Center, Department of Materials Science and Technology, Toin University of Yokohama, 1614 Kurogane-cho, Aoba-ku, Yokohama 225, 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',
        'National Polytechnic Institute of Toulouse',
