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("Pranjal2002/all-mpnet-base-v2")
# Get scores for pairs of texts
pairs = [
    ['What consolidation trends among competitors are highlighted in disclosures affecting Regions Financial Corporation’s regional banking operations?', '10-K'],
    ['What consolidation trends among competitors are highlighted in disclosures affecting Regions Financial Corporation’s regional banking operations?', 'Earnings'],
    ['What consolidation trends among competitors are highlighted in disclosures affecting Regions Financial Corporation’s regional banking operations?', 'DEF14A'],
    ['What consolidation trends among competitors are highlighted in disclosures affecting Regions Financial Corporation’s regional banking operations?', '8-K'],
    ['What consolidation trends among competitors are highlighted in disclosures affecting Regions Financial Corporation’s regional banking operations?', '10-Q'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'What consolidation trends among competitors are highlighted in disclosures affecting Regions Financial Corporation’s regional banking operations?',
    [
        '10-K',
        'Earnings',
        'DEF14A',
        '8-K',
        '10-Q',
    ]
)
# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
