OverSamu/reranker-biomedbert-base-ncbi-disease-bce-1

ModernBERT-base trained on NCBI Disease

This is a Cross Encoder model finetuned from microsoft/BiomedNLP-BiomedBERT-base-uncased-abstract 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("cross_encoder_model_id")
# Get scores for pairs of texts
pairs = [
    ['holoprosencephaly, alobar', 'pituitary anomalies with holoprosencephaly-like features'],
    ['pneumonias, idiopathic interstitial', 'idiopathic pulmonary fibrosis, familial'],
    ['disease, refsum', 'disease, refsum'],
    ['cdls3', 'cornelia de lange syndrome, x-linked'],
    ['cancers, oropharynx', 'neoplasm, oropharynx'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'holoprosencephaly, alobar',
    [
        'pituitary anomalies with holoprosencephaly-like features',
        'idiopathic pulmonary fibrosis, familial',
        'disease, refsum',
        'cornelia de lange syndrome, x-linked',
        'neoplasm, oropharynx',
    ]
)
# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
