foochun/bge-reranker-ft

CrossEncoder based on BAAI/bge-reranker-base

This is a Cross Encoder model finetuned from BAAI/bge-reranker-base 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("foochun/bge-reranker-ft")
# Get scores for pairs of texts
pairs = [
    ['quinn toh heng yi', 'heng yi toh quinn'],
    ['mohd iskandi bin hassan', 'muhd iskandi hassan'],
    ['quinn ng ee siu', 'quinn ee siu ng'],
    ['malini doraisamy', 'malini doraisamy'],
    ['see shan fui', 'shanfui see'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'quinn toh heng yi',
    [
        'heng yi toh quinn',
        'muhd iskandi hassan',
        'quinn ee siu ng',
        'malini doraisamy',
        'shanfui see',
    ]
)
# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
