This is a Cross Encoder model finetuned from cross-encoder/stsb-roberta-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.

python

from sentence_transformers import CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("foochun/bge-reranker-ft-v2")
# Get scores for pairs of texts
pairs = [
    ['chitra nadarajah', 'chitra a/p nadarajah'],
    ['nik azlina binti nik din', 'norhayati binti mustafa'],
    ['soh min pek', 'pek soh min'],
    ['nurul hazimah binti januiddi', 'salmah binti alias'],
    ['afiq muiz bin azman shah', 'elyana binti emrizal'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'chitra nadarajah',
    [
        'chitra a/p nadarajah',
        'norhayati binti mustafa',
        'pek soh min',
        'salmah binti alias',
        'elyana binti emrizal',
    ]
)
# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
