reranker-ModernBERT-base-Chem-hungarian

ModernBERT-base trained on Chemistry

This is a Cross Encoder model finetuned from GaborMadarasz/ModernBERT-base-hungarian 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("GaborMadarasz/reranker-ModernBERT-base-hungarian")
# Get scores for pairs of texts
pairs = [
    ['Milyen halmazállapotú a klór szobahőmérsékleten?', 'Gáz'],
    ['Milyen halmazállapotú a klór szobahőmérsékleten?', 'Gáz.'],
    ['Mi az izoméria fogalma?', 'Azonos összegképletű, de eltérő szerkezetű és tulajdonságú anyagok. '],
    ['Melyik elektronhéjon található a hidrogénatom egyetlen elektronja?', 'Az első héjon.'],
    ['Milyen felhasználási területei vannak a szilíciumnak?', 'Ötvözőelemként, tranzisztorok, integrált áramkörök, fényelemek előállítására.'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'Milyen halmazállapotú a klór szobahőmérsékleten?',
    [
        'Gáz',
        'Gáz.',
        'Azonos összegképletű, de eltérő szerkezetű és tulajdonságú anyagok. ',
        'Az első héjon.',
        'Ötvözőelemként, tranzisztorok, integrált áramkörök, fényelemek előállítására.',
    ]
)
# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
