SentenceTransformer based on x2bee/KoModernBERT-base-mlm_v02

This is a sentence-transformers model finetuned from x2bee/KoModernBERT-base-mlm_v02 on the korean_nli_dataset dataset. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

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 SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("x2bee/KoModernBERT_SBERT_compare_mlmlv5")
# Run inference
sentences = [
    '한 여자와 소년이 경찰 오토바이에 앉아 있다.',
    '여자와 소년이 밖에 있다.',
    '한 남자가 물 위에 밧줄을 매고 있다.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
