SentenceTransformer based on klue/roberta-base

This is a sentence-transformers model finetuned from klue/roberta-base. 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("sentence_transformers_model_id")
# Run inference
sentences = [
    '메일 주소를 기입시 별표는 사용할 수 없습니다.',
    '제게 연락을 주실 땐 다음 메일은 사용하지 말아주세요.',
    '급하게 메일을 보내지 말고 발송 전에 차분하게 2번 확인하도록 해',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.1800, 0.0864],
#         [0.1800, 1.0000, 0.3411],
#         [0.0864, 0.3411, 1.0000]])
