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 = [
    '주요 대책으로는 출산율 제고를 위한 주거·출산·보육 등 종합적 지원과 고령자 계속고용 활성화 및 고령자 맞춤형 일자리 지원, 노인복지 확대 등 고령화대응 정책노력의 지속이다.',
    '이중 ‘40대 일자리 대책’은 ▲직업훈련·교육 및 생계비 지원 ▲고용 지원 ▲창업 지원 ▲산업·지역 지원 등 40대 맞춤형 지원 방안이 담길 예정이다.',
    '사람이 많이 붐빌때는 조금 불편함은 감안해야 합니다.',
]
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]
