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("dev7halo/Ko-sroberta-base-multitask")
# Run inference
sentences = [
    '한국기후·환경네트워크는 콘텐츠 기획 및 개발과 인센티브 제공 등 앱 운영을 주관하고 한국환경공단, 한국환경산업기술원은 앱 제작물 개발과 운영예산 등을 지원한다.',
    '한국기후환경네트워크는 콘텐츠 기획, 개발, 인센티브 등 앱 운영을 관리하고, 한국환경공단과 한국환경산업기술원은 앱 개발 및 운영 예산을 지원합니다.',
    '그 수치는 2015년 메르스의 30퍼센트 감소에서 두 배 이상 증가했습니다.',
]
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]
