SentenceTransformer based on dragonkue/multilingual-e5-small-ko-v2

This is a sentence-transformers model finetuned from dragonkue/multilingual-e5-small-ko-v2 on the json dataset. It maps sentences & paragraphs to a 384-dimensional dense vector space and can be used for retrieval.

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
queries = [
    'query: 병과명',
]
documents = [
    'passage: 한글명: 병과명\n영문약어명: BR_NM\n단어조합: 병과 + 명\n단어영문약어조합: BR + NM\n단어도메인분류조합: 명\n마지막단어: 명\n마지막단어도메인분류명: 명\n설명: 군사조직에서 군인이 능력에 따라 수행하는 주요 임무를 분류한 것의 이름',

]
query_embeddings = model.encode_query(queries)
document_embeddings = model.encode_document(documents)
print(query_embeddings.shape, document_embeddings.shape)
# [1, 384] [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(query_embeddings, document_embeddings)
print(similarities)
# tensor([[0.9488, 0.0378, 0.2989]])
