This is a sentence-transformers model finetuned from sentence-transformers/all-MiniLM-L6-v2. It maps sentences & paragraphs to a 384-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.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("uhyeonjong/fine-tuned-petitions-model")
# Run inference
sentences = [
    '이명박 출금금지 이명박 출극금지 이명박 수사후 구속 탈탈 털어서 엄벌에 처하기 바랍니다.',
    '이명박 출금금지 이명박 출극금지 이명박 수사후 구속 탈탈 털어서 엄벌에 처하기 바랍니다.',
    '장애연금을받기위해전에것을장애6급을다시살릴주길희망합니다 청와대에서 어떻게할는지모르지만 전에는중증장애가되어는데지금효력이없다고관할부서에서 이야기하는데 이것을다시살리수가없나요 나는다시살려서장애연금을받고자하는데 해줄수없나요 ? 부탁합니다',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 1.0000, 0.5313],
#         [1.0000, 1.0000, 0.5313],
#         [0.5313, 0.5313, 1.0000]])
