SentenceTransformer based on answerdotai/ModernBERT-base
This is a sentence-transformers model finetuned from answerdotai/ModernBERT-base on the korean_nli_dataset dataset. 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
model = SentenceTransformer("x2bee/sts_nli_tune_test")
sentences = [
'버스가 바쁜 길을 따라 운전한다.',
'녹색 버스가 도로를 따라 내려간다.',
'그 여자는 데이트하러 가는 중이다.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
