vietnamese-sbert-finetuned

SentenceTransformer based on bkai-foundation-models/vietnamese-bi-encoder

This is a sentence-transformers model finetuned from bkai-foundation-models/vietnamese-bi-encoder. It maps sentences & paragraphs to a 768-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("kttt294/vietnamese-sbert-finetuned")
# Run inference
sentences = [
    'Nhân_dịp này , thay_mặt UBND thành_phố , ông Lê_Khắc_Nam trao_tặng Bằng khen của Chủ_tịch UBND thành_phố và thưởng 50 triệu đồng cho ban chuyên_án 718M .',
    'Với thành_tích triệt_phá , bắt_giữ các đối_tượng trong đường_dây mua_bán ma_tuý lên tới 20kg , ban chuyên_án đã được UBND TP.',
    'Bộ_phim " Người phán_xử " đã đạt giải Phim_truyền_hình ấn_tượng trong sự hân_hoan của khán_giả yêu_mến bộ_phim .',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.9967, 0.9962],
#         [0.9967, 1.0000, 0.9957],
#         [0.9962, 0.9957, 1.0000]])
