This is a sentence-transformers model finetuned from keepitreal/vietnamese-sbert. 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.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("Kao1412/Classification_Address_New")
# Run inference
sentences = [
    '2 71 /299 c. số212 phố. trầngõ hưng. đạo. quậngõ hồàngõ kiếm. hải. phòng',
    '164 /123 c. số213 kim. mã. phố. quậngõ thanhuyện xuângõ bắc. ninh',
    '214 /194 a, số20 đường, nguyễn, trãi, quận, cầu, giấy, thái, bình',
]
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]
