SentenceTransformer based on indobenchmark/indobert-base-p1

This is a sentence-transformers model finetuned from indobenchmark/indobert-base-p1. 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

# Download from the 🤗 Hub
model = SentenceTransformer("damand2061/negasibert-ct")
# Run inference
sentences = [
    'Dengan demikian, seorang model penutur harus mengolah representasi warna dalam konteks dan menghasilkan ujaran yang dapat membedakan warna sasaran dengan ujaran lainnya.',
    'Pada tahun 1975 VTL dibeli oleh Greyhound Lines, menjadi anak perusahaan.',
    'Pada tanggal 24 April 2009, Forum Terbuka IBIS menyetujui versi 2.0.',
]
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]
