nomic-embed-indonesian

nomic-embed-indonesian

This is a sentence-transformers model finetuned from nomic-ai/nomic-embed-text-v1.5 specifically for Indonesian language text embedding tasks. It maps Indonesian 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.

🚀 Quick Start

from sentence_transformers import SentenceTransformer

# Load the model (requires trust_remote_code=True)
model = SentenceTransformer("asmud/nomic-embed-indonesian", trust_remote_code=True)

# Indonesian text examples
texts = [
    "search_query: Apa itu kecerdasan buatan?",
    "search_document: Kecerdasan buatan adalah teknologi yang memungkinkan mesin belajar",
    "classification: Produk ini sangat berkualitas (sentimen: positif)"
]

# Generate embeddings
embeddings = model.encode(texts)
print(f"Embedding shape: {embeddings.shape}")  # (3, 768)

🇮🇩 Specialized for Indonesian Language

This model is optimized for Indonesian text understanding across multiple domains including:

• Technology (Teknologi) - AI, gadgets, digital innovation
• Politics (Politik) - Government, elections, public policy

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

⚠️ Important: This model requires trust_remote_code=True due to custom model architecture.

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("asmud/nomic-embed-indonesian", trust_remote_code=True)
# Run inference with Indonesian text
sentences = [
    'search_query: Apa itu kecerdasan buatan?',
    'search_document: Kecerdasan buatan adalah teknologi yang memungkinkan mesin belajar dari data',
    'classification: Produk ini sangat berkualitas dan sesuai harapan (sentimen: positif)',
    'clustering: makanan tradisional Indonesia seperti rendang dan gudeg',
]
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, 0.7154, 0.7378],
#         [0.7154, 1.0000, 0.6583],
#         [0.7378, 0.6583, 1.0000]])
