ModernUzBERT: A State-of-the-Art Semantic Representation Model for Uzbek

ModernUzBERT is a high-performance embedding model specifically architected and optimized for the Uzbek language. Leveraging the ModernBERT framework, it has been trained on an extensive Uzbek corpus and fine-tuned on 29,000+ domain-specific pairs to achieve superior accuracy in semantic retrieval and document representation.

📊 Dataset and Corpus Details

The model's linguistic foundation is built upon a massive and diverse Uzbek dataset, ensuring deep semantic understanding.

🛠 Usage

Installation

#pip install -U sentence-transformers

from sentence_transformers import SentenceTransformer

# Load the model
model = SentenceTransformer("Orzumurod/ModernUzBERT")

# Example Uzbek sentences
sentences = [
    "Yuridik shaxsning taʼsis hujjatlarida qanday maʼlumotlar aks ettirilishi kerak?",
    "Taʼsischisi, yuridik shaxsning pochta manzili va ustav fondi miqdori hujjatlarda aks etishi lozim."
]

# Generate embeddings
embeddings = model.encode(sentences)

# Compute similarity
similarity = model.similarity(embeddings[0], embeddings[1])
print(f"Similarity Score: {similarity.item():.2f}")

SentenceTransformer(
  (0): Transformer({'max_seq_length': 512, 'do_lower_case': False, 'architecture': 'ModernBertModel'})
  (1): Pooling({'word_embedding_dimension': 768, 'pooling_mode_mean_tokens': True})
)
