🇹🇷 Turkish Embedding Model (bge-m3 Fine-tuned)

This model is a Turkish fine-tuned version of BAAI/bge-m3, optimized for Turkish semantic similarity, retrieval, and RAG (Retrieval-Augmented Generation) tasks. It maps Turkish sentences and paragraphs into a 1024-dimensional dense vector space.

Model Overview

Evaluation Results

Model was evaluated on a Turkish Semantic Textual Similarity (STS) dataset. Compared to the base multilingual BGE-M3 model, the fine-tuned model shows a notable improvement in Pearson correlation, indicating better alignment between cosine similarity scores and human judgments.

The model demonstrates higher linear correlation on Turkish STS benchmarks, producing more consistent semantic scores for Turkish-language retrieval and ranking tasks.

Quick Example

from sentence_transformers import SentenceTransformer, util

model = SentenceTransformer("nezahatkorkmaz/turkce-embedding-bge-m3")

s1 = "Türkiye'nin başkenti Ankara'dır"
s2 = "Ankara Türkiye'nin başşehridir"

emb1, emb2 = model.encode([s1, s2], normalize_embeddings=True)
score = util.cos_sim(emb1, emb2).item()
print(f"Cosine similarity: {score:.4f}")
# Expected output ≈ 0.75–0.80
