| # PangeanicYueEn - Cantonese English Parallel Corpus |
|
|
| **PangeanicYueEn** is a large-scale Cantonese-English parallel corpus designed for machine translation, multilingual large language model (LLM) training, cross-lingual NLP research, retrieval-augmented generation (RAG), bilingual embeddings, instruction tuning, and multilingual AI systems. |
|
|
| This release contains **150,000 Cantonese-English sentence pairs** sampled from a larger corpus of approximately **8.05 million parallel sentence pairs**. For the complete dataset, please contact [Pangeanic](https://pangeanic.com/contact-us) |
|
|
| The dataset focuses specifically on **written Cantonese (Yue Chinese)** paired with English translations, providing valuable training data for one of the most underrepresented Chinese language varieties in modern AI systems. |
|

|
|
| # Why Cantonese Matters for AI |
|
|
| Most multilingual AI systems are heavily trained on: |
|
|
| * English |
| * Mandarin Chinese |
| * Spanish |
| * French |
| * German |
|
|
| However, **Cantonese (Yue Chinese)** remains significantly underrepresented despite being spoken by tens of millions of people worldwide across: |
|
|
| * Hong Kong |
| * Macau |
| * Guangdong |
| * Southeast Asia |
| * North America |
| * Europe |
|
|
| As demand grows for multilingual AI, conversational assistants, translation systems, and regionally adapted LLMs, high-quality Cantonese datasets become increasingly important. |
|
|
| PangeanicYueEn helps address this gap by providing large-scale Cantonese-English parallel text suitable for modern AI development. |
