About the Dataset
Data Splits
- Training Data (

Data Source
Apart from the data from our first generation of CCPC, there are additional data sources used by this dataset:
- LIHKG
- HKCancor
- Cantonse-Mandarin Translations
- and various online public datasets
Written Chinese is translated by Microsoft Bing and DeepSeek V3, then translated to Traditional Chinese. Test Set's reference data are translated by a group of professional human translators.
Topic Classification
Considerations for Using the Data
Social Impact of Dataset
This dataset helps preserve the Cantonese language.
Discussion of Biases
As the data was mostly scraped from LIHKG and Telegram, there may be biases in the contents.
Known Limitations
Most Chinese translations in the training data are machine-translated by Microsoft Bing and DeepSeek V3; the translation may not be 100% accurate.

abstract = {Cantonese, a low-resource language [5] that has been used in Southeastern China for hundreds of years, with over 85 million native speakers worldwide, is poorly supported in the mainstream language model for existing translation platforms such as Baidu, Google and Bing. This paper presents a large parallel corpus of 130 thousand Cantonese and Written Chinese pairs. The data are used to train a translation model using the translation pipeline of the Hugging Face Transformers architecture, a dominant architecture for natural language processing nowadays [18]. The BLEU score and manual assessment evaluate the performance. The translation results achieve a BLEU score of 41.35and chrF++ score of 44.88on the entire validation set. The model also works reasonably well with long sentences of over 20 Chinese characters. It achieves a BLEU score of 48.61and chrF++ score of 39.87on long sentences. Those results are comparable with the existing Baidu Fanyi and Bing Translate. We also establish a Cantonese sentence evaluation metric to classify the quality of the source Cantonese sentence by professional translators. We then compare the BLEU and chrF++ scores with the corresponding evaluation score and found that the better the quality of the source sentence, the higher the BLEU and chrF++ scores. Last, we proved that our corpus enabled the Cantonese translation capability of the Chinese BART pre-trained model.},
