Great news! Beijing Academy of Artificial Intelligence(BAAI) published a new dataset Chinese Corpus Internet (CCI v1.0.0), a large-scale dataset for Chinese language model pretraining and collected with leading institues in China. This open-source dataset is designed to offer an important data foundation for the AI Large-Language Model in Chinese. It includes contents from >1000 most important websites in Chinese, from Jan. 2001 to Nov. 2023. It has been filtered for high quality, content safety, deduplication, and content correction with lots of manual checking. This dataset is 104GB in total, filtered from a much larger one (original size is >800GB). I would encourage you to include this dataset for training an LLM supporting Chinese as one of its languages.

The reason this was necessary is a bit funny: as Google reported in their MADLAD paper, over half of Mandarin CommonCrawl text is porn. Perhaps a robots.txt issue? Great firewall? I have no idea.
