CleanedWiki-jp CleanedWiki-jp is a cleaned Japanese Wikipedia dataset prepared for LLM pre-training. It is built from Japanese Wikipedia article HTML, converted into Markdown, filtered for trainability. The dataset keeps useful article structure instead of flattening everything into plain text. Suitable body tables are preserved as Markdown tables, and mathematical expressions are preserved in TeX form. Each row also includes a predicted Nippon Decimal Classification (NDC)… See the full description on the dataset page: https://huggingface.co/datasets/KeisukeMiyamoto/CleanedWiki-jp.
