NagaYu/sumi-ja-pii-corpus

STATUS: maintained Sumi — synthetic Japanese PII corpus This dataset contains no real personal information. Every name, address, phone number, email address, date of birth, bank account, member ID and My-Number-shaped digit string is generated with a seeded RNG and inserted into the text while recording the offsets, so the gold spans are correct by construction rather than recovered by searching afterwards. No usable card number or My Number exists anywhere in… See the full description on the dataset page: https://huggingface.co/datasets/NagaYu/sumi-ja-pii-corpus.
