PII Span Benchmark (Hard, Synthetic)

1,200 invented business sentences with every personal detail marked by character span: 960 for training and 240 for testing. It is the harder companion to Synthetic De-identification Pairs. That set is clean and regular. This one adds what simple tools miss.

What makes it hard:

Indirect identifiers. the night-shift supervisor in Alder Falls names no one but points to one person.
Obfuscated emails. dana.whitfield at example dot com, dana.whitfield[at]example[dot]com.
Format variety. Five phone formats and an extension, four date formats, spaced and dashed ID and card numbers.
Name variants. Initials, Last, First, lowercase.
Hard negatives. One row in ten has no personal data but looks like it: order numbers, version numbers, internal IPs, product names that are also people's names. A tool that flags them is over-redacting.

Everything is invented. Emails use example.com, phones use the reserved 555-01xx range, IPs use documentation ranges, and card and ID numbers are invalid by construction.

Fields

Field	Meaning
`id`	`pii-0001` to `pii-1200`
`text`	the sentence
`entities`	list of `{label, text, start, end, direct}`; `start` and `end` index into `text`
`styles`	tags for the hard cases present, such as `obfuscated`, `phone_variant`, `date_variant`, `name_initial`, `name_reversed`, `lowercase`, `id_variant`
`hard_negative`	true when the row has no personal data

Labels: PERSON, EMAIL, PHONE, ADDRESS, DATE, ID_NUMBER, CARD_NUMBER, IP_ADDRESS, URL, ORG, QUASI_IDENTIFIER. direct is true for a span that names or contacts a person on its own, and false for indirect ones (QUASI_IDENTIFIER, ORG, DATE) that identify only in combination.

Load it

from datasets import load_dataset
ds = load_dataset("aitrainingdatabroker/pii-span-benchmark-hard")
print(ds["test"][0]["text"])

Scoring suggestion

Report precision and recall per label, and the false-positive rate on hard_negative rows. Count a span correct on exact character match, and report a relaxed overlap score as well.

Limits

Generated from seven sentence templates, so sentence structure is repetitive. Role and organisation pairings are not always plausible.
English, US-style numbers. Names come from a small list.
Indirect identification is the hardest part of real de-identification and this set only samples it. A tool that does well here still needs testing on your own data, reviewed by a person.
Not legal advice and not a certification.
