LOUPE — initial dataset

The init split contains all 300 original SynthPAI seed personas and all 7,823 original comments, grouped into one row per author. This is the initial source dataset: no anonymization, model inference, or predictions were performed.

Source and attribution

Adapted from SynthPAI by Yukhymenko et al., A Synthetic Dataset for Personal Attribute Inference. Source repository: eth-sri/SynthPAI, revision ba9edc9c8aa1d398bc43bb619a8d859351df9d9c. Dataset license: CC BY-NC-SA 4.0. Source paths, verified SHA-256 hashes, and author assignments are in manifest.json. The filtered 294-profile evaluation artifact is not used.

Changes: join comments to seed authors, convert the eight reference attributes to strings, render a deterministic eight-line profile, and add split/provenance metadata. Comment text and raw-file order are preserved exactly. Raw source files are cached unchanged by the builder; extra seed fields, usernames, generation instructions, reviewer labels, and historical model outputs are excluded from the normalized table.

Columns

• profile_id: original source author ID; rows follow seed-file order.
• profile: eight original reference values as strings (age, sex, residence, birthplace, education, occupation, relationship status, and income level).
• profile_text: deterministic labeled rendering of those eight values.
• comments: every original comment by this author in source order.
• usage_split: test for all 300 authors in every split; no development subset is reserved. This column is separate from the Hugging Face split names.
• provenance: source revision, profile value character intervals, and aligned comment IDs, one-based source line numbers, thread IDs, and parent IDs.

The structured profile and provenance are reference/evaluator data. Authors share threads, so author assignment does not eliminate thread dependence. This public synthetic corpus does not establish real-person anonymity or absence of model training contamination. Comments can disclose profile values directly.

Anonymizer and reference splits

The init split remains the original reference data. Each transformed split preserves its rows and columns and adds profile_anonymized. Comments remain unchanged. The shared reader schema supplies null for this column in init. No reconstruction predictions are included.

Each split has a manifests/<split>.json describing its model/deployment identity, source revision, policy, settings, runtime versions, and file hashes. Any unknown checkpoint revision or quantization is recorded explicitly rather than inferred from a served alias. provenance/<split>.jsonl contains per-profile raw responses, statuses, and either selected spans or structured anonymized values.

The native detectors and span-selection generative adapters receive profile_text and mask detected spans with [REDACTED]. Native detector coverage differs. An unchanged profile is a valid zero-detection result.

Full profile redaction reference

full_redaction is a reference condition, not an anonymizer competitor. All eight profile values in profile_anonymized are [REDACTED]; the field labels remain. All 300 original profiles and all 7,823 comments are preserved in their original columns, with the same comment text and order. Only the released profile view is redacted. Generation history remains in the manifest and provenance.

This condition measures reconstruction with every profile value suppressed and the original comments still available. It differs from a comments-only condition, which omits the profile text entirely. It does not imply that comments are redacted or that the full dataset contains no personal attributes.

Author assignment update

All 300 authors now have usage_split="test" in init and every anonymizer and reference split. This all-test-v1 metadata update replaces the earlier 50/250 assignment from revision 875ebdc725a809b19a672a2150b6a0904ca3f3a6. Every other data column, including profiles, comments, and anonymized text, is unchanged. Inference was not rerun. Manifests record the update and new Parquet hashes; original generation provenance and its source revisions remain historical records. Earlier pilot use remains part of the experiment history; this reassignment does not establish an untouched holdout.
