# Wiadomosci Statystyczne. The Polish Statistician (GUS) - CC BY-SA 4.0 Polish articles

This slice is derived from the deterministic enumeration of the official journal portal
(https://ws.stat.gov.pl/): all articles published from 2022 onward whose landing page
carries an explicit per-article "udostepniony na licencji CC BY-SA 4.0" statement and a
Polish-language PDF marker.

- Enumerated articles (2022+): 460
- With explicit per-article CC BY-SA 4.0 line: 315
- Source slice retained after QA: 182
- Exact title/DOI overlaps with `biblioteka_nauki` excluded: 13
- Proposed records: 169
- Proposed tokens: 1,506,269 (`cl100k_base` proxy)
- Characters: 4,142,041; author coverage: 96.4%
- License: CC BY-SA 4.0 per record
- Immutable source snapshot: https://huggingface.co/datasets/PiotrSty/wiadomosci-statystyczne-pl-articles/tree/078ecdc38e8227faff1769f3ad7f080f44a44bef

Per-record attribution, landing URLs, DOIs, volume/issue, PDF checksums and the verbatim
per-article license line are preserved; preserved landing-page snapshots let a reviewer
re-check every license statement. The DynaWord proposal excludes all exact
normalized-title or DOI matches found against 42,071 pinned
`biblioteka_nauki` rows. Cross-source text deduplication and benchmark checks remain
integration gates. pypdf-derived text can retain layout artifacts, math-alphanumeric
glyph noise, omitted figures and flattened tables. Per-article licensing does not
establish the status of every quoted third-party passage.

## What the texts are

- **Genre**: peer-reviewed statistics-journal content - research articles
  ("Statystyka w praktyce"), statistics-history articles ("Z dziejow
  statystyki"), conference reports and reviews ("Dyskusje. Recenzje.
  Informacje"), obituaries ("In memoriam"). One record per article.
- **Register**: formal academic written Polish with abstracts (PL/EN), JEL
  classes, tables and reference lists; bilingual section headings. Author
  bylines and affiliations are published credits. Not OCR'd (born-digital
  publisher PDFs), not machine-translated.
- **Time span**: publication dates 2022-2026 (per-record `created`; the
  per-article CC BY-SA 4.0 grant starts 2022-01-01).

## Scrubber and residual-PII spot check

Scrubber that ran: **pattern redaction in `src/build_wiadomosci_statystyczne_pl.py`**
- e-mail -> `[REDACTED:EMAIL]`, labelled phone (`telefon`/`tel.`/`phone`) ->
`[REDACTED:PHONE]`. This is **not**
[SlayerLab/NERGAL](https://huggingface.co/SlayerLab/NERGAL); the shard must be
re-run through NERGAL before it is admitted to a release. Merge with
`release: None` is fine meanwhile.

Residual-PII spot check (deterministic sample of 60 of 169 records, seed
20260928): 96 `[REDACTED:*]` placeholders remain (the applied redaction); the
only residual hits are DOIs in bibliographies and ORCID iDs - public academic
identifiers, not PII; 0 hits on all other classes (26-digit runs, IBAN-like,
unlabelled IPs, e-mail-like incl. obfuscated forms, street cues, PESEL
mentions). Manual reading of 8 records found published credits only.

## Normalization (before/after)

`src/build_wiadomosci_statystyczne_pl.py`: `pypdf` text extraction ->
`strip_running_heads()` (drops the "Wiadomosci Statystyczne. The Polish
Statistician, year, vol., issue, pages" running head and repeated digit-masked
page furniture) -> `normalize()` (NFKC; soft-hyphen/zero-width/control strip;
per-line space collapse and trim; pure-number lines dropped; hyphenation across
line breaks joined; wrapped lowercase lines joined; blank runs capped) -> PII
pattern redaction. Before/after excerpts from a real publisher PDF are in the
review thread. Known residue: hyphenation broken by spaces ("Kato - wicach") and
pypdf glyph-spacing artifacts survive in some records - already listed under
Limitations.
