Data samples

Real records with all canonical metadata fields. Text is truncated only at […].

Record 1

Wyzwania współczesnej polskiej polityki mieszkaniowej

Streszczenie

The article presents the author's insights into the Polish housing policy in the context of the
country's current housing needs and challenges. Special attention is given to the role of housing
policy and citizens' right to adequate and affordable housing[…]

Wstęp

Problematyka potrzeb mieszkaniowych jest z jednej strony tematem ważnym i bardzo potrzebnym w
teorii i praktyce, z drugiej zaś należy do zagadnień niewdzięcznych do analizy. Wynika to m.in. z
faktu, że pod względem sytuacji mieszkaniowej obywateli Polska plasuje się w niechlubnej czołówce
państw członkowskich Unii Europejskiej[…]

Record 2

Zrównoważone banki? Czynniki ESG w unijnych regulacjach mikroostrożnościowych

Streszczenie

The financial sector is highly affected by the spectre of climate change and other
sustainability-related factors, as recognised by various global and EU policies.[…]

Wstęp

Ryzyko środowiskowe, a w szczególności ryzyko klimatyczne wiąże się z wymiernymi stratami
finansowymi dla przedsiębiorstw gospodarki realnej, a więc również instytucji finansowych.[…]

The English abstract present in each article is retained. It represents roughly 1–2% of a document; the article body is Polish.

Provenance and license

• Origin: official issue PDFs from the Studia BAS archive, published by Kancelaria Sejmu RP / Biuro Analiz Sejmowych.
• Collection: src/fetch_studia_bas.py enumerates eligible issues, downloads the PDFs and splits them into articles at DOI title pages using PyMuPDF layout data. No OCR, scraped HTML or third-party mirror is used.
• Integrity: studia_bas.license-evidence.json records the SHA-256 and byte size of all 17 input PDFs. The row-aligned attribution sidecar records each article's DOI, issue, publisher, attribution URL, license URL and modification flag.
• License: Creative Commons Attribution 3.0 Poland.

The license is stated by the journal on its open-access page, in its author instructions, and inside every retained issue PDF. The journal explicitly permits users to read, download, copy, distribute, index and use the articles as software data under CC BY 3.0 PL.

The cutoff is enforced in code: issues before 2(66)/2021 say Wszelkie prawa zastrzeżone and are excluded. Only issues 66 onward, to which the journal applies CC BY 3.0 PL, are downloaded and built.

Normalization and filtering

Normalization runs in the committed fetcher before the intermediate JSONL is built. It includes NFKC Unicode normalization, typography and whitespace cleanup, PDF line-wrap repair, running-header removal, exclusion of author affiliation/contact blocks, terminal bibliography removal, and PII replacement for email addresses, ORCIDs, phone numbers, PESEL, NIP and REGON values. Paragraph boundaries are preserved. Bibliography removal is structure-aware: it removes terminal reference sections while preserving article body and post-bibliography annexes; seven annexes in the source collection are explicitly covered by regression checks.

Real examples:

soft line wrap:     'skut-\nki' → 'skutki'
compound wrap:      'program-\n-mieszkaniowy' → 'program-mieszkaniowy'
non-breaking space: 'w\xa0dniu 11\xa0marca' → 'w dniu 11 marca'
PII:                'jan.kowalski@sejm.gov.pl' → '[PII]'

The released corpus has no standalone Bibliografia, Bibiliografia or
References paragraph. Contract tests separately pin every one of the seven
documents with substantive post-bibliography annexes.

Build results:

The three rejected records are English-only articles. All 112 retained rows have a non-empty author, uniform CC-BY-3.0-PL licensing, unique IDs and distinct text. The committed audit reports zero email, ORCID, PESEL, NIP or REGON matches across all 115 extracted records.

Why include it

The source adds 2.26M tokens of long-form, expert-written Polish on housing, public finance, labour, energy, demography, healthcare and EU regulation. Its formal academic register, legal/economic terminology and citation-dense argument differ materially from the parliamentary speech and institutional-web sources already present in DynaWord.

This source has zero exact-text overlap with the existing local corpus. All 112
retained texts were compared byte-for-byte with 4,366,651 documents across the
other 20 local Parquets; no match was found. A deeper audit of the released
DynaWord biblioteka_nauki shard also found no match by full-text SHA-1,
normalized attribution title, title n-grams in document text or DOI. The current
Biblioteka Nauki journal catalogue
does host 105 of these articles (issues 66–80), but they are absent from
DynaWord's released biblioteka_nauki.parquet; the remaining seven articles,
from issues 81–82/2025, are not present in that catalogue. Keeping a dedicated
source also preserves exact publisher provenance and the specific
CC-BY-3.0-PL license rather than relying on the portal's generic cc-by
classification.

Known limitations:

• the collection is intentionally skewed toward socioeconomic policy and a legislative audience;
• English abstracts and non-Polish quotations embedded in the article body are retained;
• terminal bibliographies are removed, while citation-like material embedded in the article body is retained;
• extraction depends on the journal's post-2021 PDF layout and may require adjustment if that layout changes.

Implementation

• data/studia_bas/: Parquet, statistics, datasheet, attribution sidecar, license evidence and attribution notice;
• src/fetch_studia_bas.py: download, article splitting and normalization;
• src/audit_studia_bas.py and src/report_studia_bas_audit.py: PII and integrity audit;
• src/test_studia_bas_contract.py, src/test_audit_studia_bas.py: source contracts;
• src/sources.py: source registration;
• src/build_dynaword.py: opt-in preserve_id and preserve_created flags, scoped to sources that request them; existing source behavior is unchanged.

src/test_build_dynaword_flags.py verifies the new flags and the unchanged default behavior. The compressed-input path also closes its input handle correctly.

Verification

• Studia BAS contract tests: 30 passed.
• Studia BAS PII/audit tests: 14 passed.
• Cross-source exact-text dedup: 0 matches against 4,366,651 documents
  in all 20 other local Parquets.
• Full src suite: 73 passed, 1 failed out of 74 collected. The sole
  failure is the unrelated Windows-only
  test_samorzad_gov_pl_contract.py::test_release_replacement_rolls_back_on_failure,
  already reproducible on main.
• git diff --check passes.
• Rebuilding from the intermediate JSONL reproduces the released Parquet row-for-row and the statistics apart from the elapsed-time field.

Release files (README.md, CHANGELOG.md, version/date constants and phrase-frequency artifacts) are intentionally left for the maintainers.
