| # studia_bas |
| |
| Peer-reviewed Polish articles from *Studia BAS*, the socioeconomic and |
| public-policy journal of the Bureau of Research (Biuro Analiz Sejmowych) at the |
| Chancellery of the Sejm. Each record is one article, extracted from the text |
| layer of the official issue PDF. |
| |
| ## Dataset description |
| |
| - **Original platform:** https://studiabas.sejm.gov.pl/journal.nsf/pubBAS.xsp?view=12&seria=4&lang=PL |
| - **Publisher:** Kancelaria Sejmu, Biuro Analiz Sejmowych |
| - **Domain:** academic, economics, social policy and public policy |
| - **Language:** Polish (`pl`) |
| - **License:** `CC-BY-3.0-PL` — https://creativecommons.org/licenses/by/3.0/pl/ |
| - **Created:** 2021-2025 (per article in the `created` column) |
| - **Added:** 2026-07-19 (the registry date in `src/sources.py`, which |
| `build_dynaword.py` stamps; it equals the global `ADDED` the shard was built |
| with, so the shard is left as the committed pipeline produced it) |
|
|
| ## Statistics |
|
|
| | read | kept | characters | tokens (`cl100k_base` proxy) | issues | |
| |---:|---:|---:|---:|---:| |
| | 115 | 112 | 6,089,085 | 2,256,009 | 17 | |
|
|
| The released Parquet uses the canonical DynaWord schema: |
|
|
| `id, text, source, added, created, token_count, license, author` |
|
|
| Every retained article carries its author list in `author`, read from the PDF |
| title page. Because the canonical schema has no column for it, the per-article |
| DOI, attribution URL and source-PDF hash that CC BY attribution requires live in |
| `studia_bas.attribution.jsonl`, one row per Parquet row, in the same order. |
|
|
| ## Provenance and Licensing |
| - **Origin**: Official journal archive at https://studiabas.sejm.gov.pl/journal.nsf/pubBAS.xsp?view=12&seria=4&lang=PL |
| - **License**: Creative Commons Attribution 3.0 Poland (CC BY 3.0 PL). |
| - **License Evidence**: CC BY 3.0 PL applies from issue 2(66)/2021 onward. Issues 1(1) through 1(65) are "Wszelkie prawa zastrzeżone" and are strictly excluded. This is corroborated by the journal's own statement and by pl.wikipedia.org/wiki/Studia_BAS. Eligible range is issues 66-82 = 17 issues. All 17 source PDFs are present locally and their SHA-256 hashes and byte sizes were independently recomputed and matched 17/17 against `data/studia_bas/studia_bas.license-evidence.json`. |
| - **Genre/Register**: Peer-reviewed socioeconomic and public-policy articles, academic register. |
| - **Coverage**: COMPLETE for the eligible range. Cross-checked against Crossref (journal ISSN 2082-0658, 246 works). Crossref lists 132 DOIs for issues 66-82; the corpus has 115. The 17-record difference is fully explained: every one of those 17 DOIs has type 'journal-issue' (issue-level front matter, no title, no authors, no pages), not 'journal-article'. Zero journal-article records are missing, and zero corpus DOIs are absent from Crossref. |
| - **Coverage Cutoff**: `2(82)/2025`. Crossref holds nothing above DOI 10.31268/StudiaBAS.2025.10; the whole 2025.11-2025.25 and 2026.x ranges return HTTP 404. Newest Crossref deposit is 2026-03-06, i.e. roughly a 9-month deposit lag, so later issues may exist without DOIs yet. |
| |
| ## Collection and Filtering |
| - Articles are extracted from the text layer of the official issue PDFs. They are split by DOI title pages. |
| - **Normalization/Modification**: |
| - Running headers, page numbers, author affiliation/contact blocks, terminal |
| bibliographies, and ORCID values are excluded. |
| - Common PII (emails, national identifiers) is replaced with `[PII]` to retain sentence structure. |
| - PDF line wrapping is normalized without flattening paragraph breaks. |
| - **Drops (Language Gate)**: 115 read -> 112 kept. The three language-gate drops are genuine English-language articles, correctly dropped because they contain insufficient Polish: |
| - DOI 10.31268/StudiaBAS.2021.26 ("The EU Fiscal Risk Matrix") |
| - DOI 10.31268/StudiaBAS.2022.08 ("Cultural and creative sectors in the COVID-19 pandemic crisis") |
| - DOI 10.31268/StudiaBAS.2025.08 ("Integration of electricity markets throughout the European Economic Area") |
| |
| ## Argument for Inclusion |
| This source adds high-quality, professional, and peer-reviewed academic texts in the domain of economics, social policy, and public policy, enriching the corpus with formal legal and socioeconomic Polish terminology. |
| |
| ## Metadata Quality |
| - **Record ids** are derived from the article DOI (`studia_bas_<year>_<ordinal>`) and are stable across rebuilds (`preserve_id`). |
| - **Authors** are read from the PDF title page, not from any metadata service. All 112 released author lists were cross-checked against Crossref: 108 match exactly, and none of the 4 differences is an extraction error. Three are errors in Crossref itself, where the PDF is correct ("Dorora"/"Dorota" Wyszkowska in 10.31268/StudiaBAS.2021.36, "Maciej N."/"Maciej J." Nowak in 10.31268/StudiaBAS.2023.02, and a dropped middle initial in 10.31268/StudiaBAS.2024.02); the fourth, 10.31268/StudiaBAS.2021.23, is a Crossref record that carries no author field at all. Co-authors are delimited by the affiliation markers the journal prints on the title page rather than by line spacing, because the journal sets a wrapped name and a following co-author at the same pitch; `src/test_studia_bas_contract.py` pins both that rule and the case of an author list running past the ordinary title-page band. |
| - **PII audit**: `src/audit_studia_bas.py` finds zero emails, ORCIDs, PESEL, |
| NIP or REGON values across all 115 extracted records. Run |
| `src/report_studia_bas_audit.py --corpus <intermediate.jsonl>` to reproduce |
| it. The report also lists advisory extraction-quality heuristics; those |
| matchers are deliberately broad and fire on ordinary inline references, so |
| they do not fail the audit. |
|
|
| ## PII scrubber and NERGAL gate |
|
|
| Scrubber that ran: `scrub_pii()` in `src/fetch_studia_bas.py` — regex pass over |
| the extracted text (e-mail, ORCID, labelled PESEL/NIP/REGON, labelled phone -> |
| `[PII]`), plus structural exclusion of author-affiliation/contact blocks and |
| ORCID values at extraction time. This is **not** |
| [SlayerLab/NERGAL](https://huggingface.co/SlayerLab/NERGAL); the shard |
| ships in v0.2.6 without a NERGAL pass, which runs before v0.2.7 (quoted |
| case material and third-party names can survive any regex pass). The independent audit above (0 structured |
| residuals over all 115 records) is evidence for the current build, not a |
| substitute for the model-based pass. |
