wikipedia: rebuild from the official plwiki dump, label 3.0/4.0 per page
Browse filesReplaces the SpeakLeash plwiki snapshot with plwiki-20260901-pages-articles
(7 shards, sha1 checked against dumpstatus.json and sha1sums.txt), parsed by
src/fetch_wikipedia.py: namespace 0, no redirects, pages carrying {{NPA}}
({{Copyvio}}, {{Plagiat}}) dropped. Each row is labelled by its page's last
revision: before 2023-06-07 00:00 UTC CC-BY-SA-3.0, on or after CC-BY-SA-4.0
(license_for_revision, tested at the cutoff, across time zones, and on a
missing timestamp). Adds an attribution sidecar, build record, licence
evidence and an 80-page hand-checked copyright sample.
v0.2.5 -> rebuild: 1,171,897 -> 1,468,656 documents, 1,844,707,761 ->
3,140,841,847 characters, 707,194,207 -> 1,226,913,508 tokens.
Labels: CC-BY-SA-3.0 190,837, CC-BY-SA-4.0 1,277,819.

## wikipedia — Polish Wikipedia (rebuild from the official dump)
|
| 1485 |
+
|
| 1486 |
+
**Investigated** — 2026-10-05 (October 2026 rights audit, `artifacts/rights_audit_2026-10/reports/wikis_ugc.md`
|
| 1487 |
+
L44-46, `reports/citations.md` L17, `reports/citations/wikimedia.md` section 5;
|
| 1488 |
+
slayerlabs/polish-dynaword-v2#69).
|
| 1489 |
+
|
| 1490 |
+
**Verdict** — `added`, rebuilt for v0.2.6 from the official Wikimedia dump; the SpeakLeash
|
| 1491 |
+
`plwiki` intermediary is removed. 1,468,656 documents / 3,140,841,847 characters /
|
| 1492 |
+
1,226,913,508 tokens (v0.2.5: 1,171,897 / 1,844,707,761 / 707,194,207). Labels per record by
|
| 1493 |
+
the page's last revision: `CC-BY-SA-3.0` 190,837 documents (6.6% of tokens), `CC-BY-SA-4.0`
|
| 1494 |
+
1,277,819 (93.4%); v0.2.5 labelled every row 3.0. Row ids are now `wikipedia_<page id>`
|
| 1495 |
+
("Bitwa pod Grunwaldem": `wikipedia_25295` in v0.2.5, `wikipedia_716` now).
|
| 1496 |
+
|
| 1497 |
+
**Enumeration** — `plwiki-20260901-pages-articles`, 7 shards, each sha1 matched to the
|
| 1498 |
+
dump's `dumpstatus.json` and `sha1sums.txt`, parsed by `src/fetch_wikipedia.py`: 2,877,278
|
| 1499 |
+
pages → 2,304,425 in namespace 0 → 598,071 redirects and 35 pages with `{{NPA}}`
|
| 1500 |
+
(`{{Copyvio}}`, `{{Plagiat}}`) skipped → 1,706,319 converted → 382 exact duplicates →
|
| 1501 |
+
231,717 under 200 characters and 5,564 non-Polish dropped by `build_dynaword.py` →
|
| 1502 |
+
1,468,656. One sidecar line per row (`wikipedia.attribution.jsonl`: page id, revid, title,
|
| 1503 |
+
URL, last-revision time, licence).
|
| 1504 |
+
|
| 1505 |
+
**License evidence** — verified, read 2026-10-05: Terms of Use oldid 554823 (CC BY-SA 4.0
|
| 1506 |
+
and GFDL, in effect June 7, 2023; sha256 `c96ef93b…`), oldid 98524 (CC BY-SA 3.0, June 16,
|
| 1507 |
+
2014), the 3.0 and 4.0 legal code, pl.wikipedia `rightsinfo` (BY-SA 4.0). Inferred: a page
|
| 1508 |
+
edited after the switch may carry its earlier 3.0 text under 4.0 (3.0 §4(b)(ii)). The
|
| 1509 |
+
cutoff is 2023-06-07 00:00 UTC, not the audit's "06-08 if time of day unknown": 06-08 would
|
| 1510 |
+
put that day's 4.0 edits under 3.0, which 4.0 §3(b)(1) does not allow; midnight may put
|
| 1511 |
+
3.0 text under 4.0 for some of the 184 pages last edited that day. The footer switch date
|
| 1512 |
+
was not checked. Evidence in `data/wikipedia/wikipedia.license-evidence.json`.
|
| 1513 |
+
|
| 1514 |
+
**Copyright pastes** — the 31 notice pages unchanged since the dump were re-read: all carry
|
| 1515 |
+
the notice; 4 edited since were not re-read. Web sample of 40 released pages per label
|
| 1516 |
+
(seed 20261006, Earwig's Copyvio Detector, every hit from confidence 0.10 read by hand):
|
| 1517 |
+
1 of 40 per label copied or closely paraphrased from a copyrighted source
|
| 1518 |
+
(`wikipedia_833396` "Obnażyć prawdę", Filmweb's official description; `wikipedia_1126780`
|
| 1519 |
+
"Czarnka", the Drawieński Park Narodowy lake text archived 2012), 6 later copies of
|
| 1520 |
+
Wikipedia, 2 shared titles or stock phrases, 70 below the threshold. 95% Wilson upper
|
| 1521 |
+
bound 12.9% per label. Both pages are kept in this release; dropping them is an open
|
| 1522 |
+
decision. Per page in `data/wikipedia/wikipedia.copyvio-sample.jsonl`.
|
| 1523 |
+
|
| 1524 |
+
**Dedup checks** — reported, not fixed. Exact-text overlap (SHA-256 of raw text) with NKJP1M
|
| 1525 |
+
(main and v0.2.5) and HPLT v0.2.5 is 0 documents (v0.2.5: NKJP1M–Wikipedia 1, HPLT–Wikipedia
|
| 1526 |
+
6). Near duplicates not measured. The `overlap_audit.json` files of `plwiki_talk` and others
|
| 1527 |
+
compare literal ids against the old `data/wikipedia` (revision `fe44303`, 1,171,897 rows) and
|
| 1528 |
+
are stale after the id change.
|
| 1529 |
+
|
| 1530 |
+
**Blockers** — none to merge. Open: the two pasted pages; the time of day of the 4.0 switch;
|
| 1531 |
+
GFDL-era text; `{{ek}}` pages kept; appendix headings left in 56.4% of documents (2.96% of
|
| 1532 |
+
characters from the first such heading on) and whitespace-only lines in 11.9%; NERGAL pass
|
| 1533 |
+
before release.
|
| 1534 |
+
|
| 1535 |
+
**Lesson** — (1) Earwig rated a close paraphrase "none" (0.30): hand-check below its
|
| 1536 |
+
"possible" threshold. (2) Earwig's best hit is usually a later copy of Wikipedia; the real
|
| 1537 |
+
source came from the article's own citation and history ("Czarnka": a 2025 forum hit, the
|
| 1538 |
+
park's 2012 text behind it). (3) The Terms of Use give the day of the licence switch, not
|
| 1539 |
+
the time, so a last-revision label is inexact for one day of edits.

## Licensing — traceable basis
|
| 14 |
+
Wikipedia contributors license their text under CC BY-SA 4.0 under the Wikimedia
|
| 15 |
+
[Terms of Use](https://foundation.wikimedia.org/w/index.php?title=Policy:Terms_of_Use&oldid=554823) in effect since 7 June 2023, and under CC BY-SA 3.0 under the
|
| 16 |
+
[2014-2023 Terms of Use](https://foundation.wikimedia.org/w/index.php?title=Policy:Terms_of_Use&oldid=98524) (both read 2026-10-05 UTC). The pl.wikipedia site licence
|
| 17 |
+
(`rightsinfo`) links BY-SA 4.0. Each row is labelled by its page's last revision in the
|
| 18 |
+
dump:
|
| 19 |
+
|
| 20 |
+
| last revision (UTC) | `license` | documents | tokens | share of tokens |
|
| 21 |
+
|---|---|---:|---:|---:|
|
| 22 |
+
| before 2023-06-07 | `CC-BY-SA-3.0` | 190,837 | 81,023,303 | 6.6% |
|

+
| 2023-06-07 or later | `CC-BY-SA-4.0` | 1,277,819 | 1,145,890,205 | 93.4% |
|
| 24 |
+
|
| 25 |
+
A page last edited on or after the cutoff can still hold 3.0 text from earlier edits;
|
| 26 |
+
[CC BY-SA 3.0](https://creativecommons.org/licenses/by-sa/3.0/legalcode) §4(b)(ii) lets such an adaptation be licensed under "a later
|
| 27 |
+
version of this License with the same License Elements", so it is labelled 4.0. The Terms
|
| 28 |
+
of Use give the day of the switch, not the time. The cutoff is midnight UTC, so the
|
| 29 |
+
184 pages last edited on 2023-06-07 itself are labelled 4.0. If the switch came later
|
| 30 |
+
that day, those last edited before it are 3.0 text under a 4.0 label; a 2023-06-08 cutoff
|
| 31 |
+
(the rights audit's suggestion) would instead put that day's 4.0 edits under a 3.0 label,
|
| 32 |
+
which [4.0](https://creativecommons.org/licenses/by-sa/4.0/legalcode) §3(b)(1) ("this version or later") does not allow. Neither choice is
|
| 33 |
+
exact without the time of the switch. The rule is `license_for_revision` in `src/fetch_wikipedia.py`,
|
| 34 |
+
tested at the cutoff second, across time zones, and on a missing timestamp, which stops the
|
| 35 |
+
build. v0.2.0-v0.2.5 labelled every row `CC-BY-SA-3.0`.
|
| 36 |
+
|
| 37 |
+
Text pasted into an article from a copyrighted source is under neither licence. The
|
| 38 |
+
fetcher drops the 35 pages that carry plwiki's copyright-violation
|
| 39 |
+
notice `{{NPA}}` (or its redirects `{{Copyvio}}`, `{{Plagiat}}`) in the dump.
|
| 40 |
+
On 2026-10-05 the 31 of them not edited since the dump were re-read on
|
| 41 |
+
pl.wikipedia: all carry the notice (some mark one section only; the whole page is dropped).
|
| 42 |
+
The 4 edited after the dump were not re-read. A paste without the notice cannot
|
| 43 |
+
be detected by the build.
|
| 44 |
+
|
| 45 |
+
To measure undetected pastes, 40 released pages per label (seed
|
| 46 |
+
20261006, page-id order) were run through Earwig's Copyvio Detector (web search and
|
| 47 |
+
the page's external links) on 2026-10-05. Every page whose best match reached
|
| 48 |
+
confidence 0.10 or a "possible"/"suspected" verdict was compared by hand
|
| 49 |
+
with the page history and the date of the matching text (see `wikipedia.copyvio-sample.jsonl`):
|
| 50 |
+
|
| 51 |
+
| result | `CC-BY-SA-3.0` | `CC-BY-SA-4.0` |
|

|
| 57 |

|
| 58 |

1 of 40 (`CC-BY-SA-3.0`) and 1 of 40 (`CC-BY-SA-4.0`) pages contain text
|
| 59 |
+
copied or closely paraphrased from a copyrighted source: `wikipedia_833396` "Obnażyć prawdę" (`CC-BY-SA-3.0`); `wikipedia_1126780` "Czarnka" (`CC-BY-SA-4.0`). They stay in
|
| 60 |
+
this release (the sample file notes why each is classed so). The share of such pages is below 12.9% (`CC-BY-SA-3.0`) and
|
| 61 |
+
12.9% (`CC-BY-SA-4.0`), 95% Wilson upper bounds; the labels hold
|
| 62 |
+
6.6% and 93.4% of the tokens. The bounds cover only
|
| 63 |
+
what the detector can find: print sources, translations and paraphrase scoring below the
|
| 64 |
+
hand-check threshold cannot match.

Evidence: `wikipedia.license-evidence.json`.
|

|

## Attribution
|
| 69 |
+
Each row's `author` is `Wikipedia contributors, <page URL>`, e.g.
|
| 70 |
+
`Wikipedia contributors, https://pl.wikipedia.org/wiki/Warszawa`. The page history names the contributors; the Terms of Use
|
| 71 |
+
(section 7) accept a link or URL to the page as attribution.
|
| 72 |
+
`wikipedia.attribution.jsonl` has one line per row: `id`, `pageid`, `revid` (the revision
|
| 73 |
+
in the dump), `title`, `url`, `last_revision_at`, `license`. The row `id` is
|
| 74 |
+
`wikipedia_<page id>` and `created` is the date of `last_revision_at`.
|
| 75 |
+
|
| 76 |
+
The text is modified: wiki markup is converted to plain text (see Provenance).
|
| 77 |
|
| 78 |
## Provenance
|
| 79 |
+
Parsed from the official Wikimedia dump `plwiki-20260901-pages-articles` by
|
| 80 |
+
`src/fetch_wikipedia.py`: 7 shards, whose names, sizes and sha1 are in
|
| 81 |
+
`wikipedia.build.json`, each matched against the dump's `dumpstatus.json` and
|
| 82 |
+
`sha1sums.txt`. v0.2.0-v0.2.5 used the SpeakLeash `plwiki` snapshot
|
| 83 |
+
(`speakleash-ds-pub`); that intermediary was removed in this rebuild.
|
| 84 |
+
|
| 85 |
+
Articles (namespace 0) only. Redirects, empty pages and pages with a copyright-violation
|
| 86 |
+
notice are skipped. Wikitext is converted with mwparserfromhell
|
| 87 |
+
`strip_code(normalize=True, collapse=True)`, as in the sibling Wikimedia builders, after
|
| 88 |
+
removing `<ref>` bodies, file and category links and behaviour switches (`__NOTOC__`).
|
| 89 |
+
Templates (infoboxes, navigation boxes), `<math>`, galleries and comments are dropped;
|
| 90 |
+
table cells stay as flattened text; section headings stay as their own line. Of two
|
| 91 |
+
pages with the same text (sha1 of the stripped text), the lower page id is kept.
|
| 92 |
+
|
| 93 |
+
2,877,278 pages scanned → 2,304,425 in namespace 0 → 598,071 redirects,
|
| 94 |
+
0 empty pages and 35 with a copyright-violation notice skipped
|
| 95 |
+
(0 parser failures) → 1,706,319 converted →
|
| 96 |
+
382 exact duplicates dropped → 1,705,937 read by the build →
|
| 97 |
+
1,468,656 released.
|
| 98 |
+
|
| 99 |
+
Not cleaned: appendix headings ("Zobacz też", "Uwagi", "Przypisy", "Bibliografia", "Linki
|
| 100 |
+
zewnętrzne") stay in 828,389 documents (56.405%), with what is left of those sections
|
| 101 |
+
after the conversion (2.96% of all characters from the first such heading to the end);
|
| 102 |
+
174,668 documents (11.893%) have whitespace-only lines.

|
| 136 |
+
lawyer's opinion), and the time of day of the switch (184 pages last edited on 2023-06-07)
|
| 137 |
+
- text imported from elsewhere under another licence or with extra attribution
|
| 138 |
+
requirements (Terms of Use, Re-use); notices kept in templates are removed by the conversion
|
| 139 |
+
- text first contributed under GFDL before the 2009 move to CC BY-SA, and GFDL dual
|
| 140 |

licensing; only the CC BY-SA grant is relied on
|
| 141 |
+
- quotations inside articles (Art. 29 of the Polish copyright act)
