Polish Wikipedia user-talk pages (namespace 3) - CC BY-SA 4.0

This slice is rebuilt deterministically from the pinned official Wikimedia dump plwiki-20260901-pages-meta-current (7 sha1-verified shards; https://dumps.wikimedia.org/plwiki/20260901/). Scope is namespace 3 (user talk); mainspace (ns=0) is covered by the existing wikipedia shard and article/project talk (ns=1,5) ships as the separate plwiki_talk slice. This is conversational written Polish - editor-to-editor messages, welcome notices, warnings, disputes, thanks and informal coordination - a register otherwise nearly absent from the corpus.

Per-record page id, title, namespace, last-revision timestamp and canonical URL are preserved; page history is the contributor-attribution trail. Wikitext is stripped with mwparserfromhell; lines occurring in >=1% of documents are removed as cross-document boilerplate; emails, labelled phones, IP literals, labelled national identifiers and 26-digit account candidates are redacted (pattern redaction is not complete anonymization); exact and near deduplication applied within source. The article-talk (ns=1) and project-talk (ns=5) namespaces are excluded by scope decision; they ship as the separate plwiki_talk slice.

What the texts are (user-generated)

These are user-generated texts: messages written by volunteer Wikipedia editors on each other's user-talk pages. Genre: editor-to-editor conversation — help threads, article-source requests, edit discussions and disputes, thanks, adminship debates, and templated bot notices (welcome, warning, account-renaming announcements). Register: informal written Polish — typos, abbreviations, occasional vulgarity and vandalism residue; signed comments (user name + timestamp) are the norm and are kept. Not OCR'd, not machine-translated.

Time span of the content

The content is dated by its own signatures, not only by the dump: 379,443 of 380,527 records contain wiki-signature timestamps spanning 2002-12 to 2026-09 (the bulk falls in 2005-2026; the ~50 pre-2002 date strings found in the scan are quoted historical dates - plwiki launched 2001-09). Per-record created is the dump last-revision date (2002-12-11 - 2026-09-01). Measured by signature/date extraction over all texts (per-year counts in the review thread).

Scrubber and residual-PII spot check

Scrubber that ran: pattern redaction redact_pii() in src/build_plwiki_usertalk_pl.py - e-mail, labelled phone (telefon/tel./ phone), IPv4, parsed IPv6 (incl. compressed notation), labelled PESEL/NIP/REGON, 26-digit account candidates -> [REDACTED:*]. This is not SlayerLab/NERGAL; the shard must be re-run through NERGAL before it is admitted to a release.

Residual-PII spot check (deterministic sample of 60 records, seed 20260928): 0 hits on residual classes not covered above (bare 9-15-digit runs, 26-digit runs, IBAN-like strings, unlabelled IPs, e-mail-like strings incl. obfuscated "at"/"małpa" forms, ul./al./os. street cues, GG/ICQ/Skype handles, PESEL mentions); 3 [REDACTED:*] placeholders remain as evidence of the applied redaction. Manual reading of 8 sampled records found only public wiki attribution (editor user names and timestamps in signatures - the CC BY-SA credit trail) and no private personal data. Residual risk is low but non-zero (60 of 380,527 records, 0.016%; free text can carry data no pattern catches), which is why the NERGAL pass stays a release gate.

Text overlap with the wikipedia / plwiki_talk shards (review audit)

Measured post-build by normalized exact-line and exact-paragraph containment (64-bit blake2b; lines >= 30 chars, paragraphs >= 100 chars; exact-verbatim only):

• vs wikipedia (ns 0): 469 of 4,218,161 user-talk lines match (61,106 chars = 0.006% of user-talk chars); 0 paragraphs. Verbatim article quoting in talk pages is negligible at this unit size.
• vs plwiki_talk (ns 1,5): headline line-char containment is 28.7% (286,157,711 chars), but it concentrates in 47 distinct long notice/template lines that occur on 500+ user-talk pages each - 284,115,864 occurrence chars = 99.3% of the matched chars. These lines are longer than the 160-char line-boilerplate cap, so the build-time rule did not drop them. All other matched lines (4,725 distinct) account for 2,041,847 occurrence chars = 0.2% of user-talk chars; thread copies and genuine quotes (lines on at most 4 pages) are 1,253,089 chars = 0.13%.

Integration gate: at target integration, drop or dedup the shared long notice lines against plwiki_talk; the residual cross-namespace thread duplication (~0.1-0.2%) can ride along with the ordinary cross-source dedup pass. Method and numbers are in the review thread (overlap_check.py, overlap_frequency.py).

Audit trail

The per-record trail ships in this repo: plwiki_user_talk.attribution.jsonl (380,527 lines) and plwiki_user_talk.decisions.jsonl (450,867 lines) are LFS files under .gitattributes (data/*/*.attribution.jsonl, data/*/*.decisions.jsonl), so the PR diff shows pointer text while the Hub resolves the full content at the file view. Both are reproduced byte-for-byte by src/build_plwiki_usertalk_pl.py from the pinned dump; plwiki_user_talk.checksums.json pins their digests.

Limitations: user-talk pages are informal (typos, bot notices, templated warnings, edit disputes, occasional vandalism); comments may quote article text (measured at review: 0.006% of chars match the wikipedia shard verbatim at line level; the larger overlap is shared long notice/template text with plwiki_talk - see the overlap audit section); Record model is a whole talk page; comments are not split.
