| # Polish Wikipedia talk pages (namespaces 1+5) - 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 namespaces 1
|
| (article talk) and 5 (project talk); mainspace (ns=0) is covered by the existing
|
| `wikipedia` shard and user-talk (ns=3) is excluded by scope decision (not
|
| measured). This is conversational written Polish - editorial disputes,
|
| coordination, questions and answers - a register otherwise nearly absent from
|
| the corpus.
|
|
|
| - Non-redirect talk pages enumerated: 544,591
|
| - Source slice retained after QA/dedup: 43,054
|

|
|
|
| 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 user-talk namespace (ns=3) is excluded by scope decision;
|
| its quality was not measured.
|
|
|
| ## What the texts are (user-generated)
|
|
|
| These are **user-generated** wiki talk pages: discussion between volunteer
|
| editors about article content (ns=1, article talk) and about the project itself
|
| (ns=5, "Dyskusja Wikipedii" - policies, classifications, deletion debates).
|
| Genre: editorial discussion - source requests, wording and naming disputes,
|
| style fixes, merge/delete debates, project-wide consultations. Register:
|
| informal written Polish with typos, wiki jargon ("WP:OR", "SDU"), signed
|
| comments (`user name + timestamp`). Not OCR'd, not machine-translated. Record
|
| model: one whole talk page; comments are not split.
|
|
|
| Time span: per-record `created` is the dump last-revision date (2003-02-13 –
|
| 2026-09-01 across 43,054 records); the talk activity itself spans the whole
|
| life of plwiki (ns split: 41,828 article-talk pages, 1,226 project-talk pages).
|
|
|
| ## Scrubber and residual-PII spot check
|
|
|
| Scrubber that ran: **pattern redaction in `src/build_plwiki_talk_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](https://huggingface.co/SlayerLab/NERGAL); these are
|
| user-generated talk pages, so 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):
|
| 25 `[REDACTED:IP]` placeholders remain as evidence of the applied redaction
|
| (including unregistered editors' signatures); the single long-digit-run hit is
|
| an academic DOI citation (`10.1017/9781108668675.006`) - not PII; all other
|
| residual classes (26-digit runs, IBAN-like, unlabelled IPs, e-mail-like incl.
|
| obfuscated "at"/"malpa" forms, `ul.`/`al.`/`os.` street cues, GG/ICQ/Skype,
|
| PESEL mentions) have 0 hits. Manual reading of 8 sampled records found only
|
| public wiki attribution and editorial discussion - no private personal data.
|
| Residual risk low but non-zero (60 of 43,054 records, 0.14%), which is why the
|
| NERGAL pass stays a release gate.
|
|
|
| ## Inclusion argument
|
|
|
| What this adds that `wikipedia` does not: the editorial process around the
|
| articles - talk pages where editors argue about sources, wording, naming,
|
| merges and deletions. That is conversational, multi-voice, disagreement-laden
|
| Polish; the `wikipedia` shard holds only the finished encyclopedic prose. The
|
| namespace partition is exact: `wikipedia` = ns 0, this slice = ns 1+5,
|
| `plwiki_user_talk` (PR #40) = ns 3 - no page is in two slices, and the text
|
| overlap numbers below quantify what still repeats across them.
|
|
|
| ## Text overlap with the wikipedia / plwiki_user_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): 418 of 567,171 talk lines match (75,163 chars =
|
| **0.053%** of this slice's line chars); 1 paragraph (271 chars). Verbatim
|
| article quoting in talk pages is negligible at this unit size.
|
| - vs `plwiki_user_talk` (ns 3): 5,556 lines match (1,207,378 chars = **0.85%**);
|
| 1,111 paragraphs (547,695 chars = **0.39%**); 1,965 of 43,054 records (4.6%)
|
| contain at least one matched line. The matched lines are almost all
|
| page-unique (4,941 of 5,138 distinct matched lines occur on exactly one talk
|
| page) - genuine thread fragments mirrored between article talk and user talk,
|
| not template duplication.
|
|
|
| Integration gate: cross-shard verbatim dedup at integration would move ~0.9% of
|
| chars; no other treatment needed. Method and numbers are in the review thread
|
| (`overlap_check_pr36.py`, `overlap_pr36.json`).
|
|
|
| Limitations: talk pages are informal (typos, edit disputes, occasional vandalism);
|
| comments may quote article text (measured at review: 0.053% of chars match the
|
| `wikipedia` shard verbatim at line level; 0.85% matches `plwiki_user_talk`, almost
|
| all page-unique thread fragments);
|
| Record model is a whole talk page; comments are not split.
