# Nonsensopedia - Polish satirical wiki (content namespaces)

Content pages from the pinned wikiteam3 dump of nonsa.pl
(https://archive.org/details/wiki-nonsa.pl-20251009, generated 20251009). Nonsensopedia is the
Polish-language satirical encyclopedia - a community wiki parodying Wikipedia
and its sister projects. Content namespaces included: 0 (articles),
100 (Cytaty - quotes), 102 (NonNews - fake news), 104 (NonZrodla - fake
sources), 106 (Slownik - fake dictionary), 108 (Gra - games), 110 (Forum),
114 (Poradnik - guides). Latest revision per page. This is informal,
humorous creative Polish - satire, jokes, parody reference text.

## Provenance and rights

Nonsensopedia text is licensed [CC BY-SA 3.0](https://creativecommons.org/licenses/by-sa/3.0/); the
archive.org item metadata declares the same licenseurl. Each record keeps
its page id, title, namespace, last-revision timestamp and canonical URL -
the page revision history is the attribution trail. The dump was produced by
the WikiTeam preservation project (wikiteam3). Additional third-party
attribution notices must be preserved and remain a review item.
The `created` field is the last revision date, not page creation.

## Processing and limitations

Wikitext is stripped with mwparserfromhell; lines occurring in at least
1% of documents are removed as
cross-document boilerplate (see `artifacts/boilerplate_lines.json`). Unicode and
whitespace normalization, email/labelled-phone/IP/labelled-national-ID/account-candidate pattern redaction, three-window langid
vote, exact and near deduplication within source. The final text must contain at
least 500 characters after redaction. Rejection counts:

```json
{
  "too_little_text": 14338,
  "low_letter_ratio": 23,
  "non_polish_text": 28,
  "too_little_text_after_redaction": 1
}
```

PII filtering masks parsed IPv6 addresses (including compressed forms), labelled
PESEL/NIP/REGON and 26-digit account candidates as well as the existing patterns.
The account filter is conservative and may mask non-account numbers; unlabelled
identifiers, free-form phone numbers, names and personal disclosures may remain.
This is not complete anonymization.

The register is deliberately non-factual: satirical articles, fake news,
fake dictionary entries, quotes, forum posts and game pages. Pages may parody
or quote real Wikipedia articles and other copyrighted works; quoted passages
are not guaranteed disjoint from other corpus shards. The record model is a
whole content page; individual entries are not split.
