Wikidata Infernal

Wikidata Infernal is an API that allows you to infer new facts from Wikidata. It uses a set of rules to infer new facts from existing ones. The generated statements will have qualifiers to indicate the source and method of the inference. Output is an array of statements in JSON/Wikidata format.

• /P131/LAT/LON

  Finds items with a P131 near the given location, and returns their administrative region (P131) as statements.

  Example (a point in Cambridge, UK)

• /name_gender/NAME

  Parses a (western-style, "first_name last_name") personal name, and tries to infer items for first and last names, as well as gender, based on first names.

  Example (Yours Truly)

• /country_year/ITEM/YEAR

  /country_year/ITEM/YEAR/PROPERTY

  For a given location item (e.g. a city), finds the country in the given year, and returns it as a statement. Will return the "default" country (no qualifiers) if no better match can be found.

  Example (country of citizenship for people born in Cologne in 1921)

• /cross_categories/CATEGORY_ITEM/LANGUAGE/DEPTH

  For a given Wikidata item that is for a category, finds all pages with the category on the sitelinked wikis (to depth), the items for these pages, and returns the pages for the items matching the language wiki (not using disambigution pages, or pages already in the language wiki category).

  Example (Category:Polish skydivers for en.wikipedia.org, depth 5)

• /referee/ITEM

  For a given Wikidata item, searches linked external IDs, official website, and all web pages linked from associated Wikipedia articles for potential references to statements in the item. It tries to use different date formats, and the respective label for the language of the website.

  Example (Carlo Creazzo, random example)

• /isbn/isbn/ISBN

  For a given ISBN, searches ISBN sources and generates a Wikibase REST API POST payload for a new item.

  Example (Le seigneur des anneaux T1 La fraternité de l'anneau, by JRR Tolkien)

• /isbn/item/ITEM

  For a given Wikidata item with an ISBN statement, searches ISBN sources and generates a Wikibase REST API patch for the item.

  Example (Caballeros de fortuna, by Luis Landero)

• /viaf_search/QUERY

  For a given plain text search query, returns the VIAF search results.

  Example

• /initial_search/QUERY

  For a given human name with initials, find Wikidata items with labels/aliases that match the name with expanded initials.

  Example ( as HTML )

• /change_wiki/SOURCE_WIKI/TARGET_WIKI

  Pass a JSON array with page titles in SOURCE_WIKI as a POST payload. Returns a JSON object with the SOURCE_WIKI titles as keys and the corresponding TARGET_WIKI titles as values.
  Note: Keys will have spaces instead of underscores.

  THIS REQUIRES POST!
