w_OccupationEntities {wikiTools}

Gets Wikidata entities with a certain occupation

Description

Returns the Wikidata entities which have the occupation indicated in Qoc, the Wikidata entity for that occupation. Use chunked requests.

Usage

w_OccupationEntities(
  Qoc,
  nlimit = NULL,
  mode = c("default", "count", "wikipedias")
)

Arguments

Qoc

The Wikidata entity of the occupation. For example, Q2306091 sociologist, Q2526255 Film director, etc.

nlimit

If the number of entities found with that occupation exceeds this number, chunked queries are done. This is the number of entities requested in each chunk. No effects in mode='count'. (default=10000, 5000 if mode='wikipedias')

mode

The results you want to obtain: 'default' returns the Wikidata entities which have the occupation indicated; 'count' search in WDQS to know the number of Wikidata entities with P106 property (occupation) set to Qoc; 'wikipedias' returns the Wikidata entities which have the occupation indicated in Qoc, plus the Wikipedia page titles of them. Note that mode='wikipedias' is similar to first launch w_OccupationEntities and then launch w_Wikipedias, but is more efficient. (default='default')

Value

A vector with the Wikidata entities with that occupation by default; if mode='count' the number of entities with that occupation (integer); if mode='wikipedias' a data-frame with Wikidata entities, the number of Wikipedias in which they have page, the Wikipedia languages, the page titles, and finally, the URL to the pages. Last three columns concatenated with "|". Return all Wikipedias pages, not limited by languages.
