Gets the Wikidata Q identifier of one or more Wikipedia pages

Usage

tw_get_wikipedia_page_qid(
  url = NULL,
  title = NULL,
  language = tidywikidatar::tw_get_language(),
  cache = NULL,
  overwrite_cache = FALSE,
  cache_connection = NULL,
  disconnect_db = TRUE,
  wait = 1,
  attempts = 10
)

Arguments

url: A character vector with the full URL to one or more Wikipedia pages. If given, title and language can be left empty.
title: Title of a Wikipedia page or final parts of its url. If given, url can be left empty, but language must be provided.
language: Defaults to language set with tw_set_language(); if not set, "en". Use "all_available" to keep all languages. For available language values, see the dedicated Wikimedia page.
cache: Defaults to NULL. If given, it should be given either TRUE or FALSE. Typically set with tw_enable_cache() or tw_disable_cache().
overwrite_cache: Logical, defaults to FALSE. If TRUE, it overwrites the table in the local sqlite database. Useful if the original Wikidata object has been updated.
cache_connection: Defaults to NULL. If NULL, and caching is enabled, tidywikidatar will use a local sqlite database. A custom connection to other databases can be given (see vignette caching for details).
disconnect_db: Defaults to TRUE. If FALSE, leaves the connection to cache open.
wait: In seconds, defaults to 0. Time to wait between queries to Wikidata. If data are cached locally, wait time is not applied. If you are running many queries systematically you may want to add some waiting time between queries.
attempts: Defaults to 10. Number of times it re-attempts to reach the API before failing.

Value

A a data frame with six columns, including qid with Wikidata identifiers, and a logical disambiguation to flag when disambiguation pages are returned.

Examples

if (interactive()) {
  tw_get_wikipedia_page_qid(title = "Margaret Mead", language = "en")

  # check when Wikipedia returns disambiguation page
  tw_get_wikipedia_page_qid(title = c("Rome", "London", "New York", "Vienna"))
}
