Get all Wikidata Q identifiers of all Wikipedia pages that appear in a given page

Usage

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

Arguments

url: Full URL to a Wikipedia page. 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: Two-letter language code used to define the Wikipedia version to use. Defaults to language set with tw_set_language(); if not set, "en". If url given, this can be left empty.
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 1 due to time-outs with frequent queries. Time to wait between queries to the APIs. 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.
wikipedia_page_qid_df: Defaults to NULL. If given, used to reduce calls to cache. A data frame

Value

A data frame (a tibble) with four columns: wikipedia_title, wikipedia_id, wikidata_id, wikidata_description.
