Description

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.

Examples

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