Dataset: WikiLinkGraphs' Redirects

This dataset contains redirects in Wikipedia, i.e. alias names for Wikipedia articles, extracted by processing Wikimedia’s history dumps for the languages de, en, es, fr, it, nl, pl, ru, sv.

Description

• page_id: an integer, the page identifier used by MediaWiki. This identifier is not necessarily progressive, there may be gaps in the enumeration;
• page_title: a string, the title of the Wikipedia article;
• revision_id: an integer, the identifier of a revision of the article, also called a permanent id, because it can be used to link to that specific revision of a Wikipedia article;
• revision_parent_id: an integer, the identifier of the parent revision. In general, each revision as a unique parent; going back in time before 2002, however, we can see that the oldest articles present non-linear edit histories. This is a consequence of the import process from the software previously used to power Wikipedia, MoinMonWiki, to MediaWiki;
• revision_timestamp: date and time of the edit that generated the revision under consideration;
• revision_minor: a boolean flag, with value 1 if the edit that generated the current revision was marked as minor by the user, 0 otherwise;
• redirect.target: a string, the page to which the redict points;
• redirect.tosection: a string, the anchor text of the wikilink;
