Dataset: WikiLinkGraphs' RawWikilinks Snapshots

This dataset contains wikilink snapshots, i.e. links between Wikipedia articles, extracted by processing each revision of each Wikipedia article (namespace 0) from Wikimedia’s history dumps for the languages de, en, es, fr, it, nl, pl, ru, sv. The snapshots were taken on March 1st, for the years between 2001 and 2018 (included).

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;
• user_type: a string ("registered" or "anonymous"), specifying whether the user making the revision was logged-in or not;
• user_username: a string, the username of the user that made the edit that generated the revision under consideration;
• user_id: an integer, the identifier of the user that made 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;
• wikilink.link: a string, the page linked by the wikilink;
• wikilink.anchor: a string, the anchor text of the wikilink;
• wikilink.section_name: the name of the section wherein the wikilink appears;
• wikilink.section_level: the level of the section wherein the wikilink appears;
• wikilink.section_number: the number of the section wherein the wikilink appears;
• wikilink.is_active: a boolean representing whether the page pointed to by the link was existing in that moment or not.
