Dataset: WikiLinkGraphs' 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).

WikiLinkGraphs. This dataset is part of the WikiLinkGraphs family, a collection of datasets extracted from Wikipedia history dumps. See the other datasets:


  • 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;

What is the total size of the dataset, the number of files and the largest file in the dataset?

For each of the 9 languages you will find 18 gzipped files, one for each snapshot from 2001 to 2018 (included). The total dataset size is 79TB, divided among the languages like this:

  • 11G dewiki/
  • 29G enwiki/
  • 5.9G eswiki/
  • 9.2G frwiki/
  • 5.7G itwiki/
  • 4.1G nlwiki/
  • 4.8G plwiki/
  • 6.8G ruwiki/
  • 3.9G svwiki/

The dataset contains 162 files. The average file size is 0.5GB and the largest file is ~3.8GB (enwiki’s snapshot from 2018-03-01).

How are files organized?

Files are divided in directories, one for each language, each directory contains 18 files, one for each year from 2001 to 2018 (included). Like this:
