This contains data and software for the following paper: Hill, Benjamin Mako and Shaw, Aaron. (2014) "Consider the Redirect: A Missing Dimension of Wikipedia Research." In <em>Proceedings of the 10th International Symposium on Open Collaboration (OpenSym 2014)</em>. ACM Press. doi: 10.1145/2641580.2641616 This is an archival version of the data and software released with the paper. All of these data were originally (and, at the time of writing, continue to be) hosted at: https://communitydata.cc/wiki-redirects/ In wikis, redirects are special pages in that silently take readers from the page they are visiting to another page in the wiki. In the English Wikipedia, redirects make up more than half of all article pages. Different Wikipedia data sources handle redirects differently. For example, the MediaWiki API will automatically "follow" redirects but the XML database dumps treat redirects like normal articles. In both cases, redirects are often invisible to researchers. Because redirects constitute a majority of all pages and see a large portion of all traffic, Wikipedia researchers need to take redirects into account or their findings may be incomplete or incorrect. For example, the histogram on this page shows the distribution of edits across pages in Wikipedia for every page, and for non-redirects only. Because redirects are almost never edited, the distributions are very different. Similarly, because redirects are viewed but almost never edited, any study of views over articles should also take redirects into account. Because redirects can change over time, the snapshots of redirects stored by Wikimedia and published by Wikimedia Foundation are incomplete. Taking redirects into account fully involves looking at the content of every single revision of every article to determine both when and where pages redirect. Much more detail can be found in Consider the Redirect: A Missing Dimension of Wikipedia Research — a short paper that we have written to accompany this dataset and these tools. If you use this software or these data, we would appreciate if you cite the paper. This dataset was previously hosted at this now obsolete URL: http://networkcollectiv.es/wiki-redirects/
