10 Example of a redirect displayed in the `Seattle, Washington page on
11 English Wikipedia`__ which is a redirect to `Seattle`__. Note the
12 small redirect notice below the title.

17 In wikis, **redirects** are special pages in that silently take
18 readers from the page they are visiting to another page in the
19 wiki. In the `English Wikipedia`__, redirects make up more than half
22 Different Wikipedia data sources handle redirects differently. For
23 example, `the MediaWiki API`__ will automatically "follow" redirects
24 but the `XML database dumps`__ treat redirects like normal
25 articles. In both cases, redirects are often invisible to researchers.

30 Because redirects constitute a majority of all pages and see a large
31 portion of all traffic, Wikipedia researchers need to take redirects
32 into account or their findings may be incomplete or incorrect. For
33 example, the histogram on this page shows the distribution of edits
34 across pages in Wikipedia for every page, and for non-redirects only.
35 Because redirects are almost never edited, the distributions are
36 very different. Similarly, because redirects are viewed but almost
37 never edited, any study of views over articles should also take
38 redirects into account.

44 Histograms of pages in the article namespace based on the number of
45 edits on a log scale. The red histogram includes all pages in the
46 article namespace (N = 9,729,989). The blue graphs includes only
47 pages that were not redirects at the point of data collection (N =
50 Because redirects can change over time, the snapshots of redirects
51 stored by Wikimedia and published by Wikimedia Foundation are
52 incomplete. Taking redirects into account fully involves looking at the
53 content of every single revision of every article to determine both
54 when and where pages redirect.

57 Dimension of Wikipedia Research`__ — a short paper that we have written
58 to accompany this dataset and these tools. If you use this software or

68 Generating Redirect Spells
69 =============================
71 Generating redirect spells from an MediaWiki XML dump involves two steps:
73 1. Searching the full text of every revision of every page in a dump to
74 determine if any given revision is a redirect.
76 2. Using the results of (1) to generate a list of "spells" that describe
77 periods of time that articles in a wiki redirect to other articles.
79 We have `publicly released software in Python and R to do these two
80 steps`__ under the `GNU GPL version 3`__. The software is designed for
81 people already comfortable with working with MediaWiki XML dumps and the
82 tools and software necessary to do this.

97 =========================
99 In `our paper`__, we present an analysis of redirect data from English
100 Wikipedia in the dump created in October
101 2012. You can download `the dump files we used`__ from `the Wikimedia
102 Foundation dataset archive`__. Because generating these dumps can be
103 computationally intense, we have published the output of the software
104 above run on the this dump. This includes 9,277,563 redirect spells that
105 our software identified and is the dataset used in the paper.
107 You can download the dataset in the following formats:
109 - `RData (240MB)`__ — Suitable for use in `GNU R`__
110 - `bzip2 compressed tab separated values (178MB)`__ — Suitable for use
111 in other languages and statistical packages.

123 Taking redirects into account is one important step that Wikipedia
124 researchers should take but it is hardly a panacea. As just one example,
125 in conversations after the publication of this paper, we have realized
126 that page moves may lead to additional challenges in interpreting view
127 data and in some cases to challenges in interpreting redirect data
128 itself. This work reflects a step toward increased validity but it is
131 Depending on the research question, a complete picture may need to take
132 redirects, moves, other administrative actions, changing ways of
133 measuring views, bot and bot-assisted editing, along with other
134 currently unidentified features, into account. We hope to extend our
135 work with redirects and explore these issues and we hope other
136 researchers will join us in these efforts to build a better
137 understanding, tools, and datasets that can improve Wikipedia research.

144 how it can be used to come to better findings in Wikipedia research,
