    <description descriptionType="Abstract">&lt;p&gt;Wikipedia is an ongoing endeavor to create a free encyclopedia through an open computer-mediated collaborative effort. How does Wikipedia grow and maintain its coverage? This page contains supporing material relevant to a publication that examines this question.&lt;/p&gt;

	&lt;li&gt;Diomidis Spinellis and Panagiotis Louridas. The collaborative organization of knowledge. Communications of the ACM, 51(8):68&amp;ndash;73, August 2008. (&lt;a href=""&gt;doi:10.1145/1378704.1378720&lt;/a&gt;)&lt;/li&gt;

&lt;p&gt;In the above paper, a longitudinal study of Wikipedia&amp;#39;s evolution shows that although Wikipedia&amp;#39;s scope is increasing, its coverage is not deteriorating. This can be explained by the fact that referring to an non-existing entry typically leads to the establishment of an article for it. Wikipedia&amp;#39;s evolution also demonstrates the creation of a large real world scale-free graph through a combination of incremental growth and preferential attachment.&lt;/p&gt;

&lt;p&gt;Though this data set you can download the processed results. The file starts with a header giving various attributes of the processed data set.&lt;/p&gt;

&lt;pre&gt;% Number of bins: 72

&lt;p&gt;Next comes one line of data for each one of Wikipedia&amp;#39;s entries. Here is an example.&lt;/p&gt;

&lt;pre&gt;A (musical note):1128386876:Mailer diablo:1130566991:MrD9:10:7:18:0:0:0:0:0:0:0:

&lt;p&gt;Each line contains the following fields.&lt;/p&gt;

	&lt;li&gt;Entry name&lt;/li&gt;
	&lt;li&gt;Time of first definition (in seconds since Unix epoch)&lt;/li&gt;
	&lt;li&gt;Name of the contributor who first defined the entry&lt;/li&gt;
	&lt;li&gt;Time of first reference (in seconds since Unix epoch)&lt;/li&gt;
	&lt;li&gt;Name of the contributor who first referenced the entry&lt;/li&gt;
	&lt;li&gt;Number of references&lt;/li&gt;
	&lt;li&gt;Number of contributors&lt;/li&gt;
	&lt;li&gt;Number of revisions&lt;/li&gt;
	&lt;li&gt;Number of reverts&lt;/li&gt;
	&lt;li&gt;For each one of the time period bins (72 in this file) the number of references to the entry&lt;/li&gt;
	&lt;li&gt;The letter &amp;quot;E&amp;quot;&lt;/li&gt;

&lt;p&gt;The fields are colon-separated. Colons in the input data are converted to an underscore.&lt;/p&gt;

&lt;p&gt;Finally, come lines summarizing the data set&amp;#39;s characteristics for each time period. Here is an example.&lt;/p&gt;

&lt;pre&gt;2001-07-01 4851 0  27106   15129        13458   531

&lt;p&gt;Each line contains the following fields.&lt;/p&gt;

	&lt;li&gt;Start date of this period&lt;/li&gt;
	&lt;li&gt;Number of entries&lt;/li&gt;
	&lt;li&gt;Number of entries that are stubs&lt;/li&gt;
	&lt;li&gt;Number of references&lt;/li&gt;
	&lt;li&gt;Number of referenced articles&lt;/li&gt;
	&lt;li&gt;Number of undefined entries&lt;/li&gt;
	&lt;li&gt;Number of active contributors in this period&lt;/li&gt;
