  "abstract": "<p>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.</p>\n\n<ul>\n\t<li>Diomidis Spinellis and Panagiotis Louridas. The collaborative organization of knowledge. Communications of the ACM, 51(8):68&ndash;73, August 2008. (<a href=\"\">doi:10.1145/1378704.1378720</a>)</li>\n</ul>\n\n<p>In the above paper, a longitudinal study of Wikipedia&#39;s evolution shows that although Wikipedia&#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&#39;s evolution also demonstrates the creation of a large real world scale-free graph through a combination of incremental growth and preferential attachment.</p>\n\n<p>Though this data set you can download the processed results.
