The Collaborative Organization of Knowledge: Source Code

  • 1. Athens University of Economics and Business


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.

In the above paper, a longitudinal study of Wikipedia's evolution shows that although Wikipedia'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's evolution also demonstrates the creation of a large real world scale-free graph through a combination of incremental growth and preferential attachment.
