Learning about the Social Networks behind Wiki

Reference: Korfiatis, Poulos and Bokos, “Evaluating authoritative sources using social networks: an insight from Wikipedia”, Online Information Review Vol. 30 No. 3, 2006 pp. 252-262

Two Layers of Network

(1) The articles network.
Every article in the Wikipedia contains references to other articles as well as external references. A set of links used for classification purposes is also available in most of the active articles of the encyclopedia. Every article represents a vertex in the article network and the internal connections between the article edges of the network.

(2) The contributors network.

Wikipedia is a collaborative writing effort, which means that an article has multiple contributors. We assume that a contributor establishes a relationship with another contributor if they work on the same article. In the resultant signed network, a vertex represents each contributor, and their social ties (positive or negative) are represented by an edge denoting the sequence of their social interaction.Visualization of the Social Network of contributors behind the article "Immanuel Kant"

...And of course, I had already mentioned Chris Harrison's WikiViz Project. Talk about beautiful graphs!

You can also have a look at the Clusterball Project. Dont miss the movie.
