3 G. Wu M. Harrigan P. Cunningham 2011 The 22nd Irish Conference on Artificial Intelligence and Cognitive Science (AICS'11) 166–173 Wikipedia works because of the many eyes idea. Good Wikipedia pages are authoritative sources due to the collaboration of a number of knowledge contributors. In this paper we explore the hypothesis that the extent of this collaboration for a specific article can be assessed by looking at the edit graph associated with that article, i.e. the network of contributors and articles. As a first step in this direction we show that different regions of Wikipedia have very different edit graph motif profiles. We show, for example, that articles on sociologists (a well-curated region of Wikipedia) are very different to articles on footballers in the English Premiership.
