Wikipedia Source Visualization
Our research studies where information in Wikipedia comes from, a characteristic we call geoprovenance. We focus on the four million Wikipedia articles about places that, along with information such as TripAdvisor reviews and geotagged flickr images, constitutes the rising class of information renowned geographer Michael Goodchild calls volunteered geographic information (VGI). As some have argued (Kitchin and Dodge, 2011; Graham et al., 2013), VGI does not just represent the world, but also becomes part of the world. It forms layers of code and information that augment everyday activities: it shapes where we go, what we do, and how we perceive and understand the world that we live in. The study of geoprovenance, which we undertake here, helps us understand the perspectives, gaps, and inequalities in VGI repositories. More information and demo
