The European Commission recently became interested in mapping digital social innovation in Europe. In order to understand this rapidly developing if little known area, a visual and interactive survey was made in order to crowd-source a map of digital social innovation, available at http://digitalsocial.eu. Over 900 organizations participated, and Linked Data was used as the backend with a number of valuable advantages. The data was processed using SPARQL and network analysis, and a number of concrete policy recommendations resulted from the analysis.
