Wikipedia is without question one of the most succesful examples of social machines. Based on the collaborative contribution of millions of editors, Wikipedia has come impressively far towards achieving its ambition to make the sum of human knowledge available to every person on the planet.
Our lines of work on the Wikipedia project has included analysis of WikiProjects, documentation of the real-time Wikipedia edit stream, and application of the Transcendental Information Cascade model to construct alternative linking structures between Wikipedia articles. We have also explored the potential for using Wikidata to reduce factual inconsistencies across Wikipedia versions in different languages.
