Tool: Mapping Collaborative Work
History Flow, a data visualization project developed at IBM's Watson Research center, is a free-for-download tool that illustrates how collaborative authors work together and construct vast, fluid documents together on wikis. It has been used to track traffic and vandalism on Wikipedia, but its creators, Martin Watternberg and Fernanda Viegas, are now studying how different wiki designs might affect what types of ideas and texts are produced. Because History Flow is still a research experiment, expect bugs -- although users can e-mail their questions and comments and contribute to the further development of this work-in-progress.
