Mass-Scale Argumentation
This research program aimed to lay the foundations for a world-wide web of annotated arguments, which would allow people to navigate arguments all over the Web. For instance, if you are unsure of the assumptions behind a statement made in an article or piece of news, you would be able to navigate evidence supporting it, as well as the counter-arguments that undermine it, even if these are located elsewhere on the Internet. We articulated this vision, and proposed some semantic annotation technologies that would facilitate it. Building on these ideas, others have grown a full research program to realize this "worldwide argument web" (see this recent survey for an overview).
