We build tools to allow a community of people to collectively summarize large discussions online and manage knowledge embedded within these discussions.

Large-scale discussions between many participants abound on the internet today. But as these discussions grow to tens of thousands of posts, they become ever more difficult for a reader to digest.

We've developed a workflow called recursive summarization and a prototype system called Wikum that enables a large population of readers or editors to work in small doses to refine out the main points of the discussion. More than just a single summary, our workflow produces a summary tree that enables a reader to explore distinct subtopics at multiple levels of detail based on their interests.
