We describe a demonstration system built upon Topic Detection and Tracking (TDT) technology.The demonstration system monitors a stream of news stories, organizes them into clusters that represent topics, presents the clusters to a user, and visually describes the changes that occur in those clusters over time.A user may also mark certain clusters as interesting, so that they can be "tracked" more easily.
