Abstract

The Topic Detection and Tracking (TDT) research program has been running for five years, starting with a pilot study and including yearly open and competitive evaluations since then. In this chapter we define the basic concepts of TDT and provide historical context for the concepts. In describing the various TDT evaluation tasks and workshops, we provide an overview of the technical approaches that have been used and that have succeeded.
