Topic Detection and Tracking (TDT) refers to automatic techniques for
finding topically related material in streams of data such as newswire and
broadcast news. The TDT2 corpus was created to support three TDT2 tasks:
find topically homogeneous sections (segmentation), detect the occurrrence
of new events (detection), and track the reoccurrencce of old or new events
(tracking). For further information on TDT2 please visit our TDT2 Information Pages.
