IntroductionTopic 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. DataThe TDT2 Audio Corpus contains a total of 1,036 waveform files. Each file is a complete single-channel recording of 30- or 60-minute broadcast, which has been digitized at a sample rate of 16 KHz using 16-bit samples. The four broadcast sources represented in the corpus are as follows:
