TDT2 (Topic Detection and Tracking) Careful Transcription Audio was developed by the Linguistic Data Consortium (LDC) and contains English broadcast news audio recordings collected by LDC in 1998. Corresponding transcripts are available in TDT2 Careful Transcription Text LDC2000T44.

Topic Detection and Tracking 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 occurrence of new events (detection) and track the reoccurrence of old or new events (tracking).


This publication contains 1998 broadcasts from the following sources: ABC News, Cable News Network, Public Radio International and Voice of America.
