TDT4 Multilingual Broadcast News Speech Corpus was developed by the Linguistic Data Consortium (LDC) with support from the DARPA TIDES (Translingual Information Detection, Extraction and Summarization) Program. This release contains the complete set of American English, Modern Standard Arabic and Mandarin Chinese broadcast news audio used in the 2002 and 2003 Topic Detection and Tracking technology evaluations. The transcripts corresponding to the audio contained in this release, along with newswire data and topic relevance annotations, can be found in LDC Publication LDC2005T16, TDT4 Multilingual Text and Annotations.
Topic Detection and Tracking (TDT) refers to automatic techniques for finding topically related material in streams of data such as newswire and broadcast news. Evaluation tasks in 2002 and 2003 included the segmentation of a news source into stories, the tracking of known topics, the detection of unknown topics, the detection of initial stories on unknown topics, and the detection of pairs of stories on the same topic.
Please examine these wave files for an example of this corpus.
