NIST HOSTS TOPIC DETECTION AND TRACKING (TDT) WORKSHOP ON TEXT ORGANIZATION.
The TDT program develops technologies that search, organize, and structure news-oriented textual materials from a variety of broadcast news media in both the English and Mandarin languages. The research-driven program uses controlled laboratory simulations of hypothetical systems to test the efficacy of potential technologies to access the continuously flowing information that is available from news-producing entities.
In earlier studies reported at last years TDT meeting, research showed that it was possible to track and organize events in news data even though the data was multilingual. The TV and radio broadcasts were transcribed using automatic speech recognition, and the Mandarin text was converted to English using COTS Mandarin-to-English software.
The focus of TDT changed in 2000 to the development of core techniques that organize news data. A second shift was to bring more of the real world into the evaluation by requiring TDT systems to operate on broadcast news audio data that has been transcribed, translated, and segmented into stories without human intervention.
