Multilingual Topic Detection and Tracking: Successful Research Enabled by Corpora and Evaluation
Proceedings of the Second International Conference on Language Resources and Evaluation (LREC 2000)
Abstract
Topic Detection and Tracking (TDT) refers to automatic techniques for locating topically related material in streams of data such as newswire and broadcast news. DARPA-sponsored research has made enormous progress during the past three years, and the tasks have been made progressively more difficult and realistic. Well-designed corpora and objective performance evaluations have enabled this success.
