The evaluation-driven project advances the state of the art in technologies that organize events in simultaneously collected streams of multilingual news data. The evaluation is open to all interested participants, (see the contacts below).This year's project defines five research applications: Story Segmentation, Topic Tracking, Topic Detection, First Story Detection, and Link Detection. The Evaluation Plan contains descriptions of the applications and the protocols for running and evaluating them. Please read and understand this document before developing a TDT system for the evaluation. EVALUATION STATUSThe evaluation has begun as of September 13, 2000 and results are due October 10, 2000.
