On-line New Event Detection and Tracking. Allan, J., Papka, R., & Lavrenko, V. In In Proceedings of the 21st Annual International ACM SIGIR Conference on Research and Development in Information Retrieval, pages 37–45, 1998. abstract bibtex We define and describe the related problems of new event detection and event tracking within a stream of broadcast news stories. We focus on a strict on-line setting—i.e., the system must make decisions about one story before looking at any subsequent stories. Our approach to detection uses a single pass clustering algorithm and a novel thresholding model that incorporates the properties of events as a major component. Our approach to tracking is similar to typical information filtering methods. We discuss the value of "surprising" features that have unusual occurrence characteristics, and briefly explore on-line adaptive filtering to handle evolving events in the news. New event detection and event tracking are part of the Topic Detection and Tracking (TDT) initiative. 1 Introduction The problems discussed in this study are new event detection and event tracking. The goal of those tasks is to monitor a stream of broadcast news stories so as to determine the relationships between ...
