On-Line New Event Detection and Tracking
Research and Development in Information Retrieval, page 37--45. (1998)Abstract
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...
