Abstract. We hypothesize that the variance in volume of high-velocity queries
over time can be explained by observing that these queries are formulated in re-
sponse to events in the world that users are interested in. Based on it, this paper
describes a system, ZED, which automatically finds explanations for high ve-
locity queries, by extracting descriptions of relevant and temporally-proximate
events from the news stream. ZED can thus provide a meaningful explanation of
what the general public is interested in at any time. We evaluated performance
of several variant methods on top velocity "celebrity name" queries from Yahoo,
using news stories from several sources for event extraction. Results bear out the
