3WNews: Who, Where, and When in News Video

We describe 3WNews as a novel system for browsing news video by the people (who) and locations (where) appearing in the footage as well as the time (when) of news events. The people names, locations, and time expressions are recognized from video transcript and their ambiguous references are resolved. As a key advantage, 3WNews distinguishes the people and locations that actually appear in the video from those merely mentioned in the transcript, and uses them as (better) indexes for browsing. It also supports browsing of news video by event time instead of broadcasting time.
