✦ Synopsis
One important class of online videos is news broadcasts. Most news organizations provide immediate access to topical news broadcasts over the Internet, through RSS streams or podcasts. Until lately, technology has not made it possible for a user to automatically find, within a longer broadcast, the smaller parts that might interest them. Recent advances in both speech recognition systems and natural language processing have led to a number of robust tools that allow us to provide users with quicker and more focused access to relevant segments of one or more news broadcast videos. Here we present an interface for browsing or searching news broadcasts (video or audio) that exploits these new language processing tools to (i) provide immediate access to topical passages within news broadcasts, (ii) browse news broadcasts by events as well as by people, places and organizations, (iii) search for news through a map interface, (iv) browse news by trending topics, and (v) have a brief automatically generated textual characterization of news segments before listening. Our publicly searchable demonstrator currently indexes daily broadcast news content from sources in English, French, Chinese, Arabic, Spanish, Dutch, Russian and Italian.
