An automatic indexing system for television newscasts

The demonstration will be about an integrated system for the acquisition, automatic annotation and Web publication of television broadcast news programmes named ANTS (Automatic Newscast Transcription System). The system consists of several analysis components integrated in a unified architecture. Users have the possibility to access a large daily-growing database of news stories from the main national channels, all identified, categorised and published in a fully automatic way. The system identifies story boundaries, extracts texts from spoken content, classifies stories by subject and links external relevant information coming from the Web. ANTS integrates several heterogeneous analysis components in a performant and ready-for-production environment, capable of elaborating many hours of material per day without significant service drops and with sufficiently good accuracy for industrial employment.
