Speech Recognition And Information Retrieval:
(January 2004)Abstract
University is creating large digital libraries of
video and audio data available for full content
retrieval by integrating natural language
understanding, image processing, speech recognition and
information retrieval. These digital video libraries
allow users to explore multi-media data in depth as
well as in breadth. The Informedia system automatically
processes and indexes video and audio sources and
allows selective retrieval of short video segments
based on spoken queries. Interactive queries allow the
user to retrieve stories of interest from all the
sources that contained segments on a particular topic.
Informedia will display representative icons for
relevant segments, allowing the user to select
interesting video paragraphs for playback.
