Digging for Competitve Information in Audiovisual (AV) Information Sources

An increasing number of competitive information is published in audio visual formats, e.g. video recordings from conferences, workshops, investor roadshows, company portraits, and marketing events. While companies might have well established procedures for collecting and analyzing textual sources, comparable procedures for videos have not yet been established. In most cases these videos are kept in company archives, or are published on commercial platforms like YouTube, Vimeo or on conference website. A systematic search in these treasure vaults is however difficult.

 

Searching manually for AV-content is time-consuming, if not impossible, because the content can neither be searched as full-text nor is it possible to skip through all findings of a given search term – as done when searching in full text sources. Finally natural speech is often even more ambiguous than written words, i.e. a given search term can actually have varying meanings depending on the context it is used in.

 

Speech recognition for the creation of audio transcripts is a key to making video content searchable. Semantic analysis and visual concepts allow an even more detailed and user friendly explorative search experience.

Videos can even be searched and accessed on a segment level and a cross-lingual mapping (German-English) of the semantic knowledge base enables videos to be searched across multiple languages.

This session will highlight state-of-the-art approaches to digging into these important audiovisual information sources.

As an example the audiovisual portal of the Leibniz Information Centre for Science and Technology (TIB) will be presented in a live demonstration.
