Linking the tele-TASK video portal to the semantic web

Abstract

Audiovisual data have gained an enormous and ever-growing popularity in the world wide web. Also a growing number of educational content such as, e.g., lecture recordings or audiovisual learning material can be found recently. But, pinpoint and exhaustive retrieval of audiovisual e-learning content in the web is rather difficult as well as automated metadata interchange and integration. We demonstrate a use-case of metadata integration for audiovisual learning resources by complementing web pages of a video lecture portal with semantic RDFa annotations giving way to automated access and universal retrievability.
