Business economics - Information Management, grade: 1,0, University of
Graz, language: English, abstract: The Semantic Web has become reality
over the past couple of years. While certain practical topics-such as
interoperability, etc.-have at least partially been addressed,
scalability and expressivity issues regarding the utilisation of
multimedia metadata on the Semantic Web are still widely neglected.
However, existing Web (2.0) applications handling millions of multimedia
assets are starting to take advantage of Semantic Web technologies. This
work contributes to design decisions regarding scalable and smart
multimedia applications on the Semantic Web. Based on an analysis of
practical issues-stemming from diverse projects and activities the
author has participated in over the past four years-three areas have
been identified, namely (i) performance and scalability issues on the
data access level, (ii) the effective and efficient representation of
multimedia content descriptions, and (iii) the deployment of multimedia
metadata on the Semantic Web. The three research areas have as its
common base the trade-off between expressivity and scalability. We
present our findings regarding scalable, yet expressive Semantic Web
multimedia applications in a number of practical settings and discuss
future directions, such as interlinking multimedia.
