BUILDING SCALEABLE AND SMART MULTIMEDIA APPLICATIONS ON THE SEMANTIC WEB

In the design and implementation of Semantic Web multime- dia applications (SWMA), real-world requirements have not yet been widely addressed. This work contributes to build- ing scaleable and smart SWMA. Regarding scalability and expressivity, three main areas are researched: (i) processing of metadata sources on the RDF-level, (ii) formal represen- tation of multimedia vocabularies, and (iii) multimedia meta- data deployment issues. 1. MOTIVATION The cornerstones of using multimedia metadata (M3) on the Semantic Web has been extensively researched (1). While certain issues, as interoperability, etc. have been addressed, the practical utilisation of M3 on the Semantic Web w.r.t. scalability and expressivity is still neglected. Studer et.al. (2) recently claimed a challenge w.r.t. the expressivity-scalability trade-off of reasoning over declarative knowledge. Existing Web applications handling millions of multimedia assets are starting to take advantage of Semantic Web technologies (3).
