Community and Media: Concepts and Systems

Yiwei Cao
RWTH Aachen University

Date: December 17, 2007 (Monday)
Time: 10:30 - 11:30 am
Venue: SCT909, Cha Chi Ming Science Tower, Ho Sin Hang Campus

A general question addressed in design and realization of community information systems esp. for the domain of cultural heritage management is how to support non-technical communities with modern information technologies and media. Communities could be shaped or even changed via media. Nowadays, communities are empowered to create and share media even more easily with social software and Web 2.0. However, with the increase of multimedia quantity, the main challenges remain to be the quality of the multimedia information processing related to information modeling, semantic multimedia retrieval, and community-specific information system development and deployment. In this talk, I will first briefly introduce the media theoretical approaches applied to understand the ongoing media processes better. I will then discuss data modelling and database technologies including XML databases for multimedia metadata such as the advanced multimedia metadata standard MPEG-7. Furthermore, a conceptual framework namely Virtual Campfire will be presented to demonstrate how multimedia information for cultural heritage management is organized and shared across diverse communities on various (mobile) platforms. Its web services and community engine can be flexibly and easily applied onto different multimedia repositories for a rapid prototyping and information integration. Within Virtual Campfire cultural heritage communities’ requirements are considered and fulfilled, while multimedia is (re-)contextualized for different use purposes such as multimedia storytelling. Current research and future work in several EU and German Research Foundation projects will be discussed.
