The Discreet Charm of Meta

Dr. Frank Nack CWI, Amsterdam, The Netherlands
In dynamic environments, such as web-based cultural heritage sites, where neither the individual user requirements nor the requested material can be predicted in advance, an automated presentation generation process is required. For that, however, the system relies on semantic, episodic, and technical representation structures that provide full experience to the user by means of montage. Such constructivistic needs of new media require more than characterizing audio-visual information on a perceptual level using objective measurements, such as those based on image or sound processing or pattern recognition. These retrospective technologies understand media rather from the point of view of automatically index multimedia information.
Though machine-generated metadata is cheap to produce, it is insufficient because it s exclusively organized around the media structures? sensory surfaces that is, the physical features of an image, or video, or audio stream. There is lots of evidence, however, that a great deal of required annotation can be provided by manual labour. In this talk we investigate the notion of individual and purpose-driven audio-visual media annotation during the production process. The aim is to make use of human activity to extract the significant syntactic, semantic and semiotic aspects of the media content as well as the related process, which then can be transformed into formal descriptions. The resulting descriptions form a conceptual information space, in which authors are semantically supported in their creative efforts to generate, manipulate, and exchange information. The approach is demonstrated with examples mainly taken from encyclopaedic spaces from domains such as of theory, history, and anthropology of film or cultural heritage, as provided by museums for the fine arts.

Semantic Web and Knowledge Services is...
Our research in the Semantic Web area looks at the potentials of fusing together advances in a range of disciplines, and applying them in a systemic way to simplify the development of intelligent, knowledge-based web services and to facilitate human access and use of knowledge available on the web. For instance, we are exploring ways in which tnatural language interfaces can be used to facilitate access to data distributed over different repositories. We are also developing infrastructures to support rapid development and deployment of semantic web services, which can be used to create web applications on-the-fly. We are also investigating ways in which semantic technology can support learning on the web, through a combination of knowledge representation support, pedagogical theories and intelligent content aggregation mechanisms. Finally, we are also investigating the Semantic Web itself as a domain of analysis and performing large scale empirical studies to uncover data about the concrete epistemologies which can be found on the Semantic Web. This exciting new area of research gives us concrete insights on the different conceptualizations that are present on the Semantic Web by giving us the possibility to discover which are the most common viewpoints, which viewpoints are mutually inconsistent, to what extent different models agree or disagree, etc...
Our aim is to be at the forefront of both theoretical and practical developments on the Semantic Web not only by developing theories and models, but also by building concrete applications, for a variety of domains and user communities, including KMi and the Open University itself.
