In this article we argue that for the automatic generation of adaptive multimedia presentations we are in need of expandable, adaptable style descriptions which provide both high-level conceptual and low-level feature extraction information. Only the combination of both facilitates the retrieval of adequate material and its user-centred presentation. We discuss the requirements for an adaptable Web-based environment for museums presenting visual artefacts. We then present the framework of our prototype multimedia generation environment which transforms a high-level user query into a concrete multimedia final-form encoding that is playable on an end-users'' platform. We describe the underlying architecture and provide a working example.

The role of high-level and low-level features in style-based retrieval and generation of multimedia presentations
In this paper we argue that the automatic generation of dynamic multimedia presentation requires both low-level collections of objective measurements for media units representing prototypical style elements, and high-level conceptual descriptions ...
Retrieval in multimedia presentations
In this paper we discuss issues concerning the consistent retrieval of parts of multimedia presentations from multimedia repositories. We introduce a class of multimedia presentations made of independent and synchronized media and discuss retrieval ...
From Low-Level Features to High-Level Semantics: Are We Bridging the Gap?
ISM '05: Proceedings of the Seventh IEEE International Symposium on MultimediaThe performance of a content-based information retrieval (CBIR) system is very subjective and hence user-dependent. To the user, similarity between objects in the database is often highlevel and semantic. However, features extracted from objects ...
