ABSTRACT
|
| Knowledge representation and annotation of multimedia documents typically have been pursued in two different directions. Either previous approaches have focused on low level descriptors, such as dominant color, or they have focused on the content dimension and corresponding manual annotations, such as person or vehicle. In this paper, we present a knowledge infrastructure and a software environment for annotation to bridge between the two directions. Ontologies are being extended and enriched to include low-level audiovisual features, descriptors and behavioural models. Additionally, a tool is presented that allows for linking low-level MPEG-7 visual descriptions to conventional Semantic Web ontologies and annotations. In this way, we construct ontologies that include prototypical instances of high-level domain concepts together with a formal specification of corresponding visual descriptors. Thus, we formalize the interrelationship of high and low-level multimedia concept descriptions, allowing for new media content analysis and reasoning, employing a genetic algorithm that makes use of this knowledge.
