Resources

The aceMedia project offers a resource for interested organizations to publish multimedia ontologies so that there is a collective benefit from each other's work. This initiative was a result of the MM&SW workshop held on 29 May as part of ESWC05, where there was general agreement that this could be useful to researchers working in the integration of multimedia and Semantic Web technologies domain to share already developed multimedia ontologies as a first step towards closer collaborative development in future.

If you would like to join us in this initiative, please send your documents to Yiannis Kompatsiaris (ikom@iti.gr) containing the actual ontologies, along with a short description regarding the structure, format and intended application. Please add links to a contact person and related materials (e.g. papers, presentations) useful to someone interested in your ontologies.

aceMedia Visual Descriptor Ontology v9.0

The Visual Descriptor Ontology (VDO) developed within the aceMedia project for semantic multimedia content analysis and reasoning, contains representations of MPEG-7 visual descriptors and models Concepts and Properties that describe visual characteristics of objects. By the term descriptor we mean a specific representation of a visual feature (color, shape, texture etc) that defines the syntax and the semantics of a specific aspect of the feature. For example, the dominant color descriptor specifies among others, the number and value of dominant colors that are present in a region of interest and the percentage of pixels that each associated color value has.
Although the construction of the VDO is tightly coupled with the specification of the
MPEG-7 Visual Part, several modifications were carried out in order to adapt to the
XML Schema provided by MPEG-7 to an ontology and the data type representations available in RDF Schema.
