 Within the BOEMIE project, and in collaboration with the Image, Video and Multimedia Laboratory (IVML) of NTUA, an OWL-DL ontology-based framework has been developed to support the synergistic utilization of semantics extraction from multimedia and ontology evolution in a bootstrapping process. The latter involves the continuous extraction of information from multimedia documents in order to populate and enrich the ontologies, and the deployment of these ontologies to enhance the robustness and accuracy of extraction. The developed framework covers media specific (including MPEG-7 descriptors and structural decomposition) and domain-specific (including athletic events and geographical information) aspects, as well as their conceptual linking under the so called Multimedia Semantic Model.
