Multimedia Ontologies

The development and maintenance of large multimedia databases has attracted much attention nowadays from companies and organizations that held multimedia content (archives, broadcast companies, radio and TV channels, etc.). the goal is to bypass the ineffective and time-consuming process of manual searching and retrieval of multimedia content and use computers to make the content easy to be found and accessible to other parties. Thus, two critical points are identified in making the above goal a reality; effective representation as well as effective retrieval and exploitation of multimedia content. For accomplishing the above goal researchers have started to use ontologies in the field of multimedia in order to construct machine-understandable, descriptive versions of the multimedia content based on multimedia ontologies. In this paper, we present multimedia ontology characteristics, its construction and some existing multimedia ontologies.
