Semantic interoperability is usually provided inopen environments through standards and domain ontologies.The dominant standards for multimedia contentand service descriptions are MPEG-7 and MPEG-21. The MPEG-7 Semantic DS has powerful semanticdescription capabilities and supports using semanticentities specified in domain ontologies in multimediacontent descriptions. However, the MPEG-7/21 UsageEnvironment allows neither the specification of semanticuser preferences nor the exploitation of domainknowledge and MPEG-7 semantic metadata descriptions.In addition, the users cannot explicitly specify, inthe hierarchical MPEG-7/21 filtering and search preferences,the boolean operators that should be usedduring content filtering to combine the hierarchy components.We think these as serious limitations and wepropose a hierarchical semantic user preference modelthat allows for the explicit specification of booleanoperators. Then, we present the application of themodel in MPEG-7/21 and the model implementationwithin the DS-MIRF framework.
