A Formal Model for Domain Knowledge Representation and Reasoning using MPEG-7 Constructs

چکیده
The use of domain knowledge in semantic audiovisual content descriptions enhances the functionality and effectiveness of the multimedia applications. However, the dominant standard for audiovisual content description today (MPEG-7) does not describe a formal mechanism for the systematic integration of domain knowledge and reasoning capabilities in the MPEG-7 descriptions. The specification of a formal model for domain knowledge representation and reasoning using the MPEG-7 constructs is of paramount importance for exploiting domain knowledge in order to perform semantic processing of the multimedia content. In this paper we present a formal model that allows the systematic representation of domain knowledge using MPEG-7 constructs and its exploitation in reasoning. The formal model that we describe exploits exclusively MPEG-7 constructs, and the descriptions that are structured according to the model are completely within the MPEG-7 standard.

متن کاملTowards an Ontology for MPEG-7 Semantic Descriptions
Multimedia resources may be described using several metadata standards, MPEG-7 being the most comprehensive among those standards. MPEG-7 provides different tools to describe any multimedia content. Semantic Descriptor Scheme is one of them, which is used to describe the semantics of the content in terms of Events, Objects, Concepts, Places, Time and Abstraction. Since there is no hard and fast...
متن کاملCombined Domain Specific and Multimedia Ontologies for Image Understanding
Knowledge representation and annotation of multimedia documents typically have been pursued in two different directions. Previous approaches have focused either on low level descriptors, such as dominant color, or on the content dimension and corresponding manual annotations, such as person or vehicle. In this paper, we present a knowledge infrastructure to bridge the gap between the two direct...
