Enabling multimedia metadata interoperability by defining formal semantics of MPEG-7 profiles
TLDR
This paper proposes an approach for expressing semantics explicitly by formalizing the semantic constraints of a profile using ontologies and rules, thus enabling interoperability and automatic use for MPEG-7 based applications.Abstract:
MPEG-7 can be used to create complex and comprehensive metadata descriptions of multimedia content. Since MPEG-7 is defined in terms of an XML schema, the semantics of its elements have no formal grounding. In addition, certain features can be described in multiple ways. MPEG-7 profiles are subsets of the standard that apply to specific application areas, which can be used to reduce this syntactic variability, but they still lack formal semantics. In this paper, we propose an approach for expressing semantics explicitly by formalizing the semantic constraints of a profile using ontologies and rules, thus enabling interoperability and automatic use for MPEG-7 based applications. We demonstrate the feasibility of the approach by implementing a validation service for a subset of the semantic constraints of the Detailed Audiovisual Profile (DAVP)read more

Semantic Integration and Retrieval of Multimedia Metadata
TL;DR: A complete and automatic mapping of the whole MPEG-7 standard to OWL has been set up based on XML2OWL mapping and XML2RDF mapping to move multimedia metadata to semantic web.
Adding Formal Semantics to MPEG-7: Designing a Well-Founded Multimedia Ontology for the Web
TL;DR: This work derives a number of requirements for specifying a formal multimedia ontology, including: compatibility with MPEG-7, embedding in foundational ontologies, and modularisation including separation of document structure from domain knowledge.
MPEG-7 based Multimedia Ontologies: Interoperability Support or Interoperability Issue?
TL;DR: Four independent approaches to build a multimedia ontology based on the MPEG-7 standard are described and the similarities and differences between them are discussed.

TL;DR: This paper discusses how the philosophy and features of OWL can be traced back to these older formalisms, with modifications driven by several other constraints on OWL.

Description logic programs: combining logic programs with description logic
TL;DR: It is shown how to interoperate, semantically and inferentially, between the leading Semantic Web approaches to rules and ontologies and define a new intermediate knowledge representation contained within this intersection: Description Logic Programs (DLP), and the closely related Description Horn Logic (DHL).

Combining Horn rules and description logics in CARIN
TL;DR: It is shown that in general, the reasoning problem for recursive carin - A LCNR knowledge bases is undecidable, and the constructors of ALCNR causing the undecidability is identified.
