Data management has become a critical challenge faced by a wide array of scientific disciplines in which the provision of sound data management is pivotal to the achievements and impact of research projects. Massive and rapidly expanding amounts of data combined with data models that evolve over time contribute to making data management an increasingly challenging task that warrants a rethinking of...
The current Semantic Web ontology language has been designed to be both expressive for specifying complex concepts and decidable for automated reasoning. In recent years, the Semantic Web Rules Language has been proposed to add more expressiveness to the family of ontology languages. However the inclusion of rules has created new challenges of not only verifying the consistency of an ontology, but...
Semistructured data has become more and more prominent in the fast growing areas of web information technology. XML has been used as a standard format for semistructured data in representing and exchanging information in various applications. However, the lack of formality and verification support in the design of a good semistructured data model may hinder its development. For example, redundant...
As the semantic web is an open, complex and constantly evolving medium, it is the norm, but not exception that information at different sites is incomplete/inconsistent. This poses challenges for the engineering and development of agent systems on the semantic web since autonomous software agents need to understand, process and aggregate this information. Ontology language OWL provides core language...
