Current semantic web services lack reusability and conceptual separation between services and goals. We propose a unified architecture based on the principles of WSMF and UPML. We introduce goal- and domain-independent web services. Reuse is achieved through the use of bridges and refiners for...
A general web rule (markup) language has several purposes. It may serve as a lingua franca to exchange rules between different systems and tools. It may be used to express derivation rules for enriching web ontologies by adding definitions of derived concepts or for defining data access...
A technical infrastructure for storing, querying and managing RDF data is a key element in the current semantic web development. Systems like Jena, Sesame or the ICS-FORTH RDF Suite are widely used for building semantic web applications. Currently, none of these systems support the integrated...
The emergence of web standards for representing the semantics of information has enabled a new level of integration of information resources. In this paper we will discuss a number of issues related to semantic integration and the techniques we employed for integrating disparate resources. We...
'Document Web' (XML-based) and 'Semantic Web' (RDF-based) methods are often surprisingly hard to integrate. In this paper, we analyse the role of (RDF) semantics in selecting, structuring and styling (XML) content. We use our analysis to derive a more integrated alternative, based on an XSLT...
