Bridging the gap between OWL and Object-Oriented Programming (OOP) languages is an indispensable condition to enable the Object-Oriented Modeling in Software Engineering by OWL. However it is very difficult in case of static OOP languages like Java and C#. We have developed SWCLOS, which is an OWL processor seamlessly built on top of Common Lisp Object System (CLOS), a dynamic OOP language. SWCLOS...
Defeasible reasoning is a rule-based approach for efficient reasoning with incomplete and conflicting information. Such reasoning is useful in many Semantic Web applications, like policies, business rules, brokering, bargaining and agent negotiations. Nevertheless, defeasible logic is based on solid mathematical formulations and is, thus, not fully comprehensible by end users, who often need graphical...
pD* semantics extends the ‘if-semantics’ of RDFS to a subset of the OWL vocabulary. It leads to simple entailment rules and relatively low computational complexity for reasoning. In this paper, we propose a forward-chaining reasoning algorithm to support RDFS entailments under the pD* semantics. This algorithm extends the Sesame algorithm to cope with the pD* entailments. In particular, an optimization...
Triple Space Computing (TSC) is a very simple and powerful paradigm that inherits the communication model from Tuple Space Computing and projects it in the context of the Semantic Web. In this paper, we propose Triple Space Computing as a new communication and coordination framework for Semantic Web and Semantic Web Services. We identify the value added by TSC and propose the overall architecture...
