role in Semantic Web research, with a large number of research efforts underway. Foundations of Fuzzy Logic and Semantic Web Languages provides a rigorous and succinct account of the mathematical methods and tools used for representing and reasoning with fuzzy information within Semantic Web languages. The book focuses on the three main streams of Semantic Web languages: • Triple languages RDF ...

It is common for information exchange between heterogeneous systems to be syntactically correct but fail to achieve its intended purpose due to semantic mismatches. NATO research group IST-094 is developing a framework to facilitate semantic interoperability. We will show a live demonstration of one possible approach to implementing a message translation broker, following the Semantic Interoper...

The reference reconciliation problem consists in deciding whether different identifiers refer to the same data, i.e., correspond to the same world entity. The L2R system exploits the semantics of a rich data model, which extends RDFS by a fragment of OWL-DL and SWRL rules. In L2R, the semantics of the schema is translated into a set of logical rules of reconciliation, which are then used to inf...

TOOL PRESENTATION: Rule languages and inference engines incorporate reasoning capabilities to Web information systems. This demonstration paper presents a tool for the development of rulebased applications for the Web based on OWL and SWRL ontologies. The tool applies a model-driven approach to an ontology representing a domain conceptualization and inference model of the problem domain. It aut...

In this paper we present an approach which aims to support learners in general and environmental decision makers in particular, towards effective decision making in maritime environmental pollution via education and awareness of specific maritime environmental pollution policies. We build on previous work concerning the automatic construction of multiple-choice questions from ontologies (automa...

The paper presents a novel approach which aims to support the training of decision makers in maritime environmental pollution policies via an intelligent tutoring system that focuses on the automatic generation of self-assessment material. More specifically, the paper reports on the automatic construction of multiple-choice question tests from knowledge bases i.e. domain ontologies, instances, ...

This paper proposes a semantic framework built on multidimensional ontological matrices for the design of adaptive systems. The core of the framework is composed by three matrices whose different planes contain the ontological representation of different types of knowledge. On these planes we represent user features, her actions, context, device, content domain, adaptation goals and methods. Th...

The Extremely Annotational RDF Markup, a.k.a. EARMARK, is an OWL 2 DL ontology that defines document meta-markup. It is an ontologically precise definition of markup that instantiates the structure of a text document as an independent OWL document outside of the text string it annotates, and through appropriate OWL and SWRL characterizations it can define organizations such as trees or graphs a...

In this paper we introduce a solution for the problem of the design-time verification of cross-organizational business processes. The configuration of the processes can be checked in order to examine whether it fulfills a certain set of business level requirements. A formal Ontology in OWL for these kinds of processes is provided, so logic mechanisms for the verification are applied. The busine...

Detailed road maps are essential for efficient routing of vehicles. However, available data on roads is not always sufficient to support efficient routing, especially in the domain of agricultural vehicles, where route networks are not maintained by official mapping agencies. Efficient route planning can help reducing the cost of agricultural operations such as harvesting. We propose an approac...
