In this paper, we present MAP2OWL, a software tool that allows the development of OWL ontologies as concept maps. MAP2OWL uses existing OWL constructs to represent conceptual maps; in this way, domain experts develop ontolologies in a graphical conceptual way, not having to be aware of syntactic matters, or issues related to interfaces that were designed for knowledge engineers. MAP2OWL facilit...

Seven years on from OWL becoming a W3C recommendation, and two years on from the more recent OWL 2 W3C recommendation, OWL has still experienced only patchy uptake on the Web. Although certain OWL features (like owl:sameAs) are very popular, other features of OWL are largely neglected by publishers in the Linked Data world. This may suggest that despite the promise of easy implementations and t...

OWL is the new ontology language produced by the W3C Web Ontology Working Group. OWL is thus poised to be a major formalism for the design and dissemination of ontology information, particularly in the Semantic Web. OWL has influences from several communities, including the RDF community, the Description Logic community, and the frame community. These influences resulted in a wide variety of re...

Decision making is a big topic in Intelligence, Defense, and Security fields. However, very little work can be found in the literature about ontology languages that simultaneously support decision making under uncertainty, abstractions/generalizations with first-order expressiveness, and forward/backward compatibility with OWL—a standard language for ontologies. This work proposes PR-OWL Decisi...

In this article we present the RDF/OWL LexiRes Tool that supports authors using RDF/OWL structures in editing and structuring ontologies. In contrast to standard ontology editors like e.g. Protégé [20], this tool was especially designed to support the use of multilingual resources, and in particular the use of RDF/OWL EuroWordNet word senses and translations [4]. Related concepts can be searche...

The Web Ontology Language (OWL) defines three classes of documents: Lite, DL and Full. All RDF/XML documents are OWL Full documents, some OWL Full documents are also OWL DL documents, and some OWL DL documents are also OWL Lite documents. This paper discusses parsing and species recognition – that is the process of determining whether a given document falls into the OWL Lite, DL or Full class. ...

Web Ontology Language (OWL) [5] can be seen as an extension of Resource Description Framework (RDF). The primary exchange syntax for OWL is RDF/XML, and every OWL ontology can be represented as an RDF graph. But there is no standard query language specifically for OWL ontologies. The most commonly used Semantic Web query language is SPARQL [7], which is intended to be used for RDF. Roughly spea...

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. SWC...
