Patching syntax in owl ontologies

by Sean Bechhofer, Raphael Volz - Proceedings of the 3rd International International Semantic Web Conference , 2004
"... Abstract. An analysis of OWL ontologies represented in RDF/XML on the Web shows that a majority are OWL Full. In many cases this may not be through a desire to use the expressivity provided by OWL Full, but is rather due to syntactic errors or accidental misuse of the vocabulary. We present a “rogue ..."

Publishing OWL ontologies with Presto

by Er Deleon, Michel Dumontier
"... Abstract. Publishing RDF/OWL ontologies on the Semantic Web typically starts by placing the document in a web accessible location and ends with redirects of ontological components (classes, properties, individuals) to that the document. Unfortunately, this is seldom sufficient for expressive OWL ont ..."

Converting Classifications into OWL Ontologies

by Fausto Giunchiglia, Ilya Zaihrayeu, Feroz Farazi
"... Abstract. Classification schemes, such as the DMoZ web directory, provide a convenient and intuitive way for humans to access classified contents. While being easy to be dealt with for humans, classification schemes remain hard to be reasoned about by automated software agents. Among other things, t ..."

, this hardness is conditioned by the ambiguous nature of the natural language used to describe classification categories. In this paper we describe how classification schemes can be converted into OWL ontologies, thus enabling reasoning on them by Semantic Web applications. The proposed solution is based on a

Consistent Evolution of OWL Ontologies

by Peter Haase And, Peter Haase, Ljiljana Stojanovic , 2005
"... Support for ontology evolution is extremely important in ontology engineering and application of ontologies in dynamic environments. A core aspect in the evolution process is the to guarantee consistency of the ontology when changes occur. In this paper we discuss the consistent evolution of OWL ..."

Temporal Extension of OWL Ontologies

by Sudeep Marwaha, Punam Bedi - International Journal of Information Technology , 2007
"... Abstract—Ontologies play an important role in semantic web applications and are often developed by different groups and continues to evolve over time. The knowledge in ontologies changes very rapidly that make the applications outdated if they continue to use old versions or unstable if they jump to ..."

to new versions. Temporal frames using frame versioning and slot versioning are used to take care of dynamic nature of the ontologies. The paper proposes new tags and restructured OWL format enabling the applications to work with the old or new version of ontologies. Gene Ontology, a very dynamic

An OWL Ontology for Quantum Mechanics

by Marcin Skulimowski
"... Abstract. An OWL ontology for quantum mechanics is presented in short. The motivation for its development, structure and characteristic features are depicted. In particular, some essential concepts from the ontology are described. Finally, some problems encountered during the development of the onto ..."

DEBUGGING AND REPAIR OF OWL ONTOLOGIES

by Aditya Kalyanpur , 2006
"... With the advent of Semantic Web languages such as OWL (Web Ontology Language), the expressive Description Logic SHOIN is exposed to a wider audience of ontology users and developers. As an increasingly large number of OWL ontologies become available on the Semantic Web and the descriptions in the on ..."

evolution of OWL ontolo-gies. We present a model for the semantics of change for OWL ontologies, con-sidering structural, logical, and user-defined consistency. We introduce resolution strategies to ensure that consistency is maintained as the ontology evolves. 1

Literate, Active OWL Ontologies

by Bijan Parsia
"... Abstract. OWL ontologies are complex computational artifacts that are intimately connected with conceptual information and with application issues that are not easily explicable in the context of an OWL document. In this paper, drawing inspiration from literate programming and active essays, I propo ..."

Debugging owl ontologies

by Bernardo Cuenca Grau, Bijan Parsia, Evren Sirin, Aditya Kalyanpur , 2005
"... Abstract. Modularity in ontologies is key both for large scale ontology development and for distributed ontology reuse on the Web. In this paper, we address the problem of determining and retrieving the subset of an ontology that captures the essential meaning of a given entity in the ontology. Howe ..."
