Navigating OWL 2 Ontologies Through Graph Projection [chapter]

Ahmet Soylu, Evgeny Kharlamov
2019 Communications in Computer and Information Science  
To this end, in this short paper, we describe an approach for projecting the nonhierarchical topology of an OWL 2 ontology into a graph.  ...  Ontologies are powerful, yet often complex, assets for representing, exchanging, and reasoning over data. Particularly, OWL 2 ontologies have been key for constructing semantic knowledge graphs.  ...  Conclusions In this paper, we presented an approach, together with two example applications, for navigating OWL 2 ontologies by projecting them into graphs through harvesting a set of axioms.  ...

Identifying Potentially Important Concepts and Relations in an Ontology [chapter]

Gang Wu, Juanzi Li, Ling Feng, Kehong Wang
2008 Lecture Notes in Computer Science  
More and more ontologies have been published and used widely on the web. In order to make good use of an ontology, especially a new and complex ontology, we need methods to help understand it first.  ...  Identifying potentially important concepts and relations in an ontology is an intuitive but challenging method.  ...  Acknowledgments We would like to thank all the ontology creators who contributed their ranking results, and all the reviewers for their constructive comments and suggestions.  ...

2021 arXiv   pre-print
We use the Rail Topology Ontology for our rail knowledge graph and plan to extend it by rail infrastructure ontologies derived from existing data exchange standards, since many such standards use the same  ...  This paper describes the ontology and its development method, and discusses its suitability for integrating data of railway engineering systems and other sources in a knowledge graph.  ...  For authoring the ontology and documentation we used Protégé 5.5 [17] , Widoco [10] and the OOPS! ontology scanner [18] . To prepare the figures in this paper we used PlantUML and Graphviz.  ...

OptiqueVQS: A visual query system over ontologies for industry

Ahmet Soylu, Evgeny Kharlamov, Dmitriy Zheleznyakov, Ernesto Jimenez-Ruiz, Martin Giese, Martin G. Skjæveland, Dag Hovland, Rudolf Schlatte, Sebastian Brandt, Hallstein Lie, Ian Horrocks, Freddy Lecue
2018 Semantic Web Journal  
In particular, it exploits ontology projection techniques to enable graph-based navigation over an ontology during query construction.  ...  An important application of semantic technologies in industry has been the formalisation of information models using OWL 2 ontologies and the use of RDF for storing and exchanging application data.  ...  Indeed, note that OWL 2 axioms do not have a natural correspondence to a graph, e.g., an OWL 2 axiom of the form 'C 1 and C 2 SubClassOf: D 1 or D 2 ' can be hardly seen as a graph.  ...
