OntoViBe 2: Advancing the Ontology Visualization Benchmark

A variety of ontology visualizations have been presented in the last couple of years. The features of these visualizations often need to be tested during their development or for evaluation purposes. However, in particular for the testing of special concepts and concept combinations, it can be difficult to find suitable ontologies. We have developed OntoViBe, an ontology covering a wide variety of OWL language constructs for the purpose of testing ontology visualizations. This paper presents OntoViBe 2, which extends the first version by annotations, individuals, anonymous classes, and a module for testing different combinations of cardinality constraints, among others. We describe the design principles underlying OntoViBe 2 and present the supported features in a coverage matrix. Finally, we load OntoViBe 2 with ontology visualization tools and point to some noteworthy aspects of the respective visualizations that become apparent and demonstrate how OntoViBe can be used for testing ontology visualizations.
