Summary

In this paper, the authors draw a conclusion that there are no visualization tools available that can combine 2D and 3D dimensional views. They present their own ontology visualization approach where a reasoner is used to transform an ontology to the graph structure. This graph structure can be visualized with 5 different geometrical representations, with different level of depth and with a subset of properties of the user choice.

Key points

The authors use a reasoner services to generate a taxonomy and infer another relationship between concepts.

(1)Representations of Views Based on Different Relations

The authors elaborate the idea of Traversal View for their visualization and visualize a graph structure that represents part of ontology. They only provide the global level of traversal depth, namely all the properties will be traversed with the same depth.

(2)Representations of Views Based on Different Geometry

The authors implemented two Euclidean views: Sphere and Disk. Also they implemented the Stereographic views.

Sphere visualization: the root concept is placed in the center of the visualization window. The sub/super classes and related concepts surround the root concept and are evenly spaced on the imaginary sphere surface

The Klein Model, and the Poincare Disk model: based on the hyperbolic geometry and realize the so called “focus + context” techniques.

Stereographic views: the graph structure is laid out at the surface of a sphere.
