Visualizing the Evolution of Ontologies: A Dynamic Graph Perspective.
Michael Burch, Steffen Lohmann · 2015
Ontologies can be represented as graphs, since they essentially comprise a set of interconnected concepts describing a certain field of knowledge. Consequently, ontologies are often visualized as graphs, using different visual notations and common graph drawing techniques. The visualization of static graphs has been researched a lot, but when it comes to time-varying graphs, researchers face much more challenges in order to design useful, readable, and intuitive visualizations. If we have to deal with dynamic, i.e., evolving and time-dependent ontologies, we have to adapt existing visualization techniques to this challenging problem or develop new ones. In this position paper, we take a look at the visual representation of time-varying ontologies, and provide a discussion from a dynamic graph visualization perspective.
