GLOW is a visualization for OWL ontologies, based on Hierarchical Edge Bundles.

In the past decade, a lot of effort has been put into the visual representation of ontologies. However, present visualization strategies are not equipped to handle complex ontologies, leading to visual clutter and ineffecient use of space. Many ontologies contain hierarchical concept structures, such as those formed by `subclass-of' relations, as well as separate adjacency relations. In this paper, we propose GLOW, a method for ontology visualization based on Hierarchical Edge Bundles. Hierarchical Edge Bundles is a new visually attractive technique for displaying adjacency relations in hierarchical data. The displayed relations can be selected from an ontology using a set of common configurations, allowing for discovery of information. We have developed a visualization library based on OWL API, as well as a plug-in for Protégé, a well-known ontology editor.
