Standard graphical representations of ontologies are flawed because the representation of non-hierarchical relations lacks appropriate support. In particular, the graphical representation of specialization and whole-part, as well as quality and dependency relationships are poorly represented. In consequence, graphical representations fail to provide the needed synoptic view of how the represented elements are interrelated.

I will show how we can use the Higraph visual formalism [1],[2] to represent domain ontologies based on BFO in a way that will provide visual representations that are both clearer and more concise. More specifically, the idea is to pursue ways to represent in a more concise and intuitive way the following aspects of BFO ontologies:

Generalization/ specialization relationships
Whole-part relationships
Qualities
Dependency relationships among entities
Occurrent and related entities

Future steps will include the exploration of using Higraph to support visual inference over content using BFO-conformant ontologies.
