A proposed diagrammatic logic for ontology specification and visualization
Ian Oliver, John Howse, Gem Stapleton, Esko Nuutlia, Seppo Törmä · 2009
We propose a diagrammatic logic that is suitable for specifying ontologies. We provide a specification of a simple ontology and include examples to show how to place constraints on ontology specifications and define queries. The framework also allows the depiction of instances, multiple ontologies to be related, and reasoning about ontologies. 1.
