– Human support – ontologies not just read by machines! – Pictures & diagrams support understanding (hopefully!)
– OntoViz, OWLViz, TGViz, ezOWL – IsaViz: visual RDF editor – Many many graph-like visualization tools!
– Jambalaya = SHriMP + Protégé & Protégé-OWL glue – What is SHriMP?

– Where should a visualization be? – When would the user want to see it? – How is the data best represented in the viz?
– How can we provide a useful visualization at the moment a user needs it?
– Viz should be available from other tabs – Viz should immediately answer a specific question – Viz should not take too long to generate

– Good scalability test-bed – OWL client-server database project – Over 1 million rows in table
– Progress dialog with cancel – Confirmation if potentially too much data – Nested graph approach helps (like a tree wiget)
– Ex. Don’t show me any individuals/instances

– Problem! What should they be? Each usage of Protégé is different! Multiple ‘meta-model’ variations.
– Inspiration: next presentation, Selective Ontology Viewer – Automatic working set and Degree-of-Interest

– Inspiration: IsaViz Graph Stylesheets (GSS)
– One approach: CVF (Neil Ernst Master’s Thesis) – Inspiration: Large Model Visualization from this morning
