July 23, 2006The CHISEL Group, University of Victoria2 Introduction Who am I? –Computer Science and Physics bachelor’s degree from University of Victoria, BC, Canada –10 months of part time work on Shrimp and Jambalaya –Involved with the NCI project – migrating to Protégé-OWL –Part of the National Centre for Biomedical Ontology (NCBO)National Centre for Biomedical Ontology Introduction Visualizations Installation Features Quick Views Tools Options New Features Future Work Questions Advanced Features OWL Links

July 23, 2006The CHISEL Group, University of Victoria3 Visualizations and Jambalaya Why are Visualizations important? –Ontologies can be extremely large and complex – too difficult to navigate using just trees and lists –Visualizations can help users understand ontologies by showing overviews and identifying hub concepts Other visualization approaches: –OntoViz, OWLViz, TGViz, ezOWL –IsaViz: visual RDF editor –Many graph-like visualization tools! What is Jambalaya? –Protégé Plug-in built on top of SHriMP –What is SHriMP? Nested or flat graphs Originally for software understanding – analyzing source code Also comes as a plugin for Eclipse (Creole) Smooth animated zooming & layouts Embedded AWT/Swing widgets (e.g. Protégé forms) Introduction Visualizations Installation Features Quick Views Tools Options New Features Future Work Questions Advanced Features OWL Links
