Abstract

Current trends indicate that the prevalence of ontologies will continue to increase within many domains. They are already commonly used to define controlled medical terminologies and form the backbone of the Semantic Web initiative. Very few tools that support versioning of ontologies are currently available, and those that provide difference detection and visualization are particularly lacking. We have implemented a tool called PROMPT-Viz that provides advanced visualizations using treemaps to help understand the location, impact, type and extent of changes that have occurred between versions on an ontology. PROMPT-Viz runs as a plug-in for the popular ProtCgC knowledge engineering environment and as such should be applicable to a large number of ontology developers.
