There is empirical evidence that the user interaction metaphors used in ontology engineering toolkits are largely inadequate and that novel interactive frameworks for human-ontology interaction are needed. Here we present a novel tool for visualizing and navigating ontologies, called KC-Viz, which exploits an innovative ontology summarization method to support a 'middleout ontology browsing' approach, where it becomes possible to navigate ontologies starting from the most information-rich nodes (i.e., key concepts). This approach is similar to map-based visualization and navigation in Geographical Information Systems, where, e.g., major cities are displayed more prominently than others, depending on the current level of granularity.
