title: Knowledge acquisition and visualization for biomedical research.
abstract: The TreeTableWidget is a user interface component that allows instances in a knowledge-base to be sorted on the value of one or more of its attributes. Any combination of attributes can be sorted simultaneously by assigning a precedence to each sort. This results in a hierarchy of attributes such that instances can be grouped and visualized according to shared attribute values in a tree view. The resulting tree provides a mechanism to navigate and edit a large number of instances based on attribute values. The component is available as a Protégé slot-widget plug-in.
