INDENTED LIST

ontology visualization systems, like kaon , Prot´eg´e

offer a Windows Explorer liketree view of the ontology

NODE—-LINK AND TREE

ontologies as a set of interconnected nodespresenting the taxonomy with a top–down or left to right layoutexpand and retract nodes and their subtrees, in order to adjust the detail ofthe information shown and avoid display clutter

OntoViz

Prot´eg´e visualizationplug-in using the GraphViz library to create avery simple 2D graph visualization method. The ontology is presented as a 2D graph

(Figure 2 ) with the capability for each , class to present apart from the

, name its properties,and inheritance and role relations

Three Dimensional

Cone Treeits nodes arranged at the base of a cone and its parent at the top of the cone. Thatway a subtree is represented as a cone containing subcones
