1. Ontology Visualization Methods—A Survey

2. INTRODUCTION ONTOLOGY DEFINITION purpose of this article : The best method for an ontology

3. VISUALIZATION TECHNIQUES GROUPING 1. Indented list, 2. Node–link and tree, 3. Zoomable, 4. Space-filling, 5. Focus + context or distortion, 6. 3D Information landscapes.

4. INDENTED LIST ontology visualization systems, like kaon, Prot´eg´e offer a Windows Explorer like tree view of the ontology

5. NODE—-LINK AND TREE ontologies as a set of interconnected nodes presenting the taxonomy with a top–down or left to right layout expand and retract nodes and their subtrees, in order to adjust the detail of the information shown and avoid display clutter

6. Two Dimensional OntoViz IsaViz SpaceTree OntoTrack GoSurfer

7. OntoViz Prot´eg´e visualization plug-in using the GraphViz library to create a very 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

8. Three Dimensional Cone Tree its nodes arranged at the base of a cone and its parent at the top of the cone. That way a subtree is represented as a cone containing subcones
