Onto3DViz can provide strong support for ontological<br />

engineers in visualizing application ontologies.<br />

To address the weaknesses noted in the current<br />

version of Onto3DViz, some improvements to the tool can<br />

be made in the future. Firstly, the current graphical layout<br />

of the Onto3DViz is a tree lik e structure generated from<br />

top to bottom. It is dif ficult to exten d the rendering<br />

algorithm because it i s tightly coupled. In the future,<br />

Onto3DViz can be im plemented in a loosely coupled<br />

architecture, which enables various graphic layouts to be<br />

ported into Onto3DViz. Secondly, to address the difficulty<br />

of finding concepts in a model, a f eature that supports<br />

automatic identification of a required concept can be added<br />

to Onto3DViz. Such a search fu nction can be ad ded by<br />

providing a graphical area for the user to in put the exact<br />

text name of the concept. After th e name is accepted by<br />

Onto3DViz, it will look through the model and locate th e<br />

concept, then highlight the 3D co ordinate of the searched<br />

concept in the visualized model by adding color and<br />

lighting. These improvements will be le ft for future<br />

research.<br />
