An integrated approach for evaluating the visualization of intensional and extensional levels of ontologies

Abstract

Visualization of ontologies is based on effective graphical representations and interaction techniques that support users tasks related to different entities and aspects. Ontologies can be very large and complex due to the levels of classes hierarchy as well as the attributes. In this work we present a study involving the investigation and proposition of guidelines to help the design and evaluation of visualization techniques for both the intensional and extensional levels of ontologies.
