Outline

This paper presents OntView, a new ontology visualization tool, to solve the visualization problem of ontology. Pointing out that existing ontology editors and visualization tools have difficulty in expressing the structure of large-scale ontologies meaningfully and concisely, OntView focuses on intuitively visualizing ontology concepts and formal definitions through a user-friendly interface. It follows the "What you see is what you meant" paradigm that shows inferred knowledge by utilizing DL inferrer, and provides the general concept inclusion (GCI) visualization function that existing tools do not have. In addition, to prevent information overload, it provides functions such as generating ontology summaries by evaluating importance based on various algorithms, focusing on TBox elements between two classes, and hiding and showing specific branches. OntView is open source.

Takeaways, Limitations

Takeaways:
Contributes to improving ontology understanding through a user-friendly interface
Provides GCI visualization capabilities that are not available in existing tools
Provides various visualization options to prevent information overload (generate summaries, focus on specific parts, hide/show branches)
Expanding Ontology Research and Utilization through Open Source Disclosure
Limitations:
This paper lacks a performance evaluation of OntView or a comparative analysis with other tools.
Further research is needed on the applicability and extensibility to various types of ontologies.
An objective evaluation of the intuitiveness and usability of the user interface is needed.
