Abstract
Making logic-based AI representations accessible to ordinary
users has been an ongoing challenge for the successful deployment
of knowledge bases. Past work to meet this objective has resulted
in a variety of ontology editing tools and task-specific
knowledge-acquisition methods. In this paper, we describe a
Web-based ontology browsing and editing system with the following
features: (a) well-organized English-like presentation of concept
descriptions and (b) use of graphs to enter concept
relationships, add/delete lists, and analogical correspondences.
No existing tool supports these features. The system is Web-based
and its user interface uses a mixture of HTML and Java. It has
undergone significant testing and evaluation in the context of a
real application.
