Workshop on Visualization in Knowledge Engineering (VIKE)

Tuesday July 6th, 2004
Bethesda, Maryland

In conjunction with the Seventh International Protégé Conference

Knowledge engineering is often a complex area for end-user and engineer alike. This workshop explores cognitive issues in both knowledge engineering processes and tools. In the past few years, many tools have been developed to support people working with formal, complex knowledge models. These tools can be advanced visual interfaces like visualization tabs, or instance creation wizards, or simpler slot widgets that provide support in a specific area. Some of these tools include Ontoviz, Jambalaya, TGVizTab, EZ-Owl, the Instance Tree widget, and the Calendar widget.

Building on a successful session at KCAP 2003, VIKE 2004 brings together researchers and developers of these tools with practitioners who have an interest in various aspects of cognitive support and problem solving in the Protégé environment, as well as other knowledge engineering environments. Topics include, but are not limited to: This is a half-day workshop approximately 3.5 hours in duration. The workshop format is a series of presentations followed by a general discussion. Presentations may be about particular visualization or user-support tools, or (equally important) problems and suggestions for future work. We are also considering tool demonstrations and how-tos with a common ontology.

We are particularly interested in comments and presentations from end-users. If you wish to make a presentation at the workshop, you should submit a two-page summary to Neil Ernst by e-mail no later than June 1, 2004. More details will be posted at
