ARTIFICIAL INTELLIGENCE REVIEW, vol.19, no.4, pp.263-283, 2003 (SCI-Expanded)
Following a short survey of input data types on which to construct interactive visual user interfaces, we report on a new and recent implementation taking concept hierarchies as input data. The visual user interfaces express domain ontologies which are based on these concept hierarchies. We detail a web-based implementation, and show examples of usage. An appendix surveys related systems, many of them commercial.
