From: Dick Jackson Subject: REQUEST: GUIs for rule base coverage? Date: 11 May 92 14:14:48 +0600 Message-ID: <1992May11.141449.1162@ciit85.ciit.nrc.ca> Organization: National Research Council Canada Gentle readers, I would like to ask if any of you are involved in, or have any references to work in a certain area of interface design and visualization, as applied to expert system building tools. A current project of mine involves a system to allow a user (a domain expert) to compose a rule base for use by other end-users. A rule is made up of a set of conditions and a set of actions, all built from a fairly constrained set of condition and action types. One of our aims is to encourage the user to provide complete coverage of the "condition-space", that is, for any possible combination of conditions, there would exist at least one rule whose conditions would be satisfied. I feel that, as the user adds rules, a display giving graphical feedback as to the ongoing coverage of the multi-dimensional "condition-space" is appropriate, and we have implemented this with some degree of success. In a sense, this is an application of mapping a highly-dimensional space to a much smaller one which is comprehensible and useful to the user. Without going into excessive detail, thereby leaving out a lot of the thorny issues that lurk in this sort of thing, I'd appreciate hearing from anyone who has worked on a similar sort of interface, or hearing OF any existing work, in papers, books, etc. Thanks in advance, -Dick Dick Jackson Institute for Biodiagnostics National Research Council Canada Winnipeg, Manitoba jackson@qm.ibd.nrc.ca Any opinions: Mine alone!
