Abstract

Rule groups with preconditions, postconditions, and termination conditions were added to the ADVISE Meta-Expert System. Multiple, varying goals are also an attribute of the new rule groups. By treating the data collection process as separating from the rule inference engine, techniques for enhanced data acquisition were developed using semantic networks to describe relations among variables and to restructure value sets for variables dynamically. Having thus extended the ADVISE tools, an automated key to alfalfa field pest identification was selected as a test application and found to be particularly well suited by the new features. A need for disjunctive (“OR”) constructs in the right hand side of rules is discussed, and directions for future applications are given.
