Rules Verification and Validation
Antoni Ligęza, Grzegorz Jacek Nalepa · IGI Global eBooks · 2009
In this chapter an introduction to verification of rules is presented. Logical models of rules, knowledge representation languages and inference rules are introduced in brief. Required characteristics of rulebased systems are analyzed and issues of formal verification techniques for rules are presented in details. The aim is to show how the quality of rules can be improved or kept at a relatively high level, even in environments with numerous active rules. This involves verification methods for rules discussing the expressive power issues of different rule representation logical languages. Moreover, verification checks for rules incorporating consistency, redundancy, completeness and minimal form are presented.
