One aspect of the expert systems holds, that the metodology is, in essence a simply alternative to traditional computer programming. One approach proposes a similar procedure, as used in traditional programming, to validate expert systems. This approach is very restricted, but it's true, that there are certain universal rules, which could be used in this area. These are theories about procedural programming, which relate the organization, logic and clarity of statements, these statements could be procedural or heuristic. These rules are serving directly or indirectly the evaluation of consistency and completness within a rule base.
A big amount of discussions have to narrowly focused the problem of validation of expert systems. The global aspect was missing. If we considering a more global approach to the validation, the whole process of validation consists of the following three steps:
Keywords:
checking, appropriateness, consistency, completness of the rule base, reduntant, conflicting, subsumed rules, circular rules, unachievableness, completness, unreferenced values, illegal values, uncertainity, performance of ES
