ABSTRACT:
An improved expert system is disclosed wherein rules are organized into domains and subdomains, and objects are passed to rules to be operated upon. Prior to operating upon any object, the domain determines if the object is of the type which is to be operated upon by rules within the rule domain. If not, the rules are not applied to the object.
