ABSTRACT:
The present invention includes an approach to improving run-time performance of rule-based systems. A series of testing element nodes making up a testing element is adapted to a match discrimination network utilized in an expert system to permit scanning of incoming data prior to traversing large segments of the nodes in the match discrimination network. By placing a series of testing element nodes into a traditional match discrimination network, interaction among data objects and nodes of the match discrimination network are minimized.
