Abstract: Most expert systems apply the rule-based approach as knowledge representation formalism. The paper presents another representation means, namely a generalization of Petri nets, and discusses how the rule-based approach can be viewed through this formalism with all the ensuing consequences.
Keywords: generalized net; expert system.
