Fuzzy Knowledge Base Representation in the Form of Metagraph and Fuzzy Inference Based On It

Abstract

The paper describes an approach for Mamdani fuzzy knowledge base representation in the form of a metagraph and its further usage. This approach includes the method for construction of the metagraph, that biunique corresponds to the fuzzy knowledge base, methods for the metagraph preparation, that helps to increase the fuzzy inference efficiency and to determine some contradictions. The fuzzy inference based on the metagraph is proposed. The examples of the graphical representation of the fuzzy knowledge base in the form of the metagraph are given.
