Heterogeneous knowledge representation using a finite automaton and first order logic: a case study in electromyography

摘要

In a certain number of situations, human cognitive functioning is difficult to represent with classical artificial intelligence structures. Such a difficulty arises in the polyneuropathy diagnosis which is based on the spatial distribution, along the nerve fibres, of lesions, together with the synthesis of several partial diagnoses. Faced with this problem while building up an expert system (NEUROP), we developed a heterogeneous knowledge representation associating a finite automaton with first order logic. A number of knowledge representation problems raised by the electrophysiological test features are examined in this study and the expert system architecture allowing such a knowledge modeling is laid out.
