Types of Expert System: Comparative Study

The paper describes the different classifications of expert systems.  There are mainly five types of expert systems.  They are rule based expert system, frame based expert system, fuzzy expert system, neural expert system and neuro-fuzzy expert system.  We discussed the expert systems based on their knowledge representation, inference engine, working of the system and user interface.  At the end, we provided comparative study of above five types of expert systems  based on different parameters.  We can say that choice of an expert system depends on the domain requirements.
