Koyal — A multi-purpose expert system — MD-CoB-CoA knowledge representation using PROLOG in J2SE

Expert systems are AI´s greatest commercial success. It is a research-oriented application area of AI. An expert system uses knowledge specific to a problem domain to provide “expert quality” performance. Predicate logic is being used for knowledge representation which is further programmed using PROLOG inference engine for deriving intelligent conclusions. The current research paper introduces a rule-based expert system that provides a medical diagnosis for determining the health problems and classification of birds and animals. The user has to have some knowledge about these topics so that he can query the system. Three knowledge bases are provided for each domain. The specialized computer language PROLOG embedded into J2SE is used to develop this system.
