Design and Implementation of a Knowledge-Based Expert System Shell

Abstract

For the purpose of shortening the development cycle of expert system, an approach of developing a knowledge-based expert system shell is proposed. A friendly human machine interaction expert system shell is developed by the hybrid programming technology based on C Language Integrated Production System (CLIPS) and C++. And an efficient knowledge management mechanism is realized by SQL Server database. The main functional modules of this expert system shell include inference engine, knowledge base management system, knowledge base, fact base, interpreter and human machine interface. The correction of this expert system shell was validated through a case study that an expert system built by the expert system shell successfully aided diagnosed and treated an 11 years old adolescent idiopathic scoliosis patient. The results implied that the expert system shell proposed can build an expert system rapidly and effectively.
