چکیده
A scheme for explicit ly representing and using expert knowledge of a procedural k ind is described. The scheme al lows the explicit representation of both declarative and proce dural knowledge wi th in a unified framework, yet retains all the desirable properties of expert systems such as modular i ty , ex planatory capabil i ty, and extendabil i ty. It thus bridges the gap between the procedural and declarative languages, and allows formal algorithmic knowledge to be uni formly integrated w i th heuristic declarative knowledge. A version of the scheme has been ful ly implemented and applied to the domain of automobile engine fault, diagnosis.

متن کاملA Multilevel Expert System in Medicine
This paper presents a multilevel expert system architecture for the diagnosis, prognosis and monitoring in medicine. These problems are solved with procedural programming (C language) and logical programming (CLIPS language). This double approach allowed a comparison between different methods of implementing an expert system. An important element of this project is an expert system generator, e...
متن کاملRepresenting Procedural Knowledge in Expert Systems: An Application to Process Control
The paper presents a novel expert system architecture which supports explicit representation and effective use of both declarative and procedural knowledge. These two types of expert knowledge are represented by means of produc tion rules and event-graphs respectively, and they are pro cessed by a unified inference engine. Communication between the rule level and the event-graph level is base...
متن کاملCase Study of a Method for Reengineering Procedural Systems into OO Systems
This study evaluates a method for reengineering a procedural system to an object-oriented system. Relationships between functions in the procedural system were identified using various coupling metrics. While the coupling metrics used for analysis were helpful in identifying candidate objects, domain expert analysis of the candidate objects was required. The time taken at each step in the proce...
