The purpose of this study was to understand the cognitive processes and procedures employed by an expert and a novice engineer in a realistic radio frequency (RF) systems engineering design challenge by using verbal protocol analysis (VPA). The engineering design challenge encompassed engineering, political, and social constraints. The audio data were then transcribed, segmented, and coded for ...

This paper introduces a novel architecture for expert systems performing diagnostic problem-solving. The architecture is called \categorization-based" because problems are solved by relating them to relevant categories of known cases using deep knowledge about the application domain. The eeectiveness of the architecture has been validated by an implemented expert system called CHATKB, which doe...

A soft expert system is defined to be one that is qualitatively fuzzy. In this paper, we present such a system known as “KASER” which stands for ‘Knowledge Amplification by Structural Expert Randomization”. KASER facilitates reasoning using domain specific expert and commonsense knowledge. It accomplishes this through object-classed predicates and an associated novel inference engine. It addres...

The quality of a software system highly depends on its architectural design. High quality software systems typically apply expert design experience which has been captured as design patterns. As demonstrated solutions to recurring problems, design patterns help to reuse expert experience in software system design. They have been extensively applied in industry. Mining the instances of design pa...
