Strategies toward the development of an expert system for sensory evaluation testing and database management

Abstract

This paper presents design, knowledge representation, and implementation strategies aimed at the development of a knowledge system to guide and assist the sensory scientist in selection and implementation of appropriate test methods, statistical/graphical analyses, panel training, and data management. Particular emphasis is placed on how such a system can be used for panel management activities, such as screening/selecting panelists and performance monitoring. The system was designed with the capability of providing individualized graphic feedback during panel training sessions on discrimination and descriptive tasks. The prototype was built on a Macintosh computer using the Goldworks II expert system shell. Other software was interfaced and interacts with the system to provide statistical, graphical, and database support. © 1994 Psychonomic Society, Inc.
