Integrating a knowledge-based meat-grading system with a voice-input device.

Abstract The U.S. livestock and meat industries depend heavily on the USDA to provide the rating of their meat for marketing. Since the carcass-beef grading system was put in place in 1927, carcasses have been graded by human graders. To achieve better consistency and equity, a knowledge-based expert system for assisting graders to grade carcass beef has been developed. This paper presents the development of the knowledge-based expert system and discusses how the expert system was integrated with a voice-recognition subsystem that provides the characteristics of the carcasses to the expert system.
