Abstract
Abstract An applications system has been developed to assist meat graders in deciding the yield and quality grades of carcasses. The applications system comprises: (1) an input for information relating to characteristics of a carcass to be graded; (2) a program comprising a knowledge base of facts and rules relating to grading of the carcasses; (3) an inference engine for processing the input information against the facts and rules of the knowledge base to arrive at yield and quality grades for the carcass; and (4) an output for the carcass grades. An embodiment useful for the grading of beef carcasses has been illustrated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
90 words
System for grading carcasses comprising: a. means for establishing an identification for each carcass to be graded; b. input means for inputting information relating to the characteristics of said carcass to be graded and automatically correlating said information to said identification; c. a program comprising a knowledge base of facts and rules relating to the grading of carcasses; d. an inference engine for comparing said information against the facts and rules of said knowledge base; and e. means for outputting the results of said grading as related to said carcass.
Claim 2
Dependent Claim
90 words
System for grading carcasses comprising: a. means for establishing an identification for each carcass to be graded; b. input means for inputting information relating to the characteristics of said carcass to be graded and automatically correlating said information to said identification; c. a program comprising a knowledge base of facts and rules relating to the grading of carcasses; d. an inference engine for comparing said information against the facts and rules of said knowledge base; and e. means for outputting the results of said grading as related to said carcass.
Claim 3
Dependent Claim
14 words
The system of claim 1 wherein said input means is a voice recognition system.
Claim 4
Dependent Claim
37 words
The system of claim 2 wherein said voice recognition system includes a library of preprogrammed terms and expressions relating to facts of carcass values and carcass characteristics useful in determining the yield and quality grades of carcasses.
Claim 5
Dependent Claim
15 words
The system of claim 1 wherein said inference engine is data-driven and uses forward-chaining logic.
Claim 6
Independent Claim
136 words
A method for grading carcasses with the assist of a knowledge-based system, the method comprising: a. providing a program comprising a knowledge base of facts and rules relating to the grading of carcasses and an inference engine for comparing inputted information against the facts and rules of said knowledge base; b. establishing an identification for each carcass to be graded; c. inputting into the knowledge-based system information relating to the characteristics of said carcass to be graded and automatically correlating said information to the identification for that carcass; c. providing means for evoking said inference engine to compare said inputted information against the facts and rules of said knowledge base and for generating values representative of the grade of said carcass; d. providing a means for outputting the values representative of the grade of the carcass.
Claim 7
Independent Claim
136 words
A method for grading carcasses with the assist of a knowledge-based system, the method comprising: a. providing a program comprising a knowledge base of facts and rules relating to the grading of carcasses and an inference engine for comparing inputted information against the facts and rules of said knowledge base; b. establishing an identification for each carcass to be graded; c. inputting into the knowledge-based system information relating to the characteristics of said carcass to be graded and automatically correlating said information to the identification for that carcass; c. providing means for evoking said inference engine to compare said inputted information against the facts and rules of said knowledge base and for generating values representative of the grade of said carcass; d. providing a means for outputting the values representative of the grade of the carcass.
Claim 8
Dependent Claim
18 words
The method as described in claim 5 wherein said information is inputted vocally through a voice recognition system.
Claim 9
Dependent Claim
36 words
The method as described in claim 5 wherein said inputted information is allocated to a unique file for each carcass, and the input of a first predetermined unit of information initiates the creation of said file.
Claim 10
Dependent Claim
28 words
The method as described in claim 5 wherein sufficient information is inputted to allow said inference engine to generate values relating to both yield grade and quality grade.
Claim 11
Dependent Claim
13 words
The method as described in claim 5 wherein said carcasses are beef carcasses.
