Abstract
Abstract A rule acquisition method for expert systems receives input from the expert, one word at a time, and checks each word by determining alternative parses for the partial sentence as so far entered. Feedback is provided to the expert when a word does not conform to a required grammar, this feedback comprising a menu of legal next choices. When the sentence is completed it is translated into the form of a diagnostic rule. An expert system for troubleshooting electronic equipment is disclosed employing rules generated in the aforementioned manner.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
53 words
The method of acquiring rules for a computer-based expert system, said method comprising, serially receiving portions of a sentence input from an expert, checking said portions as they are received for their conformation to a predetermined grammar, and translating the sentence into the form of a diagnostic rule when the sentence is complete.
Claim 2
Independent Claim
53 words
The method of acquiring rules for a computer-based expert system, said method comprising, serially receiving portions of a sentence input from an expert, checking said portions as they are received for their conformation to a predetermined grammar, and translating the sentence into the form of a diagnostic rule when the sentence is complete.
Claim 3
Dependent Claim
15 words
The method according to claim 1 further including providing selection information to the expert user.
Claim 4
Dependent Claim
37 words
The method according to claim 2 wherein said selection information is given to the expert user by way of feedback in instances where the user inputs a sentence portion that does not conform to said predetermined grammar.
Claim 5
Dependent Claim
24 words
The method according to claim 3 wherein said feedback is provided in menu-fashion of possible next choices as would conform to said predetermined grammar.
Claim 6
Independent Claim
63 words
The method of acquiring rules for a computer-based expert system, said method comprising: serially receiving the words of a sentence input of an expert, checking each word as it is entered by simultaneously determining alternative parses for the partial sentence so far entered, and providing feedback information to the expert when the word entered does not match any of the current partial parses.
Claim 7
Independent Claim
63 words
The method of acquiring rules for a computer-based expert system, said method comprising: serially receiving the words of a sentence input of an expert, checking each word as it is entered by simultaneously determining alternative parses for the partial sentence so far entered, and providing feedback information to the expert when the word entered does not match any of the current partial parses.
Claim 8
Dependent Claim
30 words
The method according to claim 5 wherein said feedback information is provided in the form of a menu of possible next steps in the parses for selection by the expert.
Claim 9
Dependent Claim
22 words
The method according to claim 5 including translating the sentence into the form of a diagnostic rule when the sentence is complete.
Claim 10
Dependent Claim
23 words
