Method for associating text in automatic diagnostic system to produce recommended actions automatically
First Claim
1. A method of automatically determining a recommended action in response to diagnosis of a malfunction in equipment, comprising the steps of:
- (a) defining a correspondence between each possible diagnosis and a recommended action set including at least one action(b) producing a diagnosis, having recommended actions associated therewith, in dependence upon a first set of evidence of conditions currently existing in the equipment; and
(c) selecting, using a computerized process, one of the recommended actions in the recommended action set corresponding to the diagnosis produced in step (b) in dependence upon a second set of evidence of conditions, different from the first set of evidence, both required and assumed evidence being includable in the second set of evidence, using a computerized process including the steps of(c1) comparing data representing actual conditions associated with the equipment being diagnosed to the second set of evidence; and
(c2) determining an appropriate action when the data indicates that the conditions corresponding to any required evidence exist and any assumed evidence is uncontradicted by the data.

Abstract
A method for automatically generating recommended actions in response to a diagnosis uses a list ordered by impact of the actions. The list is evaluated using required evidence which must be supported by data and assumed evidence which must not be contradicted by the data. The method is applied to the diagnosis of malfunctions in equipment by an expert system rulebase. A correspondence is defined between text modules including the recommended actions and each of the schemata in the rulebase which produce a diagnosis. After a diagnosis is evaluated as true, the corresponding text modules are evaluated to produce a recommended action. The text modules can also be used for documentation of the rulebase.

5. A method of associating text with schemata in a rulebase of an expert system for a evaluating data using the schemata in the rulebase, comprising the steps of:
-
(a) storing the selection criteria, independent of the schemata in the rulebase, for selecting text modules and a correspondence between the schemata in the rulebase and the text modules, (b) diagnosing existing conditions represented by the data in dependence upon the schemata in the rulebase; (c) automatically outputting at least one of the text modules in dependence upon the existing conditions diagnosed in step (b) and the correspondence and selection criteria stored in step (a); and (d) selectively outputting any of the text modules when said diagnosing in step (b) is not being performed. - View Dependent Claims (6, 7, 8)

9. A method of associating text with schemata in a rulebase of an expert system for a evaluating data using the schemata in the rulebase, comprising the steps of:
-
(a) storing selection criteria, independent of the schemata in the rulebase, for selecting text modules and a correspondence between the schemata in the rulebase and the text modules, including a header in each of the text modules to identify a corresponding schemata; (b) diagnosing existing conditions represented by the data in dependence upon the schemata in the rulebase; (c) associating an evidence set with each of the text modules; and (d) automatically outputting, when the data is being evaluated, at least one of the text modules when the header stored therein identifies the corresponding schemata having been evaluated as true and the evidence set associated therewith is evaluated as true for the data being evaluated. - View Dependent Claims (10, 11, 12, 13, 14)
