Abstract
Abstract Structure-based processing includes a method of diagnosing diseases that works by arranging diseases, symptoms, and questions into a set of related disease, symptom, and question structures, such as objects or lists, in such a way that the structures can be processed to generate a dialogue with a patient. A structure-based processing system organizes medical knowledge into formal structures and then executes those structures on a structure engine to automatically select the next question. Patient responses to the questions lead to more questions and ultimately to a diagnosis. An object-oriented embodiment includes software objects utilized as active, intelligent agents where each object performs its own tasks and calls upon other objects to perform their tasks at the appropriate time to arrive at a diagnosis. Alternative symptoms, synergies, encoding of patient responses, multiple diagnostic modes, disease profiles or timelines, and the reuse of diagnostic objects enhance the processing of the system and method.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
68 words
A computerized diagnostic method, comprising: repetitively asking questions to elicit responses from a patient, the responses establishing symptoms, each established symptom contributing a weight to a disease; generating one or more synergistic weights based on the established symptoms; accumulating established symptom weights and synergistic weights for the disease; and determining whether the cumulative weight for the disease reaches or passes a threshold so as to declare a diagnosis.
Claim 2
Dependent Claim
68 words
A computerized diagnostic method, comprising: repetitively asking questions to elicit responses from a patient, the responses establishing symptoms, each established symptom contributing a weight to a disease; generating one or more synergistic weights based on the established symptoms; accumulating established symptom weights and synergistic weights for the disease; and determining whether the cumulative weight for the disease reaches or passes a threshold so as to declare a diagnosis.
Claim 3
Dependent Claim
16 words
The method defined in claim 1 , wherein generating synergistic weights includes establishing a synergistic symptom.
Claim 4
Dependent Claim
29 words
The method defined in claim 2 , wherein the synergistic symptom is based on a type of an onset or an offset of a one of the established symptoms.
Claim 5
Dependent Claim
28 words
The method defined in claim 2 , wherein the synergistic symptom is based on an onset slope or an offset slope of a one of the established symptoms.
Claim 6
Dependent Claim
28 words
The method defined in claim 2 , wherein the synergistic symptom is based on an onset trend or an offset trend of a one of the established symptoms.
Claim 7
Dependent Claim
29 words
The method defined in claim 1 , wherein a selected set of established symptoms occurring in a specified sequence over time lends an extra diagnostic weight to the disease.
Claim 8
Dependent Claim
35 words
The method defined in claim 1 , wherein one or more of the established symptoms having onset or offset characteristics matching a predefined template of symptom characteristics lends an extra diagnostic weight to the disease.
Claim 9
Dependent Claim
42 words
The method defined in claim 1 , wherein a selected set of established symptoms occurring in a specified sequence over time and having onset or offset characteristics matching a predefined template of symptom characteristics lends an extra diagnostic weight to the disease.
Claim 10
Dependent Claim
74 words
A computerized diagnostic method, comprising: repetitively asking questions over time to elicit responses from a patient, the responses establishing time varying symptoms, each established symptom contributing a weight to a disease; generating one or more synergistic weights based on the symptoms established over time; accumulating established symptom weights and synergistic weights for the disease; and determining whether the accumulated weights for the disease reach or pass a threshold so as to declare a diagnosis.
Claim 11
Dependent Claim
74 words
A computerized diagnostic method, comprising: repetitively asking questions over time to elicit responses from a patient, the responses establishing time varying symptoms, each established symptom contributing a weight to a disease; generating one or more synergistic weights based on the symptoms established over time; accumulating established symptom weights and synergistic weights for the disease; and determining whether the accumulated weights for the disease reach or pass a threshold so as to declare a diagnosis.
Claim 12
Dependent Claim
16 words
The method defined in claim 9 , wherein generating synergistic weights includes establishing a synergistic symptom.
Claim 13
Dependent Claim
19 words
The method defined in claim 9 , wherein the time varying symptoms are stored in a patient medical record.
