Solution Overview

Problem

Generative AI models often generate inaccurate or incomplete structured documents due to vague or underspecified prompts, leading to clinical and legal risks, inconsistency, and difficulty in tracing data incorporation, with prompt engineering requiring significant user effort and expertise.

Innovation Solution

A method involving automated prompt tuning that compares AI-generated intermediary structured documents with curated documents, generates a scoring, and refines prompts using a second generative AI model to improve accuracy and consistency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standardized pre-validated prompt templates are used, then reliability is improved, but adaptability deteriorates

Engineering Contradiction:
Improvedocument accuracyVSAvoidtemplate flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts prompt templates based on performance feedback. The automated prompt tuning process modifies prompt parameters and structure in response to evaluation results, transforming static templates into adaptive systems that evolve to improve document accuracy while maintaining flexibility for different document types and requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback loop where generated documents are evaluated against ground truth data, and the evaluation results are used to automatically refine prompt templates. This continuous feedback mechanism enables the system to learn from errors and improve reliability over time without sacrificing adaptability, as the feedback is applied to the general prompt structure rather than hardcoding specific responses

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If manual prompt engineering is performed, then manufacturing precision is improved, but loss of time increases

Engineering Contradiction:
Improveprompt specification accuracyVSAvoidprompt development time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs self-service by automatically generating and optimizing prompt templates without requiring manual prompt engineering. The automated prompt tuning process uses AI models to generate prompts, evaluate their performance, and iteratively improve them based on feedback, eliminating the need for specialized prompt engineering expertise and significantly reducing development time while maintaining or improving precision

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces the manual mechanical process of prompt engineering with an automated AI-driven system. Instead of relying on human experts to craft and refine prompts manually, the system uses machine learning models to automatically generate, evaluate, and optimize prompts, substituting human cognitive work with computational processes that are faster and more consistent

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If vague prompts are used, then ease of operation is improved, but manufacturing precision deteriorates

Engineering Contradiction:
Improveprompt simplicityVSAvoiddocument completeness
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system performs preliminary action by pre-processing input data and automatically structuring it before generating the document. The automated prompt tuning process prepares comprehensive context and structured data in advance, allowing the use of simpler, more natural language prompts while ensuring all necessary information is included and properly formatted, thus maintaining document completeness without requiring complex detailed prompts

Inventive Principle:
Principle #10Preliminary action

AI summary

A method, computer program product, and computing system for processing an intermediary structured document generated by a first generative artificial intelligence (AI) model using a plurality of predefined prompts. The intermediary structured document is compared with a curated structured document. A scoring of the intermediary structured document is generated based upon, at least in part, the comparing of the intermediary structured document with a curated structured document. One or more revisions for the plurality of predefined prompts are generated by processing the scoring of the intermediary structured document using a second generative AI model.
