Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
OCR technology often introduces errors in extracting information from scanned labels due to factors like image quality, font variations, and handwriting inconsistencies, necessitating a more accurate method to assess the reliability of the extracted data.
Innovation Solution
An apparatus and method using a processor and memory to generate a confidence score for scanned labels through a confidence machine-learning model, which iteratively trains and adjusts the score based on feedback from previous iterations, ensuring accuracy.

Engineering Contradiction Analysis
1Productivity
If OCR technology is used to extract information from scanned labels, then data extraction can be performed, but errors are introduced due to image quality, font variations, and handwriting inconsistencies
Solution Approach 1:
The system implements an iterative feedback mechanism where the machine learning model generates confidence scores for extracted label data, and this feedback is used to retrain and improve the model in subsequent iterations. The confidence score feedback loop allows the system to identify and learn from extraction errors, progressively improving accuracy while maintaining high productivity through automated processing.
Solution Approach 2:
The patent replaces traditional rule-based OCR verification mechanisms with a machine learning-based confidence scoring system. Instead of relying on fixed mechanical rules for error detection, the system uses adaptive neural networks that can generalize across different label formats, fonts, and image qualities, thereby improving reliability without sacrificing extraction speed.
2Measurement precision
If a confidence machine-learning model is trained iteratively with feedback, then accuracy of confidence scores improves, but computational time and processing complexity increase
Solution Approach 1:
The system applies partial training iterations where the model is retrained only with selected feedback data rather than complete retraining from scratch. This selective retraining approach uses a subset of high-value feedback samples to improve confidence score accuracy while significantly reducing computational time compared to full model retraining.
Solution Approach 2:
The system performs preliminary confidence scoring using the existing model before full iterative retraining. This preliminary action provides immediate confidence estimates that can be used for low-stakes applications, while more intensive iterative training is reserved for cases requiring higher precision, thereby optimizing the trade-off between accuracy and time investment.
