Solution Overview

Problem

Evaluating records, especially in medical and business contexts, remains labor-intensive and prone to human error due to low signal-to-noise ratios and complexity, making it difficult to automate accurately with traditional methods.

Innovation Solution

A method involving block manipulation and deep learning models to identify and extract relevant text blocks from medical records, processing them through an embedding layer, convolutional layer, and recurrent neural network to determine if an ICD code is supported, thereby automating the evaluation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If traditional rule-based methods are used to evaluate medical records, then the evaluation process can be automated, but the accuracy is poor due to low signal-to-noise ratio and complexity

Engineering Contradiction:
Improveautomation of record evaluationVSAvoidaccuracy of evaluation
Core Design Contradiction:
Extent of automationVSMeasurement precision

Solution Approach 1:

The patent segments the medical record into multiple blocks of text, each representing a distinct section or paragraph. This segmentation allows the system to process and evaluate each block independently, identifying relevant information while filtering out noise. The segmentation principle resolves the contradiction by enabling automated processing of individual blocks while maintaining overall evaluation accuracy through cumulative analysis of all blocks.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts relevant features and information from each text block, separating the signal (clinically relevant information) from the noise (irrelevant or redundant text). This extraction process involves identifying key entities, relationships, and patterns that are critical for accurate medical record evaluation. By taking out only the essential information, the system achieves both automation and high accuracy.

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If the entire medical record is processed to ensure comprehensive evaluation, then accuracy may be maintained, but the processing time and computational resources increase significantly

Engineering Contradiction:
Improvecomprehensiveness of evaluationVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary processing of the medical record by segmenting it into blocks and pre-identifying potentially relevant sections before full evaluation. This preliminary action includes basic text processing, block segmentation, and initial relevance assessment. By performing these actions beforehand, the system reduces the computational burden during the main evaluation phase, maintaining comprehensiveness while reducing processing time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies partial processing to each text block, focusing computational resources on the most relevant blocks while using lighter processing for less critical sections. This approach involves evaluating blocks at different levels of detail, applying more rigorous analysis only where necessary. This partial action strategy maintains overall evaluation accuracy while significantly reducing total processing time and computational resource requirements.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Embodiments are disclosed for automatically evaluating records. In the context of a method, an example embodiment includes receiving a set of text produced from a record, identifying, by block manipulation circuitry and from the set of text, one or more blocks of text that are related to a potential conclusion regarding the set of text, and extracting, by the block manipulation circuitry, the one or more blocks of text. The example method further includes concatenating, by the block manipulation circuitry, the extracted one or more blocks into a sequence of words, inputting the sequence of words into a machine learning model, and, in response to inputting the sequence of words into the machine learning model, producing, using the machine learning model, an indication of whether the potential conclusion regarding the record is supported by the sequence of words. Corresponding apparatuses and computer program products are also provided.
