Multi-Agent NLP Framework for Accurate Unstructured Data Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Natural Language Processing (NLP) techniques struggle with unstructured documents due to their complexity, variability, and context-dependent nature, leading to incomplete or inaccurate data extraction, particularly when dealing with nuanced information that is not explicitly structured or categorized.
Innovation Solution
A multi-agent framework comprising a summarizer, assessor, and verifier agent collaboratively process unstructured text to enhance extraction accuracy, where the summarizer distills content, the assessor identifies relevant data points, and the verifier validates the correctness of the extracted information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional NLP techniques are used on unstructured documents, then processing speed is maintained, but data extraction accuracy deteriorates due to inability to handle complexity and context
Solution Approach 1:
The patent segments the NLP processing task into three distinct agent roles: summarizer agent that creates condensed representations of unstructured text, assessor agent that identifies potential target information, and verifier agent that validates extraction accuracy. This segmentation allows each agent to specialize in specific subtasks, improving overall extraction accuracy while managing complexity through modular design.
Solution Approach 2:
The patent introduces a summarizer agent as an intermediary component that transforms unstructured text into a summarized format before assessment and verification. This intermediary step creates a more manageable representation that preserves contextual information while reducing complexity, enabling subsequent agents to work more effectively on extraction and validation.
2Measurement precision
If single-agent NLP systems are used, then system simplicity is maintained, but extraction accuracy deteriorates due to inability to perform contextual validation
Solution Approach 1:
The patent implements preliminary summarization of unstructured text before the assessment and verification stages. The summarizer agent creates a condensed representation that preserves essential contextual information, allowing subsequent agents to work with pre-processed data that requires less intensive processing time while maintaining extraction accuracy.
Solution Approach 2:
The patent employs a multi-agent verification process where the verifier agent performs targeted validation on specific extracted information rather than complete re-analysis. This partial verification approach focuses computational resources on critical validation points, achieving high accuracy without requiring excessive processing time for redundant checks.
3Measurement precision
If manual NLP analysis is performed, then extraction accuracy can be improved through human judgment, but productivity deteriorates due to significant manual effort required
Solution Approach 1:
The patent implements a self-verification mechanism where the verifier agent autonomously validates extracted information against the original unstructured text and contextual cues. This automated self-service validation reduces the need for manual verification while maintaining high accuracy standards, significantly improving processing efficiency compared to fully manual analysis.
Solution Approach 2:
The patent incorporates feedback loops where the verifier agent's validation results can trigger re-assessment by the assessor agent or refinement by the summarizer agent. This iterative feedback process automatically corrects extraction errors and refines accuracy without requiring manual intervention, maintaining high precision while preserving automated processing efficiency.

AI summary
The disclosure relates to a multi-agent framework that includes a plurality of language model (LM) agents that each perform a respective Natural Language Processing (NLP) task to analyze content having natural language text. An LM agent may execute a language model to perform its respective NLP task. For example, to identify target information within content, a first LM agent in the multi-agent framework may generate a summary of the content along with the target information, a second LM agent may extract, independently from the first LM agent, the target information and output reasoning that explains why the target information was extracted, and a third LM agent may verify that the target information was correctly identified based on the output of the first and second LM agents.
