Solution Overview

Problem

Conventional deep learning-based question-answering systems struggle with providing accurate responses to in-depth queries requiring sophisticated reasoning and inference, particularly in specialized documents like scientific and technical papers, due to the exponential increase in syntactic patterns and the lack of training on deep document comprehension.

Innovation Solution

A method and system using a deep-learning neural network that implements a stepwise process for sophisticated reasoning and inference, including an associative selection, rationale generation, and systematic composition process to generate response data with rationale information, enhancing the accuracy and reliability of answers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional deep learning systems use traditional question-answering methods with syntactic patterns, then they can process simple queries, but they fail to provide accurate responses to in-depth queries requiring sophisticated reasoning and inference

Engineering Contradiction:
Improveanswer accuracyVSAvoidhandling capability for in-depth queries
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system segments the question-answering process into distinct stages: query understanding, document retrieval, evidence extraction, and answer generation. This segmentation allows each component to specialize in specific tasks, enabling the system to handle complex reasoning queries while maintaining accuracy through structured processing at each stage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary reasoning module that acts as a mediator between the query and the document database. This intermediary performs sophisticated reasoning and inference operations, transforming simple query patterns into complex retrieval strategies, thereby enabling accurate responses to in-depth questions without requiring exponential syntactic patterns.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the system processes various natural languages with traditional methods, then it can handle basic queries, but the number of syntactic patterns increases exponentially causing effectiveness to decrease

Engineering Contradiction:
Improvenatural language processing capabilityVSAvoidnumber of syntactic patterns
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system changes the parameter of language understanding from syntactic pattern matching to semantic meaning representation. By transforming queries and documents into unified semantic vectors, the system can process various natural languages without requiring exponential syntactic patterns, maintaining effectiveness across diverse language inputs.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system replaces the mechanical syntactic pattern-matching system with a neural network-based semantic understanding system. This substitution eliminates the need for explicit syntactic patterns while maintaining natural language processing capability, as the neural network learns language structures implicitly through training data.

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

3Productivity

If MRC models are trained on existing datasets, then they can answer fact-based questions, but they cannot handle in-depth queries requiring deep document comprehension and reasoning

Engineering Contradiction:
Improveanswer generation speedVSAvoidreasoning capability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary action by pre-training the neural network on large corpora of specialized documents to learn domain-specific knowledge and reasoning patterns. This pre-training enables the model to understand complex relationships in documents before encountering actual queries, allowing it to handle in-depth reasoning questions while maintaining efficient answer generation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous learning by fine-tuning the pre-trained model on specific reasoning tasks and updating it with new document types and query patterns. This continuous training ensures the model maintains both fast response generation and improving reasoning capabilities over time, rather than being limited to static training data.

Inventive Principle:
Principle #20Continuity of useful action
