Solution Overview

Problem

Existing technologies lack the ability to accurately verify the truthfulness of assertions in human language content by correlating them with corroborating or contradictory evidence from multiple sources.

Innovation Solution

A method and system that process human language content to identify assertions, query multiple content sources for relevant corroborating or contradictory information, and present the original content with indications of the verification results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple content sources are queried to verify assertions, then the accuracy of truthfulness verification is improved, but the system complexity and processing time increase

Engineering Contradiction:

Improveaccuracy of truthfulness verificationVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The verification system is segmented into specialized modules: assertion identification module that extracts claims from content, content source querying module that searches multiple sources, correlation module that matches evidence to assertions, and credibility scoring module that evaluates source reliability. This segmentation allows each component to focus on a specific task, improving overall verification accuracy while managing system complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary components including a knowledge graph that structures relationships between assertions and evidence, and a credibility scoring system that mediates between multiple content sources. These intermediaries organize and evaluate information from diverse sources, enabling accurate truthfulness verification without requiring direct complex interactions between all system components.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If multiple content sources are queried to verify assertions, then the accuracy of truthfulness verification is improved, but the processing time increases

Engineering Contradiction:

Improveaccuracy of truthfulness verificationVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-establishing credibility scores for content sources based on their historical reliability, and by maintaining a knowledge graph of known relationships and facts. When verifying assertions, the system queries only relevant sources identified through the knowledge graph, rather than searching all possible sources, thus reducing processing time while maintaining verification accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies partial action by querying a selective subset of content sources rather than all available sources. The system identifies the minimum necessary number of sources based on assertion importance and available evidence, performing verification with sufficient rather than exhaustive searching, thereby reducing processing time while maintaining adequate verification accuracy.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If assertions are identified and verified against multiple content sources, then the reliability of information presentation is improved, but the device complexity increases

Engineering Contradiction:

Improvereliability of information presentationVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The verification apparatus is divided into distinct functional modules: an assertion identification module that extracts claims from content, a content source querying module that searches multiple sources, a correlation module that matches evidence to assertions, and a credibility scoring module that evaluates source reliability. This segmentation enables reliable information presentation through specialized processing while managing device complexity through modular architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements multi-functional components that handle various verification tasks. The knowledge graph serves multiple purposes: storing factual relationships, guiding source selection, and structuring verification results. The credibility scoring system universally evaluates different types of content sources (news articles, academic papers, websites) using a unified framework, reducing the need for source-specific processing logic and managing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A processing system may obtain first content including human language via a computing network. The processing system may next identify an assertion in the first content and identify one or more content sources containing second content relating to the assertion. The processing system may then determine whether the second content relating to the assertion corroborates or contradicts the assertion, and may present the first content with an indication of whether the second content corroborates or contradicts the assertion.
