Solution Overview

Problem

Current textual entailment systems are inefficient, inaccurate, and not scalable, as they primarily establish unidirectional relationships between language expressions and meanings, failing to effectively handle the multi-dimensional characteristics of natural language.

Innovation Solution

A textual entailment system that employs a neural network model using word vectors from models like Word2vec and Gensim, with a processor, entailment data organizer, hypothesis generator, and modeler to generate multi-directional relationships between text fragments, incorporating AI components for natural language processing and deep learning to derive entailment inferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If unidirectional relationship models are used for textual entailment, then the system complexity is reduced, but the accuracy and completeness of handling multi-dimensional natural language characteristics deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoidaccuracy of entailment analysis
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent transitions from unidirectional to multi-directional relationship modeling by introducing bidirectional mappings between text fragments and their semantic representations. This dimensional change allows the system to capture complex natural language characteristics while maintaining manageable system architecture through structured bidirectional transformations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If multi-directional relationships are established between language expressions and meanings, then the accuracy and completeness of textual entailment improves, but the computational complexity and processing time increases

Engineering Contradiction:
Improveaccuracy of entailment analysisVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-processing text fragments into standardized semantic representations before entailment analysis. This preliminary structuring of data enables faster multi-directional comparisons during the actual entailment checking process, reducing processing time while maintaining accuracy.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If comprehensive entailment analysis is performed to handle all natural language ambiguities, then the completeness of insights improves, but the computational resources and cost increase

Engineering Contradiction:
Improvecompleteness of insightsVSAvoidcomputational resources
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts and focuses on the most critical semantic relationships and ambiguities in text fragments rather than analyzing all possible interpretations. This selective extraction approach maintains comprehensive insight generation while significantly reducing computational resource requirements by concentrating processing power on high-impact analysis areas.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Examples of a textual entailment generation system are provided. The system obtains a query from a user and implements an artificial intelligence component to identify a premise, a word index, and a premise index associated with the query. The system may implement a first cognitive learning operation to determine a plurality of hypothesis and a hypothesis index corresponding to the premise. The system may generate a confidence index for each of the plurality of hypothesis based on a comparison of the hypothesis index with the premise index. The system may determine an entailment value, a contradiction value, and a neutral entailment value based on the confidence index for each of the plurality of hypothesis. The system may generate an entailment result relevant for resolving the query comprising the plurality of hypothesis along with the corresponding entailed output index.
