Solution Overview

Problem

Existing sentiment preference recognition models are sensitive to the order of comparison objects in sentences, leading to decreased discrimination accuracy when the positions of the objects are exchanged, and they lack intelligence and accuracy for practical applications in comparative opinion recognition.

Innovation Solution

A dual-channel sentiment preference recognition model is developed, utilizing a pre-trained language model with an original and mirror channel to generate text templates with swapped comparison objects, and a comparison module to distinguish logical relationships, enhancing robustness and accuracy by minimizing the impact of object order changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a traditional sentiment preference recognition model is used, then the model structure is simple, but the discrimination accuracy decreases when the positions of comparison objects are exchanged

Engineering Contradiction:
Improvediscrimination accuracyVSAvoidrobustness to object order changes
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies inversion by creating a mirror channel that processes the inverted version of the original text template. Specifically, when the original template is 'Product A handles better than product B', the mirror channel processes 'Product B handles worse than product A'. This allows the model to learn consistent sentiment representations regardless of object order, resolving the contradiction between discrimination accuracy and robustness to position changes.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces a new dimension by adding the mirror channel as a parallel processing path to the original channel. This dimensional expansion allows the model to simultaneously process both original and inverted text templates, enabling it to capture sentiment preferences that are invariant to object ordering while maintaining high discrimination accuracy.

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

2Measurement precision

If the model processes both original and mirrored text templates, then the sentiment preference recognition accuracy improves, but the device complexity increases

Engineering Contradiction:
Improvesentiment preference recognition accuracyVSAvoidmodel structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the original channel and mirror channel through shared parameter mechanisms. The comparison module integrates outputs from both channels and uses a shared parameter model to generate the final sentiment preference result. This merging approach allows the system to benefit from dual-channel processing while reducing overall complexity through parameter sharing and integrated output generation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The comparison module serves multiple functions: it processes outputs from both original and mirror channels, performs sentiment comparison, and generates final predictions. This multi-functional design reduces the need for separate dedicated components for each processing stage, thereby improving accuracy while controlling device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If more training data with varied object positions is used, then the model robustness improves, but the loss of time for data preparation increases

Engineering Contradiction:
Improvemodel robustnessVSAvoiddata preparation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by automatically generating mirror text templates from the original training data during the data preparation phase. Instead of manually creating varied position examples, the system programmatically generates inverted versions of each template (e.g., converting 'A is better than B' to 'B is worse than A'). This preliminary generation of diverse training examples significantly reduces data preparation time while maintaining model robustness.

Inventive Principle:
Principle #10Preliminary action
