Opinion Direction Estimation for Conflicting Content Retrieval

Solution Overview

Problem

Conventional information distribution systems fail to easily provide users with content indicating conflicting opinions on a selected theme, limiting their ability to view diverse perspectives.

Innovation Solution

An information processing apparatus that estimates the direction of an opinion in a content, searches for and provides conflicting content when a user performs a flipping operation, utilizing text mining and sentiment analysis to identify and present opposing viewpoints.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If personalized content filtering is implemented to provide relevant news articles, then user satisfaction with relevant content is improved, but ability to view diverse opinions deteriorates

Engineering Contradiction:

Improveuser satisfaction with relevant contentVSAvoidability to view diverse opinions

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system pre-calculates and stores opposite keywords and conflicting content identifiers in advance for each news article. When a user views a news article, the system immediately retrieves and presents the pre-prepared conflicting content without requiring additional search or filtering operations, thus maintaining both personalization and diversity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary mechanism that automatically identifies and presents conflicting viewpoints. The opinion direction estimation unit and conflicting content search unit act as intermediaries between the user's personalized content request and the diverse opinion requirement, balancing both needs through automated mediation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If content filtering based on user selection is applied, then relevance of provided content is improved, but accessibility to conflicting opinions deteriorates

Engineering Contradiction:

Improverelevance of provided contentVSAvoidaccessibility to conflicting opinions

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system pre-calculates and stores opposite keywords and conflicting content identifiers in advance for each news article. When a user views a news article, the system immediately retrieves and presents the pre-prepared conflicting content without requiring additional search or filtering operations, thus maintaining both personalization and diversity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to users by presenting conflicting opinions alongside personalized content. The opinion direction estimation unit analyzes the user's selected content and provides feedback in the form of contrasting viewpoints, enabling users to understand different perspectives on the same topic.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If automated opinion direction estimation is implemented, then ability to identify conflicting content is improved, but processing time deteriorates

Engineering Contradiction:

Improveability to identify conflicting contentVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-calculates and stores opposite keywords and conflicting content identifiers in advance for each news article. When a user views a news article, the system immediately retrieves and presents the pre-prepared conflicting content without requiring additional search or filtering operations, thus maintaining both personalization and diversity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the parameter of opinion direction from a continuous spectrum to discrete categories (positive, negative, neutral). This parameter change enables faster processing by the opinion direction estimation unit, as it can quickly classify content into predefined categories rather than analyzing nuanced opinion gradients.

Inventive Principle:

Principle #35Parameter changes

AI summary

An information processing apparatus according to the present application includes an estimation unit that estimates a direction of an opinion that is expressed in a predetermined content, a search unit that searches for a conflicting content that indicates a conflicting opinion that conflicts with the direction of the opinion that is estimated by the estimation unit, and a providing unit that provides the conflicting content when predetermined operation (for example, operation of flipping the predetermined content) is performed on the predetermined content.
