Solution Overview

Problem

Existing user interface systems for recommending services do not allow users to assess the reliability of profile information used to provide recommendations, leading to uncertainty about the accuracy of the recommended information.

Innovation Solution

An information providing apparatus that accumulates user profile information, performs searches based on current profile data, and calculates reliability, allowing the output of search results in a determined mode that reflects the reliability of the profile information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If profile information is accumulated and used for recommendations, then recommendation accuracy is improved, but user awareness of profile reliability is insufficient

Engineering Contradiction:

Improveprofile information reliabilityVSAvoiduser awareness of reliability

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system calculates reliability information based on accumulated profile information and feeds back to the user through the output mode. This feedback mechanism allows users to understand the reliability of their profile information without requiring complex explanations, resolving the contradiction between improving reliability and maintaining user awareness.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system changes the output mode of search results based on the reliability parameter of profile information. When reliability is high, the output mode reflects confidence; when reliability is low, it indicates uncertainty. This parameter-driven approach makes reliability transparent to users while maintaining recommendation functionality.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If recommend information is displayed without reliability indicators, then user interface simplicity is maintained, but user understanding of recommendation basis is insufficient

Engineering Contradiction:

Improveuser interface simplicityVSAvoiduser understanding of recommendation basis

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

Instead of adding complex reliability indicators to the interface, the system inverts the approach by using the output mode itself to convey reliability information. The output mode becomes the carrier of reliability data, maintaining interface simplicity while providing necessary information about recommendation basis.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The output mode serves multiple functions: it displays search results and simultaneously communicates reliability information. This multi-functionality allows the system to maintain simple interface design while providing comprehensive user feedback about profile information reliability and recommendation accuracy.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

There is provided an information providing apparatus including: an accumulating section sequentially accumulating profile information of a user, which is generated by newly collecting user-relevant information including an action history of the user; an acquiring section acquiring a search result in a case where information search according to a request of the user is performed by using current profile information in the accumulated profile information; and a control section determining an output mode on the basis of the accumulated profile information to perform control such that the acquired search result is output in the determined output mode.
