Gift Recommendation System Using Recipient Evaluation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online gift systems lack the ability to determine whether the recipient is pleased with the gift, as personal attributes do not guarantee shared preferences among individuals with similar information.
Innovation Solution
A system that includes an evaluation interface for recipients to rate gifts, storing these evaluations, and using this information to estimate and present preferred gift candidates to subsequent givers, based on past evaluations, prioritizing high-rated items and adjusting priorities based on giver differences and evaluation thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If personal attribute information (name, address, interest, family structure) is used to select gift items, then gift selection can be automated and efficient, but the reliability of gift selection decreases because persons with the same attributes are not necessarily pleased at the same gift
Solution Approach 1:
The system implements a feedback mechanism where recipients evaluate received gifts through an evaluation interface. These evaluations are stored and used to improve future gift recommendations. The feedback loop transforms subjective recipient preferences into objective data that enhances selection accuracy without reducing efficiency.
Solution Approach 2:
The system performs preliminary actions by collecting and storing evaluation information from recipients in advance. This pre-collected data is then used to estimate candidate items for future gifts, allowing the system to make reliable recommendations before the actual gift selection occurs.
2Reliability
If evaluation interfaces and data collection systems are implemented, then gift selection reliability improves, but device complexity and operational burden increase
Solution Approach 1:
The evaluation interface is designed to be self-service oriented, where recipients automatically provide feedback without requiring manual data collection from givers. The system automates the entire process of evaluation collection, storage, and utilization, reducing operational burden while maintaining high reliability.
3Measurement precision
If evaluation information is collected and stored for all recipients, then gift recommendation accuracy improves, but information storage requirements and processing time increase
Solution Approach 1:
The estimation unit extracts only the necessary evaluation information relevant to gift selection from the stored data. Rather than processing all collected information, the system selectively extracts and utilizes evaluation data that directly contributes to estimating candidate items, reducing processing overhead while maintaining accuracy.
Data Source
AI summary
An information provision device according to one embodiment includes an evaluation request unit, an evaluation registration unit, an estimation unit and a presentation unit. The evaluation request unit transmits an evaluation interface for a recipient to evaluate a given gift given to the recipient to a recipient terminal. The evaluation registration unit stores an entered evaluation as evaluation information into an evaluation storage unit. When a next giver gives a next gift to the recipient through a giver terminal, the estimation unit estimates candidate items for the next gift at least from given gifts based on evaluations indicated by the evaluation information corresponding to the recipient. The presentation unit transmits candidate information indicating the estimated candidate items to the giver terminal and thereby presents the candidate items to the next giver.
