Spot Presentation Priority Correction for Balanced Recommendations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems present information about spots in a biased manner when a user is in an area with many similar spots, leading to user inconvenience.
Innovation Solution
An information presentation device that detects multiple spots, corrects their presentation priority based on the number of spots per type, and selectively presents one or a predetermined number of spots using a priority correction unit and presentation control unit to prevent biased presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spots are presented based on recommended genre only, then information regarding recommended spots can be presented, but presentation becomes biased when user is in an area with many similar spots
Solution Approach 1:
The patent changes the parameter of spot selection by introducing a correction value based on the number of spots of each type in the search results. When many spots of the same type are found, a correction value is applied to adjust the selection, preventing biased presentation and improving user convenience while maintaining recommendation accuracy.
2Ease of operation
If priority correction is applied based on number of spots per type, then biased presentation is prevented, but system complexity increases
Solution Approach 1:
The patent applies local quality by implementing priority correction specifically for spot types that appear frequently in search results. Instead of uniformly complicating the entire system, the correction mechanism is selectively applied only where needed (when certain spot types dominate the results), thus achieving presentation balance without excessive system complexity.

AI summary
The mobile terminal 1 or the server device 7 functions as an information presentation device and includes a detection unit, a priority correction unit, and a presentation control unit. The detection unit detects plural spots as options for presentation. The priority correction unit corrects, based on the number of spots for each type of the plural spots, the degree of priority of the presentation of the plural spots for the each type. The presentation control unit causes, based on the corrected degree of priority, a presentation unit to present one of the plural spots.
