Adaptive Search Result Display for User Preference Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in finding desired search targets within a list of search results due to discontinuous arrangement order, leading to increased time and effort in selecting relevant information.
Innovation Solution
An information processing device that compares attribute values of search targets and adjusts their display modes based on user preferences, making more advantageous options more visually prominent and less advantageous options less prominent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If search results are displayed according to a fixed arrangement order (e.g., popularity, price, dictionary order), then the search system can efficiently organize and present information, but users cannot easily find desired search targets when the arrangement order is discontinuous or does not match user preferences
Solution Approach 1:
The patent applies dynamics by making the display order of search results adaptive rather than fixed. The system dynamically adjusts the arrangement order based on user selection behavior - when a user selects a search target, the system learns from this action and reorders subsequent displays to prioritize similar or related targets, creating a responsive interface that evolves with user needs
Solution Approach 2:
The patent implements feedback mechanisms where user selections are captured and used to modify the search result arrangement. The system monitors which search targets users select and uses this feedback information to adjust the display order, ensuring that future search results are arranged in a way that aligns with user preferences and reduces search time
2Productivity
If the arrangement order of search results is changed frequently based on user selections, then users can find desired targets more quickly, but the system complexity increases due to continuous reordering operations
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing multiple possible arrangement orders of search results based on different criteria (popularity, price, dictionary order, and user-specific patterns). When a user selects a target, the system has already prepared alternative arrangements and can quickly switch between them without performing complex reordering operations from scratch, thus reducing computational complexity while maintaining high productivity

AI summary
An information processing apparatus allows a user to easily find information about search targets which the user is likely to desire. Pieces of information about a plurality of searched search targets displayed as a search result include attribute values of search targets. The information processing apparatus specifies information selected by the user from displayed information, and compares an attribute value of a selected search target, with attribute values of search targets associated with display rankings which are higher than a display ranking of the selected search target associated with the specified information. When the attribute value of the selected search target is more advantageous for the user, the information processing apparatus performs control such that information about search targets whose attribute values are more advantageous for the user than that of the selected search target changes to a display mode which is more easily visually checked than the information about search targets whose attribute values are more disadvantageous for the user than that of the selected search target.
