Preference Estimation Device for Relocation Site Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for user preference estimation in relocation site selection often lead to a 'convincing process' that deviates from the user's true preference, resulting in decreased accuracy due to continued questioning after the true preference is reached, causing users to be directed to options that are not aligned with their actual preferences.
Innovation Solution
A computer-readable medium and estimation method that determines a 'preference-reached mode' based on user answer logs, adjusting inquiry options to prevent deviation from the true preference by identifying a matching option trend and changing content accordingly, thereby inhibiting the convincing process from directing users away from their true preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system continues to execute inquiries and represent additional options after the user has reached their true preference, then the user can be convinced to check if they have reached the true preference, but the accuracy of estimating the user's preference deteriorates because the system directs the user to options deviating from the true preference
Solution Approach 1:
The system performs preliminary analysis of user answer logs to identify the preference-reached mode before continuing the convincing process. By detecting when the user has reached their true preference through log analysis, the system can take preliminary action to adjust subsequent inquiry options, preventing the user from being directed away from their true preference while still allowing the convincing process to occur.
Solution Approach 2:
The system dynamically adjusts the inquiry options based on the detected preference-reached mode. When the user is in preference-reached mode, the system changes the content of subsequent inquiries to maintain alignment with the user's true preference. This dynamic adjustment ensures that the convincing process continues without deteriorating preference estimation accuracy.
2Productivity
If the system asks multiple questions and repeatedly represents options to estimate user preference, then the preference estimation can be performed, but the user may repeat the convincing process after reaching true preference, causing the represented options to deviate from true preference
Solution Approach 1:
The system uses feedback from user answer logs to detect the preference-reached mode and adjust subsequent inquiry options. By continuously monitoring user responses and identifying when the user has reached their true preference, the system provides feedback-based adjustment to maintain option alignment with user preferences, preventing deviation during the convincing process.
Solution Approach 2:
The system changes the parameters of inquiry options based on the detected preference-reached mode. When the user is in preference-reached mode, the system modifies the content and characteristics of subsequent inquiries to ensure they remain aligned with the user's true preference, thereby maintaining estimation accuracy while continuing the preference estimation process.

AI summary
A search device, for each of a plurality of inquiries including a plurality of options, based on a log of answers of a respondent in the past, specifies a matching option corresponding to a trend of answers of the respondent from the plurality of options to be represented to the respondent. The search device, when an answer to the plurality of options is included in the matching option, determines that it is a preference-reached mode that is a mode where the estimating a preference of the user converges. The search device transmits, to the respondent, an inquiry including options, contents of the options included in the inquiry being changed depend on whether it is determined to be a preference-reached mode in the determining.
