Evaluating Contribution Reliability via User Activity Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contribution information evaluation systems fail to distinguish between users who visit facilities regularly and those who only pass by, leading to unreliable evaluation of contribution information reliability.
Innovation Solution
An information processing device and system that evaluate contribution information reliability based on the range of activity of the user, using positional information, time zones, distance, and usage history, such as commuter tickets and e-money records, to determine if the contributor has a genuine connection to the facility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contribution information reliability is evaluated based only on whether the user visited the facility, then the evaluation is simple to implement, but it cannot distinguish between regular visitors and occasional passersby, reducing evaluation accuracy
Solution Approach 1:
The patent segments the evaluation process into multiple components: basic visit verification, range of activity analysis, and reliability scoring. By dividing the evaluation into these distinct segments, the system achieves higher accuracy without overwhelming complexity at any single stage.
Solution Approach 2:
The patent adds a new dimension to the evaluation by incorporating spatial analysis of the user's range of activity. Instead of evaluating only whether the user visited the facility, the system analyzes the geographic area the user covers and how the facility fits within that range, thereby improving measurement precision.
2Reliability
If the system analyzes detailed positional information and range of activity to evaluate reliability, then evaluation accuracy improves, but information processing requirements and system complexity increase
Solution Approach 1:
The patent performs preliminary analysis of the user's range of activity before evaluating specific contribution information. By pre-processing and storing the spatial characteristics of the user's activity area, the system reduces the complexity of real-time evaluation while maintaining high reliability.
Solution Approach 2:
The patent introduces the concept of 'range of activity' as an intermediary that mediates between raw positional information and reliability evaluation. This intermediary abstraction simplifies the processing by providing a pre-computed spatial context that can be directly applied to evaluate contribution information without analyzing every positional data point.
3Measurement precision
If the system uses multiple evaluation criteria including time zone and distance, then evaluation precision improves, but the number of processing parameters and system complexity increase
Solution Approach 1:
The patent applies different evaluation criteria with varying weights based on local conditions. For example, distance and time zone criteria are applied differently depending on the specific facility and user context. This localized approach improves precision without requiring uniform complex processing for all evaluations.

AI summary
An information processing device includes a range of activity information acquisition unit which acquires information of the range of activity that is an area that a user who contributes contribution information on a facility visits, and a reliability level evaluation unit which evaluates the level of reliability for the contribution information based on the information of the range of activity.
