Virtual Rating Device With Differential Time Costs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Online rating systems face challenges in providing high-quality information due to the lack of motivation for users to provide accurate assessments, leading to low-quality information, as users do not face direct benefits or costs for their ratings.
Innovation Solution
Implementing a differential time cost system for adjusting ratings, where greater differences in rating values incur higher time costs, encouraging only confident and motivated users to provide their assessments, thereby filtering out unreliable information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rating adjustment is made costless and easy, then user participation and quantity of ratings increase, but information quality deteriorates due to lack of motivation for accurate assessments
Solution Approach 1:
The patent changes the parameter of signaling cost from zero to variable time cost. By introducing differential time costs that scale with the magnitude of rating adjustments, the system transforms the rating act from costless to costly, thereby motivating users to provide more accurate and deliberate assessments while maintaining reasonable participation levels.
Solution Approach 2:
The patent implements dynamic time costs that adjust based on the specific rating behavior. The time cost is not fixed but varies dynamically with the difference between initial and adjusted ratings, creating a flexible signaling cost structure that adapts to user actions and maintains information quality across different rating scenarios.
2Measurement precision
If differential time costs are imposed on rating adjustments, then information quality improves by filtering unreliable signalers, but ease of operation deteriorates due to increased time investment required
Solution Approach 1:
The patent applies local quality by imposing time costs selectively rather than uniformly. The differential time cost structure means that small, incremental rating adjustments incur lower time costs while large, extreme adjustments incur higher time costs. This localized application of signaling cost allows users to rate easily when confident while discouraging careless extreme ratings, thus maintaining ease of operation for legitimate uses while improving information quality.

AI summary
Disclosed is a virtual rating device that associate online ratings with differential time costs by endowing the graphical user interface that solicited ratings from the users with “physics,” including an initial (default) slider position and friction. When ratings are associated with differential time cost, scores correlated more strongly with objective service quality. The differential time costs optimize information when proportional to the deviation from the median score. Correlations between subjective rating scores and objective service performance can be further improved by boosting time costs for reporting extreme scores. The disclosed device lowers the sample size (and therefore costs) required for obtaining reliable, averaged crowd estimates. The disclosed device improves information quality in online rating and feedback systems. By endowing a rating widget with virtual friction to increase the time cost for reporting extreme scores, one can obtain a more reliable crowd estimates of quality. Implications include improving accuracy of evaluations in e-commerce, and the approach can be generalized and tested in a variety of large-scale online communication systems.
