Dynamic Response Threshold Adjustment in Dialogue Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic dialogue systems face challenges in providing high-quality responses due to static response thresholds, which can lead to frequent incorrect classifications and user frustration, as they do not adapt dynamically to user feedback and confidence levels.
Innovation Solution
The system dynamically adjusts response thresholds based on user feedback and confidence levels, using a threshold modification policy that increases or decreases thresholds based on user input, thereby improving response accuracy and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static response thresholds are used in automatic dialogue systems, then the system structure is simple and easy to implement, but the classification accuracy deteriorates and user frustration increases due to inability to adapt to feedback
Solution Approach 1:
The patent implements dynamic response thresholds that automatically adjust based on system performance metrics and user feedback. The thresholds transition from static predetermined values to dynamic values that adapt in real-time, resolving the contradiction by making the system flexible and adaptive while maintaining manageable complexity through automated adjustment mechanisms
Solution Approach 2:
The patent incorporates feedback loops where classification performance and user interactions are continuously monitored. This feedback drives automatic threshold adjustments, enabling the system to learn from mistakes and improve accuracy over time without requiring complex manual intervention or retraining processes
2Reliability
If clarification questions are asked frequently to improve accuracy, then classification reliability improves, but user experience deteriorates due to increased interaction overhead
Solution Approach 1:
The patent applies partial action by asking clarification questions selectively rather than frequently. The dynamic thresholds determine when clarification is truly necessary versus when the system can confidently proceed, reducing unnecessary user interactions while maintaining high classification reliability through targeted disambiguation only when confidence levels indicate potential errors
3Ease of operation
If response thresholds are lowered to reduce clarification questions, then user interaction ease improves, but classification accuracy deteriorates leading to more incorrect responses
Solution Approach 1:
The patent uses dynamic thresholds that automatically adjust their stringency based on real-time performance monitoring. When classification precision drops below acceptable levels, thresholds automatically tighten; when performance is strong, thresholds relax to enable faster responses, thus resolving the contradiction between speed and precision through adaptive control

AI summary
Method and apparatus improves the quality of responses from an automatic dialogue system by dynamically adjusting response thresholds. More particularly, the automatic dialogue system may dynamically determine response threshold values in response to user feedback. The response threshold values may be used to evaluate a confidence value. The confidence value may be assigned to or otherwise associated with an input class, or user intent. The system may automatically adjust the response threshold values to provide a better user experience as the amount of user-interaction with the system increases.
