Dynamic Response Sentence Generation via Multi-Stage Query Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dialogue systems struggle to create flexible and dynamic response sentences, especially in real-time situations, due to their reliance on pre-defined dialogue scenarios, leading to monotony and increased costs from requiring numerous scenario preparations.
Innovation Solution
A response sentence creation device that acquires situational information and trigger data to dynamically create queries and derive answers, combining them to generate contextually appropriate responses, reducing the need for extensive scenario preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a response sentence is created on the basis of a dialogue scenario (fixed phrase) prepared in advance, then the system structure is simple, but the response sentence becomes monotonous and cannot provide flexible responses to changing situations
Solution Approach 1:
The patent transforms the static dialogue scenario system into a dynamic one by introducing real-time situation acquisition and multi-layered query generation. The system now adapts its responses based on current situational context (time, location, user state) rather than relying solely on pre-defined scenarios, enabling flexible responses without requiring complete scenario coverage for all possible situations
Solution Approach 2:
The patent segments the response generation process into multiple independent modules: situation acquisition, first query generation, first answer derivation, second query generation, and second answer derivation. This modular architecture allows each component to function independently and contributes to the overall response flexibility without increasing overall system complexity
2Adaptability or versatility
If a large number of dialogue scenarios (fixed phrases) are prepared to provide flexible response sentences, then response flexibility improves, but costs increase
Solution Approach 1:
Instead of preparing complete dialogue scenarios for all possible situations (excessive action), the patent generates queries and answers partially on-demand based on actual situational needs. The system creates only the necessary first and second queries relevant to the current situation, avoiding the resource expenditure of preparing comprehensive scenario libraries
Solution Approach 2:
The patent changes the fundamental parameter of response generation from static scenario selection to dynamic query-based answer synthesis. By transforming the approach from using fixed phrases to generating answers through multi-layered queries, the system achieves flexibility without requiring large quantities of pre-prepared dialogue scenarios
3Manufacturing precision
If multi-layered queries are dynamically created based on derived answers, then response appropriateness improves, but processing complexity increases
Solution Approach 1:
The patent implements dynamic query creation where the second query is generated based on the result of the first query and the current situation. This dynamic adaptation allows the system to refine its information gathering process in real-time, improving response appropriateness by asking follow-up questions that are contextually relevant rather than using static predetermined query sequences
Solution Approach 2:
The patent incorporates feedback mechanisms where the answer derived from the first query feeds into the creation of the second query. This feedback loop allows the system to adjust its information gathering strategy based on what has already been learned, improving response precision while managing processing complexity through intelligent query refinement rather than exhaustive scenario matching
