Dialogue Move Scripts for Multi-Device Dialogue Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dialogue management systems require significant engineering efforts to adapt to new domains due to variations in dialogue move requirements, interface representation, and domain-specific processes, limiting their flexibility and scalability in multi-application, multi-device spoken-language dialogue systems.
Innovation Solution
The Representation-Neutral Dialogue Systems (RNDS) implement an information-state update approach with Dialogue Move Scripts, Noun Phrase Resolution Scripts, and Activity Models, enabling seamless interaction with external components and allowing for easy customization and plug-and-play functionality across different devices and domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional dialogue management systems are used, then dialogue processing can be performed, but significant engineering efforts are required to adapt to new domains
Solution Approach 1:
The system segments dialogue management into independent, reusable components including Dialogue Move Scripts, Noun Phrase Resolution Scripts, and Activity Models. Each component handles a specific aspect of dialogue processing and can be independently configured for different domains, eliminating the need for comprehensive system reengineering when adapting to new domains.
Solution Approach 2:
The patent creates universal dialogue management infrastructure that serves multiple domains through standardized interfaces and reusable scripts. The Activity Models and Dialogue Move Scripts are designed to be domain-agnostic, allowing the same core system to handle diverse applications from automotive to healthcare domains without requiring domain-specific recoding of fundamental processing logic.
2Reliability
If dialogue systems are designed for specific domains, then domain-specific performance is improved, but flexibility to apply to new domains decreases
Solution Approach 1:
The system applies local quality by allowing domain-specific customization only where necessary through configurable scripts and models, while maintaining universal core processing logic. Each domain can override or customize specific Dialogue Move Scripts or Activity Models without affecting the overall system architecture, enabling both domain optimization and cross-domain flexibility.
3Adaptability or versatility
If VXML-based dialogue management infrastructure is used, then flexible implementation for new domains is enabled, but only shallow solutions to dialogue modeling issues are provided
Solution Approach 1:
The patent combines multiple specialized components (Dialogue Move Scripts, Noun Phrase Resolution Scripts, Activity Models, and VXML infrastructure) into a composite dialogue management system. This composite approach integrates the flexibility of VXML with deeper dialogue modeling capabilities, creating a system that both adapts easily to new domains and provides comprehensive solutions to complex dialogue modeling challenges.

AI summary
Representation-neutral dialogue systems and methods (“RNDS”) are described that include multi-application, multi-device spoken-language dialogue systems based on the information-state update approach. The RNDS includes representation-neutral core components of a dialogue system that provide scripted domain-specific extensions to routines such as dialogue move modeling and reference resolution, easy substitution of specific semantic representations and associated routines, and clean interfaces to external components for language-understanding (i.e., speech-recognition and parsing) and language-generation, and to domain-specific knowledge sources. The RNDS also allows seamless interaction with a community of devices.
