Multi-Goal Dialog Generation Using Simulators and Templates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current speech recognition systems struggle to understand multiple goals expressed by users in goal-oriented dialog sessions, often failing to recognize romantic intentions or location-specific requests, leading to inappropriate suggestions.
Innovation Solution
A system and method for dialog generation that includes a client providing dialog template information, API information, and sample interactions to train a multi-goal dialog system, using an agent simulator and user simulator to generate dialog outlines, and a natural language component to create context-aware responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If speech recognition systems use basic natural-language understanding processing, then they can process simple user commands, but they fail to understand multiple goals expressed by users in goal-oriented dialog sessions
Solution Approach 1:
The system segments the dialog understanding task into multiple independent goal detection modules. Each module focuses on identifying a specific user goal from the dialog input, allowing the system to handle multiple goals simultaneously without overwhelming complexity. The dialog state tracker divides the overall task into discrete state updates for each identified goal.
Solution Approach 2:
The dialog state tracker serves multiple functions: it tracks entities, determines user goals, manages dialog state, and coordinates with multiple skills. This multi-functional component consolidates what would otherwise require separate systems, achieving high adaptability while controlling overall system complexity through a centralized tracking mechanism.
2Measurement precision
If the system tracks all required entities and generates context-aware responses, then it provides appropriate suggestions, but it requires complex processing of dialog templates, API information, and sample interactions
Solution Approach 1:
The system performs preliminary processing by pre-defining dialog templates with expected entities and structures. During actual dialog processing, the system matches user input against these pre-defined templates, significantly reducing the complexity of real-time analysis. Entity extraction and goal identification are performed by matching against predetermined patterns rather than analyzing from scratch.
Solution Approach 2:
The dialog state tracker acts as an intermediary component that bridges the gap between raw user input and the multiple skills (restaurant, movie, etc.). It consolidates information from dialog templates, API responses, and user inputs, then presents a unified dialog state to the appropriate skill handlers, simplifying the overall processing architecture.
3Reliability
If the system uses multiple simulators to generate dialog outlines, then it creates realistic training data, but it increases the complexity of training the multi-goal dialog system
Solution Approach 1:
The agent simulator and user simulator work together in a self-service manner to generate training data without requiring manual annotation. The agent simulator generates realistic agent responses based on dialog templates, while the user simulator generates corresponding user inputs. This automated data generation process improves training data quality while the modular simulator architecture keeps training complexity manageable.
Data Source
AI summary
A dialog generator receives data corresponding to desired dialog, such as application programming interface (API) information and sample dialog. A first model corresponding to an agent simulator and a second model corresponding to a user simulator take turns creating a plurality of dialog outlines of the desired dialog. The dialog generator may determine that one or more additional APIs are relevant to the dialog and may create further dialog outlines related thereto. The dialog outlines are converted to natural dialog to generate the dialog.
