Opinion-Based Response Generation Through Selective Entity Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing natural language processing systems struggle to effectively incorporate opinion-based information in responses to user inputs, limiting the depth and relevance of user interactions.
Innovation Solution
A system is developed to determine when opinion-based information is required for a response, perform entity extraction, and select relevant opinions from a knowledge base to generate a response, incorporating sentiment analysis and machine learning models to enhance user interaction.

Engineering Contradiction Analysis
1Loss of information
If traditional natural language processing systems are used to generate responses, then the system complexity remains low, but the relevance and informativeness of responses to user inputs is limited
Solution Approach 1:
The system segments the response generation process into distinct modules: an opinion detection component that identifies when opinion-based information is needed, an entity extraction component that retrieves relevant entities, and a response generation component that synthesizes the final response. This segmentation allows the system to incorporate opinion-based information only when necessary, rather than processing all inputs through complex opinion analysis, thus reducing overall system complexity while preventing information loss.
Solution Approach 2:
The opinion detection component performs preliminary analysis of user inputs to determine whether opinion-based information is required before proceeding to entity extraction and response generation. This preliminary action filters out inputs that do not require opinion analysis, preventing unnecessary processing complexity while ensuring that opinion-based information is captured when needed.
2Reliability
If opinion-based information is incorporated into responses, then the relevance and user experience are improved, but the processing time and computational resources increase
Solution Approach 1:
The system applies partial action by selectively processing only those user inputs that require opinion-based information. The opinion detection component identifies specific input types (e.g., questions about preferences, experiences, or subjective evaluations) and routes only these through the opinion extraction and response generation pipeline, while other inputs are handled through simpler processing paths, thus reducing overall processing time while maintaining response relevance when needed.
Solution Approach 2:
The opinion detection component autonomously determines whether opinion-based information is required for each user input without requiring manual configuration or external guidance. This self-service capability allows the system to dynamically adjust its processing depth based on input characteristics, optimizing the balance between response relevance and processing efficiency.

AI summary
Techniques for generating opinion-based content responsive to a user input are described. The system may receive a user input, and determine dialog context data corresponding to a dialog between a user and the system, and including the user input. The system may determine generation of content responsive to the user input requires opinion-based knowledge, and may extract entities from the dialog context data, and determine natural language data of a knowledge base that includes entities similar to the extracted entities. The system may processes the natural language data and the dialog context data to determine a subset of the natural language data that is responsive to the user input. The system may generate output data responsive to the user input using the responsive natural language data and the dialog context.
