Persona Knowledge-Aligned Prompt Tuning for Debate Argument Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating the persuasiveness of arguments in online debates lack integration of psychological principles, relying primarily on linguistic features and discourse structures, which limits their effectiveness in capturing the complex factors influencing argument persuasiveness.
Innovation Solution
A persona knowledge-aligned framework is introduced, utilizing prompt tuning to inject psychological information into smaller language models, allowing them to assess the persuasiveness and impact of online debate arguments by considering persona knowledge dimensions such as stance, argument, characters, and intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional linguistic and discourse-based methods are used for argument evaluation, then the evaluation process remains simple and computationally efficient, but the accuracy and depth of persuasiveness assessment are limited
Solution Approach 1:
The patent introduces persona knowledge as an intermediary layer between the argument text and the evaluation process. This persona knowledge, derived from psychological principles, acts as a mediator that enriches the evaluation by incorporating communicator characteristics, audience factors, and contextual elements without requiring complete system rearchitecture
Solution Approach 2:
The evaluation framework combines multiple knowledge domains (linguistic analysis, discourse structures, and psychological persona knowledge) into a composite assessment system. This composite approach integrates diverse information sources to achieve more accurate persuasiveness evaluation while managing complexity through structured integration
2Adaptability or versatility
If psychological principles are integrated into argument evaluation, then the comprehensiveness of persuasiveness assessment improves, but the difficulty of implementation and computational complexity increase
Solution Approach 1:
The patent segments psychological knowledge into distinct persona dimensions (communicator characteristics, audience factors, contextual elements). This segmentation allows the complex psychological evaluation to be broken down into manageable components that can be processed systematically, reducing implementation difficulty while maintaining comprehensiveness
Solution Approach 2:
The persona knowledge framework is designed to be universally applicable across different argument types, topics, and debate contexts. By creating a multi-functional evaluation structure that can adapt to various scenarios, the system achieves high comprehensiveness without proportionally increasing implementation complexity
3Loss of information
If persona knowledge from large language models is used, then the depth of psychological insight in evaluation improves, but the computational resources and processing time required increase
Solution Approach 1:
The patent extracts only the essential persona knowledge elements needed for argument evaluation from large language models, rather than utilizing the complete model capabilities. This extraction process isolates the relevant psychological information (communicator characteristics, audience factors, contextual elements) while discarding unnecessary computational overhead, thereby reducing resource consumption while maintaining information depth

AI summary
A method and a system for automatic evaluation of online debate arguments are provided. The method includes: defining multiple persona knowledge dimensions; tailor-making a prompt template according to the defined persona knowledge dimensions to generate a persona knowledge eliciting prompt; inputting the persona knowledge eliciting prompt to a pretrained language model to elicit persona knowledge; associating the elicited persona knowledge and the context and argument in the prompt to construct a knowledge-aligned prompt; and utilizing the knowledge-aligned prompt to fine-tune a debate evaluation model to evaluate persuasiveness/impact of the online debate arguments. The present invention can be applied to digital platforms equipped with tools to facilitate virtual discussions, incorporating features such as real-time feedback, interactive interfaces, and enhanced accessibility options to improve the overall debate experience, expand the range of platform participants, and thus make debates easier to understand and more attractive.
