Research on guided keyword techniques for enhancing user query effectiveness in intelligent question answering for relay protection setting calculation

The application of intelligent question-answering (QA) technology in the power industry is continuously evolving, but existing systems still face challenges in terms of the effectiveness and accuracy of user queries. This paper proposes an optimization approach for guided keyword templates in the context of relay protection setting calculations within intelligent QA systems. By designing templates, the system helps users formulate clearer and more precise questions, thereby improving the quality of the answers. To address the issues of ambiguity and incompleteness in user queries, five categories of guided keyword templates are designed, along with two evaluation metrics: clarity enhancement and guidance enhancement. The experimental results show that the optimized queries significantly improve both the clarity and guidance of the questions, enhancing the quality of the system’s responses. The guided keyword template system designed in this paper demonstrates its advantages in improving question quality and provides valuable insights for the optimization of intelligent QA systems and for improving QA in other domains.
