Improving the performance of large language models (LLMs) in complex question-answering (QA) scenarios has always been a research focal point. Recent studies have attempted to enhance LLMs' performance by combining step-wise planning with external retrieval. While effective for advanced models like GPT-3.5, smaller LLMs face challenges in decomposing complex questions, necessitating supervised fine-tuning. Previous work has relied on manual annotation and knowledge distillation from teacher LLMs, which are time-consuming and not accurate enough. In this paper, we introduce a novel framework for enhancing LLMs' planning capabilities by using planning data derived from knowledge graphs (KGs). LLMs fine-tuned with this data have improved planning capabilities, better equipping them to handle complex QA tasks that involve retrieval. Evaluations on multiple datasets, including our newly proposed benchmark, highlight the effectiveness of our framework and the benefits of KG-derived planning data.

使用来自知识图谱的规划数据，我们介绍了一种增强大型语言模型在复杂问答任务中的性能的新框架，通过使用这些数据对LLMs进行微调，提高其规划能力，更好地处理涉及检索的复杂QA任务。我们的框架在多个数据集上进行评估，包括我们提出的新基准，突出了其有效性和知识图谱派生规划数据的好处。
