摘　　要：科技文献问答系统能以自然语言对话的方式为用户提供高水平的知识服务。针对语义解析型知识图谱问答系统存在跨领域适应性弱及现有基于深度学习、大模型的问答系统存在结果可解释性差且难以溯源的问题,提出基于句式特点的中文问题分类方法,并设计基于Pipeline方法的中文科技文献问答系统框架。实验结果表明,基于句式特点的问题分类具有不依赖于特定领域的特点且在效果上与基于意图的问题分类基本相当,基于Pipeline的问题解析方法能有效地将问题转化为知识图谱查询语句,从而满足用户对自动问答结果可解释、可溯源的基本需求。The Q&A system of scientific and technical literature can provide high-level knowledge services for researchers with natural language.But the current semantic parsing-based knowledge graph Q&A system has poor cross-domain adaptability and Q&A systems based on deep learning or large language model suffer from poor interpretability and traceability of results.Aiming to address these issues,this article proposed a Chinese question categorical method based on sentence patterns and designed a Pipeline based framework for the Q&A system of Chinese scientific and technical literature.The experimental results show that question classification based on sentence patterns does not rely on specific domains and its effectiveness is basically comparable to the question classification based on intentions.The Pipeline-based question parsing method can effectively transform questions into knowledge graph query statements and effectively meets users’need for Q&A answers with interpretability and traceability of results.
