摘　　要：多选题自动生成属自然语言处理领域难题,其子任务有问题生成、答案生成、干扰项生成等尖端任务,虽前人对三者均有研究,但鲜有文献将其整合.提出多选题自动生成模型,对模型的问题生成、答案生成和干扰项生成等开展理论分析,并基于T5开展自动问题生成和答案生成的实验.实验表明,本模型能根据用户输入文本生成多项选择题,问题质量比纯T5模型的BLEU指标高约1个点,其它指标也略有提升.鉴于干扰项生成属前沿难题,文章仅作理论分析.The automatic generation of multiple-choice questions,whose subtasks include cutting-edge tasks such as question generation,answer generation,and distractor generation,is a new difficulty in the NLP field.Although previous studies have done on these three subtasks,few studies have tried to unify them.A multiple-choice question automatic generation model was proposed,theoretical analysis was made on the model’s question generation,answer generation,and distractor generation modules,and experiments on automatic question generation and answer generation based on T5 was conducted.The experiments showed that this model can generate multiple-choice questions based on user input text,and the question quality was about 1 point higher than the BLEU against the pure T5 model,and other metrics are also slightly improved.A theoretical analysis was made on the generation of distractor.
