abstract = "To alleviate the high cost of manually annotating Question Answering (QA) datasets, Question Generation (QG) requires the model to generate a question related to the given answer and passage. This work primarily focuses on Multi-Span Question Generation (MSQG), where the generated question corresponds to multiple candidate answers. Existing QG methods may not suit MSQG as they typically overlook the correlation between the candidate answers and generate trivial questions, which limits the quality of the synthetic datasets. Based on the observation that relevant entities typically share the same relationship with the same entity, we propose REGULAR, a framework of RElation-GUided MuLti-SpAn Question GeneRation. REGULAR first converts passages into relation graphs and extracts candidate answers from the relation graphs. Then, REGULAR utilizes a QG model to generate a set of candidate questions and a QA model to obtain the best question. We construct over 100,000 questions using Wikipedia corpora, named REGULAR-WIKI, and conduct experiments to compare our synthetic datasets with other synthetic QA datasets. The experiment results show that models trained with REGULAR-WIKI achieve the best performance. We also conduct ablation studies and statistical analysis to verify the quality of our synthetic dataset. Our code and data are available at https://github.com/PluseLin/REGULAR."
