Multi-document scientific summarization can extract and organize important
information from an abundant collection of papers, arousing widespread
attention recently. However, existing efforts focus on producing lengthy
overviews lacking a clear and logical hierarchy. To alleviate this problem, we
present an atomic and challenging task named Hierarchical Catalogue Generation
for Literature Review (HiCatGLR), which aims to generate a hierarchical
catalogue for a review paper given various references. We carefully construct a
novel English Hierarchical Catalogues of Literature Reviews Dataset (HiCaD)
with 13.8k literature review catalogues and 120k reference papers, where we
benchmark diverse experiments via the end-to-end and pipeline methods. To
accurately assess the model performance, we design evaluation metrics for
similarity to ground truth from semantics and structure. Besides, our extensive
analyses verify the high quality of our dataset and the effectiveness of our
evaluation metrics. Furthermore, we discuss potential directions for this task
to motivate future research
