摘要:

科学极端摘要(TLDR)旨在形成科学论文的超短摘要。由于需要大量的人工注释和领域专业知识,以前管理科学TLDR数据集的努力未能扩大规模。在本文中,我们提出了一个简单而有效的方法来自动提取TLDR摘要的科学论文从他们的引文文本。基于所提出的方法,我们创建了一个没有人类注释的新基准CiteSum,它比以前的人类策划数据集SciTLDR大30倍左右。我们对CiteSum进行全面分析,检查其数据特征并建立强大的基线。我们通过使在CiteSum(名为CITES)上预训练的模型适应监督有限的新任务和领域,进一步证明了CiteSum的有用性。对于科学的极端总结,CITES在SciTLDR上的表现优于大多数完全监督的方法,无需任何微调,并且仅用128个例子就获得了最先进的结果。对于新闻极端摘要,CITES在XSum上实现了其基础模型(未在CiteSum上预训练)的显著增益,例如,+7.2 ROUGE-1 zero-shot性能和最先进的Few-Shot性能。对于新闻标题生成,CITES在Gigaword上的无监督和zero-shot方法中表现最好。我们的数据集和代码可以在https://github.com/morningmoni/CiteSum上找到。

英文摘要:

Scientific extreme summarization (TLDR) aims to form ultra-short summaries of scientific papers. Previous efforts on curating scientific TLDR datasets failed to scale up due to the heavy human annotation and domain expertise required. In this paper, we propose a simple yet effective approach to automatically extracting TLDR summaries for scientific papers from their citation texts. Based on the proposed approach, we create a new benchmark CiteSum without human annotation, which is around 30 times larger than the previous human-curated dataset SciTLDR. We conduct a comprehensive analysis of CiteSum, examining its data characteristics and establishing strong baselines. We further demonstrate the usefulness of CiteSum by adapting models pre-trained on CiteSum (named CITES) to new tasks and domains with limited supervision. For scientific extreme summarization, CITES outperforms most fully-supervised methods on SciTLDR without any fine-tuning and obtains state-of-the-art results with only 128 examples. For news extreme summarization, CITES achieves significant gains on XSum over its base model (not pre-trained on CiteSum), e.g., +7.2 ROUGE-1 zero-shot performance and state-of-the-art few-shot performance. For news headline generation, CITES performs the best among unsupervised and zero-shot methods on Gigaword. Our dataset and code can be found at https://github.com/morningmoni/CiteSum.
