摘要:

跟踪科学挑战,进步和新兴方向是研究的基本组成部分。然而,研究人员面临着大量的论文,阻碍了重要知识的发现。在生物医学中,这直接影响人类的生活。为了解决这个问题,我们提出了一个新的任务,提取和搜索的科学挑战和方向,以促进快速知识发现。我们构建并发布了一个专家注释的文本语料库,该语料库从全长论文中采样,标记有新颖的语义类别,这些类别概括了许多类型的挑战和方向。我们专注于与COVID-19大流行相关的大量跨学科工作,从生物医学到人工智能和经济学等领域。我们应用一个基于数据训练的模型来识别整个语料库中的挑战和方向,并构建一个专用的搜索引擎。在19名研究人员和临床医生使用我们的系统进行的实验中,我们在帮助知识发现方面优于流行的科学搜索引擎。最后,我们展示了在我们的资源上训练的模型可以推广到更广泛的生物医学领域和AI论文,突出了其广泛的实用性。我们公开我们的数据、模型和搜索引擎。https://challenges.apps.allenai.org/

英文摘要:

Keeping track of scientific challenges, advances and emerging directions is a fundamental part of research. However, researchers face a flood of papers that hinders discovery of important knowledge. In biomedicine, this directly impacts human lives. To address this problem, we present a novel task of extraction and search of scientific challenges and directions, to facilitate rapid knowledge discovery. We construct and release an expert-annotated corpus of texts sampled from full-length papers, labeled with novel semantic categories that generalize across many types of challenges and directions. We focus on a large corpus of interdisciplinary work relating to the COVID-19 pandemic, ranging from biomedicine to areas such as AI and economics. We apply a model trained on our data to identify challenges and directions across the corpus and build a dedicated search engine. In experiments with 19 researchers and clinicians using our system, we outperform a popular scientific search engine in assisting knowledge discovery. Finally, we show that models trained on our resource generalize to the wider biomedical domain and to AI papers, highlighting its broad utility. We make our data, model and search engine publicly available. https://challenges.apps.allenai.org/
