The data paper is an emerging academic genre that focuses on the description of research data objects. However, there is a lack of empirical knowledge about this rising genre in quantitative science studies, particularly from the perspective of its linguistic features. To fill this gap, this research aims to offer a first quantitative examination of which rhetorical moves-rhetorical units performing a coherent narrative function-are used in data paper abstracts, as well as how these moves are used. To this end, we developed a new classification scheme for rhetorical moves in data paper abstracts by expanding a well-received system that focuses on English-language research article abstracts. We used this expanded scheme to classify and analyze rhetorical moves used in two flagship data journals, Scientific Data and Data in Brief. We found that data papers exhibit a combination of IMRaD- and data-oriented moves and that the usage differences between the journals can be largely explained by journal policies concerning abstract and paper structure. This research offers a novel examination of how the data paper, a novel data-oriented knowledge representation, is composed, which greatly contributes to a deeper understanding of data and data publication in the scholarly communication system.

翻译：数据文件是一个新兴的学术流,侧重于对研究数据对象的描述。然而,对于定量科学研究中这种不断上升的流派,我们缺乏经验知识,特别是从语言特征的角度来看,填补这一空白。为填补这一空白,这一研究旨在首次对数据文件摘要中使用的具有连贯叙事功能的单词移动 -- -- 风湿体单元,以及这些动作的使用方式进行定量审查。为此目的,我们为数据文件摘要中的虚言动作制定了一个新的分类办法,方法是扩大一个以英文研究文章摘要为重点的广为人知的系统。我们利用这一扩大的办法,对两个旗舰数据杂志《科学数据和数据简报》中使用的辞藻动作进行了分类和分析。我们发现,数据文件展示了IMRAD和数据导向的组合,而两个期刊之间的使用差异在很大程度上可以用关于抽象和纸质结构的期刊政策来解释。这一研究对数据文件的构成方式进行了新颖的审查,一种面向数据的知识表述方式,极大地有助于更深入地了解学术通信系统中的数据和数据出版情况。
