This study investigated variation in the rhetorical and phraseological features of research article introductions among five social science disciplines. Our dataset consisted of the introduction sections of 500 published research articles from Anthropology, Applied Linguistics, Political Science, Psychology, and Sociology. All texts in the dataset were manually annotated for rhetorical moves and steps by a team of seven researchers using an extensively adapted version of Swales’ (2004) revised Create a Research Space (CARS) model. Our rhetorical and phraseological analysis of the corpus revealed substantial disciplinary variation in both the distribution of rhetorical move-steps and the associations between phrase-frames and rhetorical move-steps among the five social science disciplines. Our findings contribute to a better understanding of disciplinary variation in the rhetorical and linguistic features of research article writing and have useful implications for academic writing research and pedagogy.

本研究调查了五个社会科学学科之间研究文章介绍的修辞和用语特征的变化。我们的数据集包括来自人类学、应用语言学、政治学、心理学和社会学的 500 篇已发表研究文章的介绍部分。由七名研究人员组成的团队使用 Swales (2004) 修订的 Create a Research Space (CARS) 模型的广泛改编版本手动注释了数据集中的所有文本，以了解修辞动作和步骤。我们对语料库的修辞和用语分析揭示了五个社会科学学科中修辞动作步骤的分布以及短语框架和修辞动作步骤之间的关联的重大学科差异。
