Abstract

This paper adopts a local grammar approach to explore how the semantic patterns of the discourse act of graphic data commentary in economics research articles have changed over the recent three decades. Based on the comparable corpora of research articles of economics from three time periods (i.e. 1990-1999, 2000–2009, and 2010–2019), we extracted instances of graphic data commentary and performed local grammar analyses to obtain three groups of semantic patterns (i.e. the local grammar patterns). By comparing the frequency distributions of these patterns across the corpora, we find that over the 30 years graphic data commentary has changed to become more concise, interactive, and interpretive. Behind these changes, we argue that the changing social-cultural factors and the disciplinary epistemology of economics may have driven economists to strategically modify the semantic patterns of graphic data commentary. This study also discusses the pedagogical value of the changing patterns of graphic data commentary for current local grammar based EAP teaching.

追踪经济学研究文章中图形数据评论随时间推移而变化的模式：地方语法研究

本文采用局部语法方法探讨了近三十年来经济学研究文章中图形数据评论这一话语行为的语义模式是如何变化的。基于1990-1999年、2000-2009年和2010-2019年三个时间段的经济学研究文章可比语料库，我们提取了图形数据评论的实例，并进行了局部语法分析，得到了三组语义模式（即局部语法模式）。通过比较这些模式在不同语料库中的频率分布，我们发现 30 年来图形数据评论发生了变化，变得更加简洁、更具互动性和解释性。在这些变化的背后，我们认为不断变化的社会文化因素和经济学的学科认识论可能促使经济学家战略性地修改图表数据评论的语义模式。本研究还讨论了图形数据注释模式的变化对于当前基于本地语法的 EAP 教学的教学价值。
