ABSTRACT

The main objectives of this study are, first, to analyse the interactive metadiscourse devices used in engineering, medicine and linguistics and the identities represented; second, to identify the visual metadiscourse elements employed in the three identities constructed in the three specific settings and, finally, to classify and compare the multimodal metadiscourse used to cohere the different parts of digital academic discourse with the aim of guiding the reader textually as well as visually. To this end, academic papers were collected from journals which belonged to the specific fields of linguistics, engineering and medicine. The corpus was analysed to identify and classify the data. The results showed that there were in fact differences in the way academic writers used multimodal metadiscourse and constructed and represented their identity. The study revealed that engineers used visual metadiscourse more frequently, while linguistic researchers preferred the use of textual metadiscourse. Finally, conclusions were drawn.

摘要

本研究的主要目标是，首先，分析工程、医学和语言学中使用的交互式元话语设备及其所代表的身份；其次，确定在三种特定环境中构建的三种身份中所采用的视觉元话语元素，最后，对用于凝聚数字学术话语不同部分的多模态元话语进行分类和比较，目的是在文本上也引导读者作为视觉。为此，从属于语言学、工程和医学特定领域的期刊中收集了学术论文。分析语料库以识别和分类数据。结果表明，学术作家在使用多模态元话语、构建和表达身份的方式上实际上存在差异。研究表明，工程师更频繁地使用视觉元话语，而语言研究人员更喜欢使用文本元话语。最后得出了结论。
