Can GPT-4 learn to analyze moves in research article abstracts?

One of the most powerful and enduring ideas in written discourse analysis is that genres can be described in terms of the moves which structure a writer's purpose. Considerable research has sought to identify these distinct communicative acts, but analyses have been beset by problems of subjectivity, reliability and the time-consuming need for multiple coders to confirm analyses. In this paper we employ the affordances of GPT-4 to automate the annotation process by using natural language prompts. Focusing on abstracts from articles in four applied linguistics journals, we devise prompts which enable the model to identify moves effectively. The annotated outputs of these prompts were evaluated by two assessors with a third addressing disagreements. The results show that an 8-shot prompt was more effective than one using two, confirming that the inclusion of examples illustrating areas of variability can enhance GPT-4's ability to recognize multiple moves in a single sentence and reduce bias related to textual position. We suggest that GPT-4 offers considerable potential in automating this annotation process, when human actors with domain specific linguistic expertise inform the prompting process.

Using LLM-assisted Annotation for Corpus Linguistics: A Case Study of Local Grammar Analysis

Chatbots based on Large Language Models (LLMs) have shown strong capabilities in language understanding. In this study, we explore the potential of LLMs in assisting corpus-based linguistic studies through automatic annotation of texts with specific categories of linguistic information. Specifically, we examined to what extent LLMs understand the functional elements constituting the speech act of apology from a local grammar perspective, by comparing the performance of ChatGPT (powered by GPT-3.5), the Bing chatbot (powered by GPT-4), and a human coder in the annotation task. The results demonstrate that the Bing chatbot significantly outperformed ChatGPT in the task. Compared to human annotator, the overall performance of the Bing chatbot was slightly less satisfactory. However, it already achieved high F1 scores: 99.95% for the tag of APOLOGISING, 91.91% for REASON, 95.35% for APOLOGISER, 89.74% for APOLOGISEE, and 96.47% for INTENSIFIER. This suggests that it is feasible to use LLM-assisted annotation for local grammar analysis, together with human intervention on tags that are less accurately recognized by machine. We strongly advocate conducting future studies to evaluate the performance of LLMs in annotating other linguistic phenomena. These studies have the potential to offer valuable insights into the advancement of theories developed in corpus linguistics, as well into the linguistic capabilities of LLMs..
