The Effectiveness of LLMs as Annotators: A Comparative Overview and Empirical Analysis of Direct Representation

AbstractRecent studies focus on exploring the capability of Large Language Models (LLMs) for data annotation. Our work, firstly, offers a comparative overview of twelve such studies that investigate labelling with LLMs, particularly focusing on classification tasks. Secondly, we present an empirical analysis that examines the degree of alignment between the opinion distributions returned by GPT and those provided by human annotators across four subjective datasets. Our analysis supports a minority of studies that are considering diverse perspectives when evaluating data annotation tasks and highlights the need for further research in this direction.
