Utilizing ChatGPT for Efficient and Cost-Effective Text Annotation: A Comparative Study

High-quality labeled data is crucial for many NLP applications. It is used to train classifiers and assess the effectiveness of unsupervised models. Academic researchers often use labeled data to classify texts, filter social media data, or gauge mood and position. Previously, researchers relied on research assistants or freelancers from platforms like Amazon Mechanical Turk (MTurk) to annotate the data. However, there have been concerns about the decline in the quality of MTurk data.

To address this issue, researchers from the University of Zurich explored the potential of large language models (LLMs) for text annotation tasks. They specifically looked at ChatGPT, a language model that was made public in November 2022. They found that zero-shot ChatGPT classifications outperformed annotations from MTurk, both in terms of accuracy and intercoder agreement. ChatGPT also proved to be more affordable, costing only a fraction of what MTurk annotations would cost.

The researchers tested ChatGPT on a sample of 2,382 annotated tweets and found that it provided superior quality at a significantly lower cost compared to MTurk. They estimated that annotating 100,000 annotations would only cost around $300. This research demonstrates the potential of ChatGPT and other LLMs to revolutionize the data annotation process and disrupt the business models of platforms like MTurk.

While ChatGPT has shown promising results, further research is still needed to fully understand its performance in different contexts. Nevertheless, the findings highlight the value of LLMs in providing high-quality labeled data for NLP applications.

Benefits of Using ChatGPT for Annotation

ChatGPT offers several advantages over traditional annotation methods. Firstly, it provides high-quality annotations at a lower cost compared to hiring and training research assistants. Secondly, ChatGPT is versatile and can handle a variety of tasks and languages, making it suitable for diverse research projects. Lastly, using ChatGPT for annotation tasks can save researchers valuable time and resources, allowing them to focus on other aspects of their work.

Future Implications

The success of ChatGPT and other LLMs in text annotation tasks has significant implications for the field of NLP research. It offers a more accessible and cost-effective alternative to traditional annotation methods. This opens up opportunities for researchers to conduct large-scale studies, annotate more data, and build better training sets for supervised learning. As LLMs continue to advance, they are likely to play a transformative role in how researchers conduct data annotations and shape the future of NLP research.


High-quality labeled data is essential for NLP applications, and researchers have traditionally relied on methods like hiring research assistants or using platforms like MTurk for annotation tasks. However, the quality and cost-effectiveness of these methods have been a concern. The study conducted by researchers from the University of Zurich demonstrates the potential of large language models like ChatGPT for text annotation tasks. ChatGPT proved to be more accurate and affordable compared to MTurk, offering a promising alternative for researchers. Further research is needed to fully explore the capabilities of ChatGPT and other LLMs, but the findings present an exciting development in the field of NLP research.
