Researchers have identified significant label errors in datasets for individual-level Natural Language Understanding (NLU) tasks like stance detection and sentiment analysis, with error rates reaching up to 31.7%. To address this, they propose a new annotation guideline that incorporates an individual's other posts to better capture subjective perspectives. Experiments using this guideline and large language models like GPT-4o and Llama3-70B showed that incorporating individual factors improved model accuracy to over 87% on re-annotated datasets, highlighting the importance of this approach for future NLU dataset creation.
