Identifying and Measuring Annotator Bias Based on Annotators’ Demographic Characteristics
TL;DR: This work investigates annotator bias using classification models trained on data from demographically distinct annotator groups, and shows that demographic features, such as first language, age, and education, correlate with significant performance differences.
