Temporal Simultaneity Predicts Annotation Quality in Sentiment Corpora. arXiv:2605.27239. A Setswana sentiment dataset (3,565 tweets, three native-speaker annotators across eight batches): overall agreement was κ = 0.76, but items labelled within a minute of each other reached κ = 0.98 while items labelled more than a day apart fell to κ = 0.65, revealing annotator drift over time. arxiv.org/abs/2605.27239
