Cover Story: Social media overflows with emotion, yet that emotion is rarely evenly distributed: in heated public debate, a few feelings dominate while others appear only rarely. This study asks a deceptively simple question: which computational method best detects emotion under these realistic, imbalanced conditions? Using a human-coded gold standard of conflict-related tweets, the authors benchmark 14 approaches, ranging from emotion lexicons and classical classifiers to deep learning and transformer models. Transformer models clearly lead, and those fine-tuned specifically for emotion best capture the rare categories that others miss. Yet no model fully matches human coders, and newer or larger architectures do not automatically win. The result is practical guidance for choosing emotion-detection tools in messy, real-world social media research. View this paper
