How Do Moral Emotions Shape Political Participation? A Cross-Cultural Analysis of Online Petitions Using Language Models (2024.findings-acl)
Copied to clipboard
| Challenge: | Using cross-cultural online petition data, we examine how moral emotions influence user participation and political participation. |
| Approach: | They construct and share a moral emotion dataset comprising 50,000 petition sentences in Korean and English each, along with emotion labels annotated by a fine-tuned LLM. |
| Outcome: | The results show that moral emotions like other-suffering increase both forms of participation and help petitions go viral, while self-conscious have the opposite effect. |
