Multilingual and Multi-Aspect Hate Speech Analysis (D19-1)
Copied to clipboard
| Challenge: | Current research on hate speech analysis is oriented towards monolingual and single classification tasks. |
| Approach: | They propose to use a multilingual multi-aspect hate speech analysis dataset to test current methods . they evaluate the dataset in various classification settings and discuss how to leverage annotations . |
| Outcome: | The proposed dataset can be used to improve hate speech detection and classification in general. |
Global Constraints with Prompting for Zero-Shot Event Argument Classification (2023.findings-eacl)
Copied to clipboard
| Challenge: | Existing zero-shot trigger extraction models require annotations, which is not practical for open-domain applications. |
| Approach: | They propose to use global constraints with prompting to tackle event argument classification without annotation and task-specific training. |
| Outcome: | The proposed model outperforms the best zero-shot baselines by 12.5% and 10.9% F1 on ACE and ERE with given argument spans and by 4.3% and 3.3% F1 without given argument spas. |
