| Challenge: | Existing studies on toxic content in online communities are limited by the scarcity of data that align textual content with comprehensive social interactions. |
| Approach: | They propose a user-aware hate speech detection framework that effectively fuses textual semantics with social interaction representations to provide pragmatic context for disambiguation. |
| Outcome: | The proposed framework outperforms strong text-only baselines by over 3.6%, validating the critical role of social context in enhancing detection accuracy. |
