Researchers have developed a new framework for implicit sentiment analysis, a task that infers sentiment from context rather than explicit words. Their approach, inspired by cognitive appraisal theory, uses a multi-task learning framework with two auxiliary tasks: implicit sentiment detection and cognitive rationale generation. To mitigate task interference, they implemented a task-routed mixture-of-experts model where tasks sparsely combine shared experts, outperforming existing methods on implicit sentiment tasks. AI
