DiffuSent: Towards a Unified Diffusion Framework for Aspect-Based Sentiment Analysis
Researchers have introduced DiffuSent, a novel diffusion-based framework designed to unify various subtasks within Aspect-Based Sentiment Analysis (ABSA). This non-autoregressive model addresses limitations of previous generative approaches by refining aspect and opinion term boundaries through a diffusion process. Experiments show DiffuSent outperforms existing systems, particularly with multi-word terms, and offers significantly faster inference speeds. AI
