Two new research papers explore advancements in Aspect-Based Sentiment Analysis (ABSA) using Large Language Models (LLMs). The first paper introduces "Multi-View Prompting" (LLM-MvP), a technique that combines schema-constrained decoding with prefix batching to achieve performance competitive with fine-tuned models while reducing computational costs. The second paper presents a controlled synthetic benchmark for educational ABSA, generated from 10,000 synthetic course reviews, which aims to address the scarcity of public aspect-labeled student feedback. This benchmark was used to evaluate various models, including BERT and GPT-based inference with gpt-5.2, demonstrating the task's difficulty and the potential for synthetic data transfer to real-world reviews.
