TL;DR
A novel Hybrid framework with Generation-guided Sequence Tagging (HyGST), which innovatively enhances task-relevant semantics by exploiting the intrinsic correlation between words and labels, which outperforms current EABSA methods.
A generative ACSA model that incorporates external knowledge is proposed, which retrieves fine-grained aspect-related terms from external knowledge bases and uses them to construct contrastive sentence pairs, generating enhanced aspect-related representations, thereby bridging the gap between the original text and pred...

This paper introduces the sentiment-aware chain-of-thought (SACoT) framework, which emulates a human-like reasoning process to manipulate the sentiment polarity of aspect terms and proposes a novel approach that leverages LLMs to generate “hard negatives” for ABSA.

A Bayesian Biaffine Variational Graph Convolutional Network (BBV-GCN) for ABSA provides a robust and uncertainty-aware graph reasoning framework for fine-grained sentiment analysis and illustrates how uncertainty-aware weighting can attenuate spurious relations and produce more interpretable aspect-specific latent grap...

Aim/Purpose: This study addresses the challenge of converting large volumes of unstructured online energy discussions into interpretable aspect-level knowledge without manual annotation.
Background: Indonesian public energy discussions provide useful information about issue salience and evaluative judgments. However,...

QMPN, Quality-Aware Memory Prompting Network, is proposed, that stores sample-specific prompts derived from a small support set, retrieves relevant prompting evidence for each query, and uses the retrieved prompts to guide aspect-aware context generation.

An Aspect-guided dual-branch fusion network (ADFN) to enhance sentiment prediction by incorporating external knowledge and integrating coarse and fine information is proposed, which incorporates syntactic dependency information to complement and enrich the textual semantic representations.
