Aspect Sentiment Triplet Extraction with Syntax-Semantics Graph Convolutional Network [PDF]

open access: goldInternational Journal of Computational Intelligence Systems
In the traditional task of aspect sentiment triplet extraction, existing approaches typically focus on either syntactic or semantic features independently, failing to leverage the complementary integration of these two types of information.

A semantically enhanced dual encoder for aspect sentiment triplet extraction [PDF]

open access: greenNeurocomputing, 2023
Aspect sentiment triplet extraction (ASTE) is a crucial subtask of aspect-based sentiment analysis (ABSA) that aims to comprehensively identify sentiment triplets. Previous research has focused on enhancing ASTE through innovative table-filling strategies.

Structural Bias for Aspect Sentiment Triplet Extraction

open access: yesCoRR, 2022
Structural bias has recently been exploited for aspect sentiment triplet extraction (ASTE) and led to improved performance. On the other hand, it is recognized that explicitly incorporating structural bias would have a negative impact on efficiency ...

CONTRASTE: Supervised Contrastive Pre-training With Aspect-based Prompts For Aspect Sentiment Triplet Extraction [PDF]

open access: gold, 2023
Existing works on Aspect Sentiment Triplet Extraction (ASTE) explicitly focus on developing more efficient fine-tuning techniques for the task. Instead, our motivation is to come up with a generic approach that can improve the downstream performances of ...

Semantic and Syntactic Enhanced Aspect Sentiment Triplet Extraction [PDF]

open access: greenFindings of the Association for Computational Linguistics: ACL-IJCNLP 2021, 2021
Aspect Sentiment Triplet Extraction (ASTE) aims to extract triplets from sentences, where each triplet includes an entity, its associated sentiment, and the opinion span explaining the reason for the sentiment.Most existing research addresses this problem in a multi-stage pipeline manner, which neglects the mutual information between such three ...
