Neighborhood Network for Aspect-Based Sentiment Analysis

open access: yes, 2022
Different aspects of a sentence may contain different sentiments, and sentiment descriptors for a given aspect exist in different places in the sentence, making it difficult to determine its sentiment polarity. Aiming at the above problems, a neighborhood network (Nenet) for aspect-based sentiment analysis is proposed.

Opinion Tree Parsing for Aspect-based Sentiment Analysis

open access: yesFindings of the Association for Computational Linguistics: ACL 2023, 2023
Extracting sentiment elements using pre-trained generative models has recently led to large improvements in aspect-based sentiment analysis benchmarks. However, these models always need large-scale computing resources, and they also ignore explicit modeling of structure between sentiment elements. To address these challenges, we propose an opinion tree
