Transition-based Opinion Generation for Aspect-based Sentiment Analysis (2024.findings-acl)
Copied to clipboard
| Challenge: | Existing approaches to aspect-based sentiment analysis often overlook the importance of explicitly modeling structure among sentiment elements. |
| Approach: | They propose to integrate general pre-trained sequence-to-sequence language models with a structure-aware transition-based approach to model sentiment structure. |
| Outcome: | The proposed model improves the state-of-the-art performance on several benchmark datasets. |
Structure-aware Fine-tuning of Sequence-to-sequence Transformers for Transition-based AMR Parsing (2021.emnlp-main)
Copied to clipboard
| Challenge: | Recent work shows that pre-trained sequence-to-sequence Transformer models are effective in predicting linearized Abstract Meaning Representation graphs. |
| Approach: | They propose a structure-aware transition-based approach to AMR parsing that integrates general pre-trained sequence-to-sequence language models with a structured transition set. |
| Outcome: | The proposed approach retains the desirable properties of previous approaches while reaching the new parsing state of the art for AMR 2.0. |
QASem Parsing: Text-to-text Modeling of QA-based Semantics (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing work suggests the appeals of incorporating explicit semantic representations into NLP . semi-structured natural language structures provide an intermediate meaning-capturing representation . |
| Approach: | They propose a semi-structured natural-language representation of textual information . they examine input and output linearization strategies and multitask learning . |
| Outcome: | The proposed model is based on pre-trained sequence-to-sequence language models . it is easy to use and can be used for downstream tasks that benefit from it . |
