Papers with fine-grained task
Towards Unifying the Label Space for Aspect- and Sentence-based Sentiment Analysis (2022.findings-acl)
Copied to clipboard
| Challenge: | Existing methods to train ABSA model are limited by lack of annotated data . a dual-granularity pseudo labeling approach is proposed to solve this problem . |
| Approach: | They propose a framework for aspect-based sentiment analysis that uses annotated data to train ABSA models. |
| Outcome: | The proposed framework surpasses previous methods on benchmarks. |
Bridge-Based Active Domain Adaptation for Aspect Term Extraction (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods to transfer aspect terms are limited because they require labeled pivot words or expensive computing resources. |
| Approach: | They propose a method that actively supplements transferable knowledge by recognizing syntactic roles as pivots instead of links to pivots. |
| Outcome: | The proposed method significantly outperforms existing methods. |
Does syntax matter? A strong baseline for Aspect-based Sentiment Analysis with RoBERTa (2021.naacl-main)
Copied to clipboard
| Challenge: | Aspect-based sentiment analysis (ABSA) is a fine-grained task in sentiment analysis. |
| Approach: | They compare a model with a dependency parser and a tree from a fine-tuned RoBERTa model to find the polarities for aspects in a sentence. |
| Outcome: | The proposed model outperforms the parser-provided tree on six datasets across four languages. |
C3LPGCN:Integrating Contrastive Learning and Cooperative Learning with Prompt into Graph Convolutional Network for Aspect-based Sentiment Analysis (2024.findings-naacl)
Copied to clipboard
| Challenge: | Recent studies have shown that graph convolutional networks (GCNs) can model syntactic information but incorrect syntaktic structure may introduce additional noise. |
| Approach: | They propose a graph convolutional network which integrates Contrastive Learning and Cooperative Learning with Prompt into GCN to alleviate the noise when modeling syntactic information. |
| Outcome: | The proposed model outperforms state-of-the-art models on three datasets and significantly outperformed existing models. |

| Challenge: | low-resource language corpora in professional domains like medicine hinder cross-lingual domain adaptation of pre-trained large language models. |
| Approach: | They examine how linguistic features affect performance on a Japanese–English medical knowledge benchmark. |
| Outcome: | The proposed model can leverage English-language resources in medical domains while ensuring sufficient coverage of language-specific expressions in a target language. |
