Papers with Aspect-Term Sentiment Analysis
Supervised Gradual Machine Learning for Aspect-Term Sentiment Analysis (2023.tacl-1)
Copied to clipboard
| Challenge: | Recent work shows that Aspect-Term Sentiment Analysis (ATSA) can be performed by Gradual Machine Learning (GML) but the current unsupervised solution is limited by inaccurate knowledge conveyance. |
| Approach: | They propose a supervised approach which leverages binary polarity relations between instances to enable supervised knowledge conveyance. |
| Outcome: | The proposed approach outperforms pure DNN solutions on real benchmark data. |
DNN-driven Gradual Machine Learning for Aspect-term Sentiment Analysis (2021.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for Aspect-Term Sentiment Analysis (ATSA) use pre-specified lexicons to extract sentiment features. |
| Approach: | They propose a Deep Neural Network-driven approach for Aspect-Term Sentiment Analysis (ATSA) that leverages shared features between labeled and unlabeled instances for knowledge conveyance. |
| Outcome: | The proposed approach consistently achieves state-of-the-art performance on real benchmark data. |
From Graphs to Hypergraphs: Enhancing Aspect-Term Sentiment Analysis via Multi-Level Relational Modeling (2026.acl-srw)
Copied to clipboard
| Challenge: | Existing graph-based approaches to predict sentiment polarity for specific aspect terms rely on predefined pairwise structures to improve expressive capacity. |
| Approach: | They propose a dynamic hypergraph framework that can be used to generate a single instance-specific hypergraph from contextual token representations. |
| Outcome: | The proposed framework improves on Lap14, Rest14, and MAMS . it uses a single instance-specific hypergraph constructed directly from contextual token representations . |
Single-Pass, Depth-Selective Reading for Multi-Aspect Sentiment Analysis (2026.acl-long)
Copied to clipboard
| Challenge: | Existing models re-encode the sentence for each aspect or rely on static use of deep representations, leading to redundant computation and limited adaptivity. |
| Approach: | They propose a single-pass inference framework that encodes each sentence once to construct a reusable, depth-ordered substrate. |
| Outcome: | Experiments show that DABS reduces end-to-end computation by 60% in multi-aspect settings. |
