Document-level Multi-aspect Sentiment Classification by Jointly Modeling Users, Aspects, and Overall Ratings (C18-1)
Copied to clipboard
| Challenge: | Existing approaches focus on text information, but authors and overall ratings are ignored, both of which are proved to be significant on interpreting the sentiments of different aspects. |
| Approach: | They propose a hierarchical user-aspect rating network model to consider user preference and overall ratings jointly. |
| Outcome: | The proposed model can predict aspects of a product in two real-world datasets. |
An Experimental Study on the Influence of Culture on Cross-Lingual Sentiment Transfer (2026.acl-long)
Copied to clipboard
| Challenge: | Identical linguistic expressions can convey different sentiments across cultural contexts . current multilingual models often reduce language to symbolic representation . cultural misalignment is a structural bottleneck, authors say . |
| Approach: | They conduct an empirical study to quantify the influence of culture on cross-lingual sentiment transfer across 7 common SMLMs and 5 linguistically diverse languages. |
| Outcome: | The proposed model disentangles cultural factors from confounding variables and shows cultural distance is a negative predictor of transfer performance. |
