Papers with cross-domain sentiment classification
Cross-Domain Sentiment Classification using Semantic Representation (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing studies on cross-domain sentiment classification ignore the semantic relevance between domains. |
| Approach: | They propose to use Abstract Meaning Representation to help with cross-domain sentiment classification by combining sentence-level AMRs with text-graph interaction models. |
| Outcome: | The proposed model is effective over strong baselines and shows its importance over strong models. |
Identifying Transferable Information Across Domains for Cross-domain Sentiment Classification (P18-1)
Copied to clipboard
| Challenge: | Cross-domain sentiment classification is challenging due to polarity orientation and significance differences . supervised learning algorithms have to be re-trained on every new domain . |
| Approach: | They propose that words that do not change their polarity and significance represent transferable information across domains for cross-domain sentiment classification. |
| Outcome: | The proposed method improves cross-domain sentiment classification performance by identifying polarity-preserving significant words across domains. |
Pivot Based Language Modeling for Improved Neural Domain Adaptation (N18-1)
Copied to clipboard
| Challenge: | Existing work on domain adaptation does not exploit the structure of the input text . PBLM can naturally feed structure aware text classifiers such as LSTM and CNN . |
| Approach: | They propose a model that integrates pivot-based and NN modeling in a structure aware manner. |
| Outcome: | The proposed model can naturally feed structure aware text classifiers such as LSTM and CNN. |
Siamese Network-Based Supervised Topic Modeling (D18-1)
Copied to clipboard
| Challenge: | Label-specific topics are widely used for supporting personality psychology, aspectlevel sentiment analysis, and crossdomain sentiment classification. |
| Approach: | They propose a supervised topic model based on the Siamese network which trades off label-specific word distributions with document-specific label distributions in a uniform framework. |
| Outcome: | The proposed model can trade off label-specific word distributions with document-specific label distributions in a uniform framework. |
