Papers with cross-lingual sentiment analysis
Learning Bilingual Sentiment-Specific Word Embeddings without Cross-lingual Supervision (N19-1)
Copied to clipboard
| Challenge: | Unsupervised BWE methods are evaluated on word translation or word similarity tasks. |
| Approach: | They propose a method that learns sentiment-specific word representations for two languages in a common space without cross-lingual supervision. |
| Outcome: | The proposed method outperforms previous unsupervised BWE methods and even supervised Bwe methods on three language pairs for cross-lingual sentiment analysis. |

Mengzhou Xia, Guoqing Zheng, Subhabrata Mukherjee, Milad Shokouhi, Graham Neubig, Ahmed Hassan Awadallah
| Challenge: | Recent work shows that multilingual representations are disjointed across languages, bringing additional challenges for transfer onto extremely low-resource languages. |
| Approach: | They propose a meta-learning based framework that learns to transform representations judiciously from auxiliary languages to a target one and brings their representation spaces closer for effective transfer. |
| Outcome: | The proposed framework learns to transform representations from auxiliary languages to a target language and brings their representation spaces closer for effective transfer. |
Curriculum Knowledge Distillation for Emoji-supervised Cross-lingual Sentiment Analysis (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing sentiment analysis models do not have sufficient sentiment corpus to detect sentiment in low-resource languages. |
| Approach: | They propose a cross-lingual sentiment analysis approach to transfer sentiment knowledge across languages . they use emojis to bridge the source and target languages to find the sentiment . |
| Outcome: | The proposed approach bridges the source and target languages using emojis . it can learn delicate sentiment knowledge, avoiding cross-lingual gaps . |
Projecting Embeddings for Domain Adaption: Joint Modeling of Sentiment Analysis in Diverse Domains (C18-1)
Copied to clipboard
| Challenge: | Existing domain adaptation methods for sentiment analysis are sensitive to domain differences, resulting in classifiers that perform poorly on new domains. |
| Approach: | They propose a domain adaptation problem as an embedding projection task using two mono-domain embeddable spaces and a bi-domain space to project across domains and predict sentiment. |
| Outcome: | The proposed model performs better on domains similar to state-of-the-art methods while requiring longer training times. |
Cross-Cultural Similarity Features for Cross-Lingual Transfer Learning of Pragmatically Motivated Tasks (2021.eacl-main)
Copied to clipboard
| Challenge: | a large amount of work on cross-lingual transfer learning focused on typological and genealogical similarities between languages. |
| Approach: | They propose three features that capture cross-cultural similarities that manifest in linguistic patterns and quantify distinct aspects of language pragmatics. |
| Outcome: | The proposed features capture cross-cultural similarities manifest in linguistic patterns and quantify aspects of language pragmatics. |
