| Challenge: | Retrieval Augment Generation (RAG) has been developed for use in open-domain question answering (ODQA) but it is not optimized for use with other specialized domains such as healthcare and news. |
| Approach: | They propose an extension to RAG that can adapt to a domain-specific knowledge base by updating all components of the external knowledge base during training. |
| Outcome: | The proposed extension can adapt to a domain-specific knowledge base by updating all components of the external knowledge base during training. |
EMO-KNOW: A Large Scale Dataset on Emotion-Cause (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Existing datasets focus on extracting parts of the document that contain the emotion cause and fail to provide more abstractive, generalizable root cause. |
| Approach: | They propose to use 9.8 million cleaned tweets to create a large-scale dataset of emotion causes, derived from 9.8 millions tweets over 15 years. |
| Outcome: | The proposed dataset comprises over 700,000 tweets with corresponding emotion-cause pairs spanning 48 emotion classes, validated by human evaluators. |
