RetroGAN: A Cyclic Post-Specialization System for Improving Out-of-Knowledge and Rare Word Representations (2021.findings-acl)
Copied to clipboard
| Challenge: | Retrofitting is a technique used to move word vectors closer together or further apart in their space to reflect their relationships in a Knowledge Base (KB). |
| Approach: | They propose a system that uses two GANs to learn a one-to-one mapping between concepts and retrofitted counterparts. |
| Outcome: | The proposed system performs well on word-similarity benchmarks and a sentence simplification task. |
Modeling Empathic Similarity in Personal Narratives (2023.emnlp-main)
Copied to clipboard
| Challenge: | EmpathicStories is a dataset of 1,500 personal stories annotated with empathic similarity features and 2,000 pairs of stories annnotated by empathism. |
| Approach: | They propose a task to identify similarity in personal stories based on empathic resonance . they use a dataset of 1,500 personal stories annotated with empathism features . |
| Outcome: | The proposed model outperforms semantic similarity models on correlation and retrieval metrics. |
