Zero-shot Medical Entity Retrieval without Annotation: Learning From Rich Knowledge Graph Semantics (2021.findings-acl)
Copied to clipboard
| Challenge: | Current approaches to medical entity retrieval generalize poorly to unseen sub-specialties . zero-shot retrieval is challenging due to the high degree of ambiguity and variability in medical corpora . |
| Approach: | They propose a set of learning tasks designed to train efficient zero-shot entity retrieval models. |
| Outcome: | The proposed architecture outperforms common zero-shot benchmarks with 7% to 30% higher recall across multiple major medical ontologies. |
Learning to Revise References for Faithful Summarization (2022.findings-emnlp)
Copied to clipboard
| Challenge: | a recent study shows that noisy reference summaries can be detrimental to model performance. |
| Approach: | They propose to selectively re-write unsupported reference sentences to better reflect source data. |
| Outcome: | The proposed method improves reference quality while retaining all data. |
