BioRead: A New Dataset for Biomedical Reading Comprehension (L18-1)
Copied to clipboard
| Challenge: | BioRead is a publicly available cloze-style biomedical machine reading comprehension (MRC) dataset with 16.4 million passage-question instances. |
| Approach: | They propose to build a cloze-style biomedical machine reading comprehension (MRC) dataset with 16.4 million passage-question instances. |
| Outcome: | The proposed method outperforms baselines on bioReadLite and bioASQ, and is currently the best on BioReadLite. |
A Neural Model for Joint Document and Snippet Ranking in Question Answering for Large Document Collections (2021.acl-long)
Copied to clipboard
| Challenge: | Question answering systems typically use pipelines that retrieve documents at finer text granularities. |
| Approach: | They propose an architecture for document and snippet ranking that leverages intuition . they modified a natural questions dataset to test their model . |
| Outcome: | The proposed model outperforms pipelines in document retrieval on biomedical data . the proposed model is competitive with the existing model, despite fewer parameters . |
