Evaluating Token-Level and Passage-Level Dense Retrieval Models for Math Information Retrieval (2022.findings-emnlp)
Copied to clipboard
| Challenge: | a recent study has shown that dense retrieval methods are suboptimal for capturing contextual similarities in complex data. |
| Approach: | They propose to combine a structure search method and efficient bi-encoder dense retrieval models to capture contextual similarities. |
| Outcome: | The proposed model improves on token-level and passage-level dense retrieval tasks. |
