| Challenge: | Open-domain question answering has exploded in popularity due to the success of dense retrieval models. |
| Approach: | They construct a set of simple, entity-rich questions based on facts from Wikidata and test their models against supervised datasets. |
| Outcome: | The proposed model outperforms sparse retrieval methods on open-domain question answering datasets by a large margin. |
