| Challenge: | Empirical studies of dialogue have shown that people use different kinds of context-dependent linguistic behavior to indicate grounding, including use of fragments, ellipsis and pronominal reference. |
| Approach: | They propose to use open-domain question answering systems as test-bed for task based dialog generation and compare open- and closed-book models to test their hypothesis. |
| Outcome: | The proposed model parrots user input while providing an unfaithful response. |
