On Controlling Fallback Responses for Grounded Dialogue Generation (2022.findings-acl)
Copied to clipboard
| Challenge: | Existing knowledge grounded dialogue frameworks assume that the user intention is always answerable. |
| Approach: | They propose a framework that automatically generates a control token with the generator to bias the succeeding response towards informativeness for answerable contexts and fallback for unanswerable context. |
| Outcome: | The proposed framework incorporates fallback responses to respond to unanswerable contexts in an informative manner while retaining informativeness for answerable context. |
