t5-large-coqr-canard
This model is a fine-tuned version of t5-large on the CANARD dataset. It achieves the following results on the test set:
- Loss: 0.3064
- Bleu: 77.1979
- Generation Length: 9.576
Model description
CANARD dataset rewrites the original questions in conversations to make them context-independent (understandable w/o context). On the contrary, this model is trained to rewrite context-independent questions to conversational questions, aiming to create fluent dialog with anaphora and ellipsis.
Input:
Rewrite the question according to the given context to make the dialog fluent using anaphora and ellipsis.
question: How did people respond to Superstar Billy Graham's return?
context: Superstar Billy Graham
Return to WWWF (1977-1981)
Why did he return to the WWWF?
an agreement with promoter Vincent J. McMahon (Senior
What was his agreement with McMahon?
I don't know.
Target:
How did people respond to his return?
