code for paper 'Reference-Assisted Dialogue Evaluation for Open-Domain Dialogue (ACL2023)'.
Evaluating open-domain dialogue systems is challenging for reasons such as the one-to-many problem, i.e., many appropriate responses other than just the golden response.
As of now, automatic evaluation methods need better consistency with humans, while reliable human evaluation can be time- and cost-intensive.
To this end, we propose the Reference-Assisted Dialogue Evaluation (RADE) approach under the multi-task learning framework, which leverages the pre-created utterance as reference other than the gold response to relief the one-to-many problem.
Specifically, RADE explicitly compares reference and the candidate response to predict their overall scores.
Moreover, an auxiliary response generation task enhances prediction via a shared encoder.
We first collect a pre-train dataset based on existing works. To support RADE, we also extend three datasets with additional rated responses other than just a golden response by human annotation.
All the datasets can be found at ./dataset folder.
