A message from the challenge organisers
We sincerely appreciate your participation in the Commonsense Persona Grounded Dialogue Challenge 2025! We are excited to announce the top three submissions for each track and would like to congratulate the top-ranked participants on their excellent achievements. Please note that the rankings for Task 2 and Task 3’s Task 2 are based on human evaluation. Therefore, the evaluation process took longer than anticipated, and we appreciate your understanding and patience during this time. We extend our heartfelt thanks to all participants. Please find detailed description of the evaluation process over here.
