Professor Helen Meng's team wins ACL DialDoc Challenge 2022

Professor Helen Meng’s team from the Department of Systems Engineering and Engineering Management and Centre for Perceptual and Interactive Intelligence (CPII) (a CUHK-led InnoCentre on AI) won the top prize for their dialogue system at the 2022 DialDoc Workshop.

Organised by the Association for Computational Linguistics (ACL), the 2022 DialDoc Workshop hosted a Shared Task challenge which involved building open-book goal-oriented dialogue systems. Among all the entries, the CPII system topped the leader boards in the two automatic evaluations at the initial stage. Following a further reranking exercise based on manual scores from a fraction (100) of dialogues selected for human evaluators, the system also ranked first and second on the SEEN and UNSEEN leader boards respectively to emerge the best system overall.
