*Track 4: Robust and Multilingual Automatic Evaluation Metrics for Open-Domain Dialogue Systems - Eleventh Dialog System Technology Challenge (DSTC11.T4)*

*Call for Participation*

*TRACK GOALS AND DETAILS: Two main goals and tasks:*• Task 1: Propose and develop effective Automatic Metrics for evaluation of open-domain multilingual dialogs. • Task 2: Propose and develop Robust Metrics for dialogue systems trained with back translated and paraphrased dialogs in English.

*EXPECTED PROPERTIES OF THE PROPOSED METRICS:*• High correlation with human annotated assessments. • Explainable metrics in terms of the quality of the model-generated responses. • Participants can propose their own metric or optionally improve the baseline evaluation metric deep AM-FM (Zhang et al, 2020).

*TASK 1: METRICS FOR MULTILINGUAL DATA*In this task, the goal for participants is to propose a single metric model effective for the automatic evaluation of multilingual dialogs in English, Spanish and Chinese. The model will provide scores to obtain high correlations with human-annotations. Participants are expected to use pre-trained or fine-tune multilingual models and train them to predict multidimensional quality metrics by using self-supervised techniques.

*TASK 2: ROBUST METRICS*In this task, the goal for participants is to propose robust metrics for automatic evaluation when dealing with English sentences that have been back translated or automatically paraphrased. Here, robustness is understood when using sentences having the same semantic meaning as the original sentence but different wording. The proposed metric model will be evaluated when comparing the scores produced on the original sentences w.r.t. with the scores produced when using the back-translated/paraphrased sentences. Therefore, the expected performance must be on par with the correlations with human-annotations obtained over the original sentences.

*DATASETS:*For training: Up to 18 Human-Human curated multilingual datasets (+3M turns), with turn/dialogue level automatic annotations including QE metrics or toxicity. Dev/Test: Up to 10 Human-Chatbot curated multilingual datasets (+150k turns), with turn/dialogue level human annotations.
