Multi-domain Task-oriented Dialog Challenge II at DSTC9

The paper provides an overview of the “Multi-Domain Task Completion Dialog Challenge II” track at the 9th Dialog System Technology Challenge (DSTC9). Two tasks are introduced in this track. One is end-to-end multi-domain task completion, which focuses on building end-to-end task completion dialog systems. The other is cross-lingual dialog state tracking, which seeks to build a tracker for the target language using the source language resources. We describe the task settings, baselines, evaluation methods, and submission results for both tasks.
