Overview of the Ninth Dialog System Technology Challenge: DSTC9
This is an incremental overview paper for researchers in dialog systems, organizing and benchmarking progress in the field.
The paper introduces the Ninth Dialog System Technology Challenge (DSTC-9), which focuses on applying end-to-end dialog technologies to four distinct tasks in dialog systems, and summarizes the results of submitted systems to highlight state-of-the-art trends.
This paper introduces the Ninth Dialog System Technology Challenge (DSTC-9). This edition of the DSTC focuses on applying end-to-end dialog technologies for four distinct tasks in dialog systems, namely, 1. Task-oriented dialog Modeling with unstructured knowledge access, 2. Multi-domain task-oriented dialog, 3. Interactive evaluation of dialog, and 4. Situated interactive multi-modal dialog. This paper describes the task definition, provided datasets, baselines and evaluation set-up for each track. We also summarize the results of the submitted systems to highlight the overall trends of the state-of-the-art technologies for the tasks.
