All our tasks involve a restaurant reservation system, where the goal is to book a table at a restaurant. The first five tasks are generated by a simulation, the last one uses real human-bot dialogs. The data for all tasks is available at http://fb.ai/babi. We also give results on a proprietary dataset extracted from an online restaurant reservation concierge service with anonymized users.The authors would like to thank Martin Raison, Alex Lebrun and Laurent Landowski for their help with the Concierge data.

Q: How large is the Dialog State Tracking Dataset?
A: 1,618 training dialogs, 500 validation dialogs, and 1,117 test dialogs
