We evaluate the proposed model on three benchmark task-oriented dialog datasets: the Cambridge Restaurant (CamRest676) (Wen et al., 2017b), Stanford In-Car Assistant (In-Car) (Eric et al., 2017) and MultiWOZ (Budzianowski et al., 2018), with 676/3031/10438 dialogs respectively.
multiWOZ is one of the most challenging dataset up-to-date given its multi-domain setting, complex ontology and diverse language styles.
