Transferable Multi-Domain State Generator for Task-Oriented Dialogue Systems
Table 2: The multi-domain DST evaluation on MultiWOZ and its single restaurant domain. TRADE has the highest joint accuracy, which surpasses current state-of-the-art GCE model.
['[EMPTY]', '[BOLD] MultiWOZ  [ITALIC]  [BOLD] Joint', '[BOLD] MultiWOZ  [ITALIC]  [BOLD] Slot', '[BOLD] MultiWOZ (Only Restaurant)  [ITALIC]  [BOLD] Joint', '[BOLD] MultiWOZ (Only Restaurant)  [ITALIC]  [BOLD] Slot']
For comparison with the performance on single-domain, the results on the restaurant domain of MultiWOZ are reported as well. The performance difference between SpanPtr and our model mainly comes from the limitation of index-based copying. For examples, if the true label for the price range slot is cheap, the relevant user utterance describing the restaurant may actually be, for example, economical, inexpensive, or cheaply.
