Multi-domain Dialogue State Tracking as Dynamic Knowledge Graph Enhanced Question Answering
Table 6: Model performance on each of the 5 domains.
['[EMPTY]', 'Joint Accuray TRADE', 'Joint Accuray DSTQA w/span', 'Slot Accuracy TRADE', 'Slot Accuracy DSTQA w/span']
We show the performance of DSTQA w/span and TRADE on each single domain. We follow the same procedure as Wu et al. During the training, slots from other domains are ignored. We can see that our model achieves better results on every domain, especially the hotel domain, which has a 11.24% relative improvement. Hotel is the hardest domain as it has the most slots (10 slots) and has the lowest joint accuracy among all domains.
