Multi-Domain Dialogue Acts and Response Co-Generation
Table 1: Overall results on the MultiWOZ 2.0 dataset.
['Dialog Act', 'Model', 'Inform', 'Success', 'BLEU', 'Combined Score']
From the table we can notice that our co-generation model (MarCo) outperforms all the baselines in Inform Rate, Request Success, and especially in combined score which is an overall metric. By comparing the two HDSA models, we can find HDSA derives its main performance from the external BERT, which can also be used to improve our MarCo considerably (MarCo (BERT)). These results confirm the success of MarCo by modeling act prediction as a generation problem and training it jointly with response generation.
