Table 17: Two generated dialogue examples from our CSTOD model and BORT based on the zero-shot cross-domain setting. (best viewed in color). Gen Dial State and Gen Dial Act denote the generated dialogue state and next dialogue action by BORT. Delexical Resp denotes the generated delexical response by BORT, where specific slot values are replaced by placeholders like _value_price_. Oracle Reference denotes the golden human response.
