Simple solutions like manually checking annotations or having a number of staff label every sample are costly and waste effort on samples which can be right. Furthermore, as multiple customers arrive and interact with the DTSM system concurrently, a number of previously unstudied issues arise. Our focus is using car routing heuristics within DTSM to assist retailers manage the availability of time slots in actual time. SA shares data between slots and utterances and only needs a easy construction to predict the supporting span. Moreover, we complement the annotation of supporting span for MultiWOZ 2.1, which is the shortest span in utterances to assist the labeled value. The contrastive loss goals to map slot value contextual representations to the corresponding slot description representations.
