• Authors: Junfan Chen, Richong Zhang, Yongyi Mao, Jie Xu
• Abstract summary: Dialogue state tracking (DST) is an important part of a spoken dialogue system. Existing DST models either ignore temporal feature dependencies across dialogue turns or fail to explicitly model temporal state dependencies in a dialogue. We propose Temporally Expressive Networks (TEN) to jointly model the two types of temporal dependencies in DST.

• Abstract: Dialogue state tracking (DST) is an important part of a spoken dialogue system. Existing DST models either ignore temporal feature dependencies across dialogue turns or fail to explicitly model temporal state dependencies in a dialogue. In this work, we propose Temporally Expressive Networks (TEN) to jointly model the two types of temporal dependencies in DST. The TEN model utilizes the power of recurrent networks and probabilistic graphical models. Evaluating on standard datasets, TEN is demonstrated to be effective in improving the accuracy of turn-level-state prediction and the state aggregation.

  This paper proposes a method that extracts linguistic knowledge via an unsupervised framework. We then utilize this knowledge to augment BERT's performance and interpretability in Dialogue State Tracking (DST) tasks. We benchmark this framework on various DST tasks and observe a notable improvement in accuracy.

  Dialogue State Tracking (DST) aims to extract users' intentions from the dialogue history.

We propose a Dialogue State Distillation Network (DSDN) to utilize relevant information of previous dialogue states.

  Dialogue state tracking (DST) aims at estimating the current dialogue state given all the preceding conversation. For multi-domain DST, the data sparsity problem is a major obstacle due to increased numbers of state candidates and dialogue lengths. We utilize the previous dialogue state (predicted) and the current dialogue utterance as the input for DST.
