Learn to Focus: Hierarchical Dynamic Copy Network for Dialogue State Tracking [article]

Linhao Zhang, Houfeng Wang
2021 arXiv   pre-print
In this paper, we propose a Hierarchical Dynamic Copy Network (HDCN) to facilitate focusing on the most informative turn, making it easier to extract slot values from the dialogue context.  ...  Recently, researchers have explored using the encoder-decoder framework to tackle dialogue state tracking (DST), which is a key component of task-oriented dialogue systems.  ...  To this end, we propose a Hierarchical Dynamic Copy Network (HDCN) to facilitate focusing on the most informative turns, making it easier to copy slot values from the dialogue context.  ...

Learning to Memorize in Neural Task-Oriented Dialogue Systems [article]

Chien-Sheng Wu
2019 arXiv   pre-print
In this thesis, we leverage the neural copy mechanism and memory-augmented neural networks (MANNs) to address existing challenge of neural task-oriented dialogue learning.  ...  We also evaluate unseen domain dialogue state tracking and show that TRADE enables zero-shot dialogue state tracking and can adapt to new few-shot domains without forgetting the previous domains.  ...  dynamic query memory network, with recorded delexicalization copying for end-to-end retrievalbased dialogue learning.  ...
