Adding Chit-Chat to Enhance Task-Oriented Dialogues

NAACL 2021long

Existing dialogue corpora and models are typically designed under two disjoint motives: while task-oriented systems focus on achieving functional goals (e.g., booking hotels), open-domain chatbots aim at making socially engaging conversations. In this work, we propose to integrate both types of syst…

Continual Learning in Task-Oriented Dialogue Systems

EMNLP 2021main

Continual learning in task-oriented dialogue systems allows the system to add new domains and functionalities overtime after deployment, without incurring the high cost of retraining the whole system each time. In this paper, we propose a first-ever continual learning benchmark for task-oriented dia…

Leveraging Slot Descriptions for Zero-Shot Cross-Domain Dialogue StateTracking

NAACL 2021long

Zero-shot cross-domain dialogue state tracking (DST) enables us to handle unseen domains without the expense of collecting in-domain data. In this paper, we propose a slot descriptions enhanced generative approach for zero-shot cross-domain DST. Specifically, our model first encodes a dialogue conte…

Zero-Shot Dialogue State Tracking via Cross-Task Transfer

EMNLP 2021main

Zero-shot transfer learning for dialogue state tracking (DST) enables us to handle a variety of task-oriented dialogue domains without the expense of collecting in-domain data. In this work, we propose to transfer the cross-task knowledge from general question answering (QA) corpora for the zero-sho…
