Goal-Oriented Multi-Task BERT-Based Dialogue State Tracker

Understand

Dialogue State Tracking (DST) is a core component of virtual assistants such as Alexa or Siri.

• To accomplish various tasks, these assistants need to support an increasing number of services and APIs.
• The Schema-Guided State Tracking track of the 8th Dialogue System Technology Challenge highlighted the DST problem for unseen services.
• The organizers introduced the Schema-Guided Dialogue (SGD) dataset with multi-domain conversations and released a zero-shot dialogue state tracking model.
