In a spoken dialog system, dialog state tracking refers to the task of correctly inferring the
state of the conversation--such as the user's goal--given all of the dialog history up to that …

In spoken dialog systems, statistical state tracking aims to improve robustness to speech
recognition errors by tracking a posterior distribution over hidden dialog states. This paper …

Several studies have addressed the importance of context and users' knowledge and
experience in quantifying the usability and effectiveness of the explanations generated by …

A dialog state tracker is an important component in modern spoken dialog systems. We
present an incremental dialog state tracker, based on LSTM networks. It directly uses …

Dialogue state tracking plays an important role in statistical dialogue management. Domain-
independent rule-based approaches are attractive due to their efficiency, portability and …

We consider the gap between user demands for seamless handling of complex interactions,
and recent advances in dialog state tracking technologies. We propose a new statistical …

Dialogue state tracking (DST) is a process to estimate the distribution of the dialogue states
at each dialogue turn given the interaction history. Although data-driven statistical …

This paper describes the Alex Dialogue Systems Framework (ADSF). The ADSF currently
includes mature components for public telephone network connectivity, voice activity …

This paper presents a sequential labeling approach for tracking the dialog states for the
cases of goal changes in a dialog session. The tracking models are trained using linear …

In this paper, we present an end-to-end bi-model structure for dialogue state tracking, which
can handle the scenarios when the spoken language understanding model with a …
