User study of the Bayesian update of dialogue state approach to dialogue management
نویسندگان
چکیده
This paper presents the results of a comparative user evaluation of various approaches to dialogue management. The major contribution is a comparison of traditional systems against a system that uses a Bayesian Update of Dialogue State approach. This approach is based on the Partially Observable Markov Decision Process (POMDP), which has previously been shown to give improved robustness in simulation experiments. Results from this paper show that the benefits demonstrated in simulation experiments are also obtained when testing a live system with real users.

Bayesian update of dialogue state: A POMDP framework for spoken dialogue systems
This paper describes a statistically motivated framework for performing real-time dialogue state updates and policy learning in a spoken dialogue system. The framework is based on the partially observable Markov decision process (POMDP), which provides a well-founded, statistical model of spoken dialogue management. However, exact belief state updates in a POMDP model are computationally intrac...
متن کاملDialogue Simulation and Context Dynamics for Dialogue Management
In this paper we describe DISCUS, a research tool for developing a context model and update algorithm for dialogue management. The model builds on Dynamic Interpretation Theory (DIT), in which dialogue is modelled in terms of dialogue acts operating on the information state of the dialogue participants. On the basis of dialogue act specifications of both system and user utterances, DISCUS perfo...
متن کاملMulti-Party Quantum Dialogue with the Capability to Expand the Number of Users at Runtime
Quantum dialogue is a type of quantum communication in which users can simultaneously send messages to each other. The earliest instances of quantum dialogue protocols faced security problems such as information leakage and were vulnerable to intercept and resend attacks. Therefore, several protocols have been presented that try to solve these defects. Despite these improvements, the quantum di...
متن کاملImplementing the Information-State Update Approach to Dialogue Management in a Slightly Extended SCXML
The W3C has selected Harel statecharts, under the name of SCXML, as the basis for future standards in the area of (multimodal) dialogue systems. The purpose of the present paper is to show that a moderately extended version of SCXML can be used to implement the well-known Information-State Update (ISU) approach to dialogue management. The paper also presents an experimental implementation of Ex...
