This paper presents and evaluates a behavior-based approach to dialogue management, where a system’s complete dialogue strategy is viewed as the result of running several dialogue behaviors in parallel leading to an emergent coherent and flexible dialogue behavior. The conducted overhearer evaluation of the behaviorbased conversational recommender system CORESONG indicates that the approach can...

In this paper, we outline a data driven approach to mixed initiative dialogue in acoustic user interfaces to databases. We present the knowledge sources that our dialogue planning algorithm needs: the dialogue model, the dialogue history, and the application description. Further, we discuss how the notions of taking, keeping, giving, and relinquishing the turn are reflected in our approach and ...

We describe two major dialogue system segments: first we describe a Dialogue Manager which uses a representation of stereotypical dialogue patterns that we call Dialogue Action Frames and which, we believe, generate strong and novel constraints on later access to incomplete dialogue topics. Secondly, an analysis module that learns to assign dialogue acts from corpora, but on the basis of limite...

Studying dialogue relations as a complex structured output prediction problem, independently of the dialogue outcome, has been the focus of significant research efforts, such as discourse relations [9], rhetorical structure [8, 1] and dialogue act modeling [13]. While these works capture linguisticallymotivated fine-grained dialogue relations, they require considerable effort and linguistic kno...

This paper presents steps towards an incremental dialogue theory in support of functional design of successive generations of spoken language dialogue systems. Dialogue functionality theory departs from a simple task taxonomy and develops a systematic set of concepts or dialogue elements and implementation strategies important to dialogue management. Increasingly complex tasks require the intro...

This paper provides a dialectical characterization of IAR and Brave semantics via argumentation dialogue. We propose a minimal argumentation dialogue system and investigate the relation between its outcome and these semantics. We show that Brave semantics corresponds to a dialogue where the opponent of the Brave-entailed query wins in any dialogue. We show also that IAR semantics corresponds to...

This paper proposes a new framework for a spoken dialogue system based on dialogue examples between human subjects and the Wizard of OZ (WOZ) system. Using this framework and a model of information retrieval dialogue, a spoken dialogue system for retrieving shop information while driving in a car has been designed. The system refers to the dialogue examples to find an example that is suitable f...

This paper presents a spoken dialogue framework that helps users in making decisions. Users often do not have a definite goal or criteria for selecting from a list of alternatives. Thus the system has to bridge this knowledge gap and also provide the users with an appropriate alternative together with the reason for this recommendation through dialogue. We present a dialogue state model for suc...

This paper aims to find errors that lead to dialogue breakdowns in chat-oriented dialogue systems. We collected chat dialogue data, annotated them with dialogue breakdown labels, and collected comments describing the error that led to the breakdown. By mining the comments, we first identified error types. Then, we calculated the correlation between an error type and the degree of dialogue break...

We present in this paper a new problem incorporating the multi-session dialogue of a spoken dialogue system. Instead of engaging a single user in a dialogue, we aim at building a dialogue system that allows engage in a dialogue with multiple successive users. The system can then take an intermediary role to communicate with many users in several discontinuous sessions for reaching a good compro...
