We have built a prototype Automatic Dialogue Summarizer (ADS) | a real{time system that automatically generates simple summaries of completely spontaneous human{human spoken dialogues without the machine interrupting the natural ow of conversation. Two dialogue participants (client and clerk) discuss conference room reservations (CRR) in Japanese, and the system dynamically updates summaries of...

To enable effective collaborations between humans and cognitive robots, it is important for robots to continuously acquire task knowledge from human partners. To address this issue, we are currently developing a framework that supports task learning through visual demonstration and natural language dialogue. One core component of this framework is the integration of language and vision that is ...

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...

This paper explores the regulatory philosophies underlying the debates on privacy in e-commerce in the European Union and the United States. It offers a framework to grasp these differences and suggests that, in the ultimate, e-commerce players with transatlantic ambitions may need different organizations to deal with the EU and US

dialogue form obliges the reader to consider the discussants' relationships to each other and to the author. In Karhausen's dialogue on Rothman's model of sufficient and component causes (SCC) (e.g. ref. 1, pp.7–17) in this issue of the International Journal of Epidemiology 2 these relationships are complicated by the fact that the participants—Socrates and Epimenide—are historical figures to w...

after the collapse of bipolar system in the world, different views and theories expressed by the scholars and thinkers about the future of the world and international system. one of them is the theory of “ the clash of civilizations” which was propounded in 1993 by the samuel huntington, the director of j.m.olin institute for strategic studies in harvard uni-versity. this theory caused some anx...

This paper presents a novel component for spoken dialogue systems, which adds the functionality of adapting the system’s speech output based on the user’s input. The adaptation in done on the phonetic level for adopting the user’s speech characteristics without changing the system’s own voice. An architecture for a spoken dialogue system is introduced, in which this module creates a direct link...

In the project "Procedural Dialogue Models" being carried on at the University of Bielefeld we have developed an Incremental multilevel parsing formalism to reconstruct task-oriented dialogues. A major difficulty we have had to overcome is that the dialogues are real ones with numerous ungrammatical utterances. The approach we have devised to cope with this problem is reported here. I THE INCRE...

The work in this paper is based on the claim that collaborative dialogue involves taking into account how much information an utterance conveys, in the sense that it thereby shows how it is connected to the linguistic and extra-linguistic context shared by speaker and hearer, by system and human user. I introduce a notion of information enrichment to handle this phenomenon, and discuss informat...
