This paper proposes a probabilistic framework for spoken dialog management using dialog examples. To overcome the complexity problems of the classic partially observable Markov decision processes (POMDPs) based dialog manager, we use a frame-based belief state representation that reduces the complexity of belief update. We also used dialog examples to maintain a reasonable number of system acti...

In the development of spoken dialog systems, domain adaptation and dialog state-dependent language model are usually researched separately. This paper proposes a new approach for domain adaptation augmented by the dialog state-dependence, which means a dialog turn based cache model decaying synchronously with the dialog state change. Through this approach it’s more simple and rapid to adapt a C...

This paper describes a new spoken dialog portal that connects systems produced by the spoken dialog research community and gives them access to real users. We introduce a prototype dialog framework that affords easy integration with various remote dialog agents as well as external knowledge resources. To date, the DialPort portal has successfully connected to two dialog systems and several publ...

Anhand eines Beispiels aus dem Werkunterricht soll in diesem Artikel gezeigt werden, wie inklusive, gleichwertige Bildung im Regelunterricht integriert und umgesetzt werden kann. Durch die räumliche Nähe des Evangelischen Gymnasiums Werkschulheims Wien Erdberg der Hausgemeinschaften Diakonie Gallneukirchen verbringen verschiedene Generationen ihren Alltag unter einem Dach. Die jüngere Generatio...

The integration of utterances in their contexts, by the help of reasoning about the concepts of the domain – organized in a formal ontology and laid down in Description Logics –, enables successful dialogue management for spoken language. We outline our dialogue model and our approach of establishing a formal ontology within the

This paper describes the SmartKom-Home system realized within the SmartKom project. It assists the user by means of a multi-modal dialogue system in the home environment. This involves the control of various devices and the access to services. SmartKom-Home is supposed to serve as a uniform interface to all these devices and services so the user is freed from the necessity to understand which o...

A significant goal in multi-modal virtual agent research is to determine how to vary expressive qualities of a character so that it is perceived in a desired way. The “Big Five” model of personality offers a potential framework for organizing these expressive variations. In this work, we focus on one parameter in this model – extraversion – and demonstrate how both verbal and non-verbal factors...

In natural communication, both speakers and listeners are active most of the time. While a speaker contributes new information, a listener gives feedback by producing unobtrusive (usually short) vocal or non-vocal bodily expressions to indicate whether he/she is able and willing to communicate, perceive, and understand the information, and what emotions and attitudes are triggered by this infor...

Our goal is to develop a flexible dialog system for tutoring mathematical problem solving. Empirical findings in the area of intelligent tutoring show that flexible natural language dialog supports active learning. Therefore, we focus on the development of solutions allowing flexible dialog. However, little is known about the use of natural language in dialog settings in formal domains, such as...
