Dialogue systems utilise a variety of knowledge sources and models. However, there is a confusion concerning the purposes and contributions of speciic models and the relationships among them. In this paper we present a study of diierent dialogue systems and the knowledge sources and models they use. The models are characterised in terms of what knowledge they contain and the roles of various mo...

For the design of natural language interface systems, a number of models and theories have been developed as well as language processing systems. We propose a model of dialogue systems by a rst-order logical formalization based on meta logics. This model captures various concepts of dialogue systems: the concepts of software systems talking about such as time, actions, conditional and causality...

This study investigated the comparative effects of audio-visually prompted collaborative dialogue on the listening comprehension development of symmetrical, asymmetrical, and asymmetrical teacher-fronted EFL learner groups. Besides, it explored the attitude of the participants of the groups concerning the effectiveness of collaborative dialogue for their listening comprehension improvement. The...

One of the main strategies in Search for Extra Terrestrial Intelligence (SETI) is trying to overhear communications between advanced civilizations. However, there is a (seeming) problem with this approach: advanced civilizations, most probably, save communication expenses by maximally compressing their messages, and the notion of a maximally compressed message is naturally formalized as a messa...

Partially observable Markov decision processes (POMDPs) have gained significant interest in research on spoken dialogue systems, due to among many benefits its ability to naturally model the dialogue strategy selection problem under the unreliability in automated speech recognition. However, the POMDP approaches are essentially model-based, and as a result, the dialogue strategy computed from P...

In this work we study the effectiveness of speaker adaptation for dialogue act recognition in multiparty meetings. First, we analyze idiosyncracy in dialogue verbal acts by qualitatively studying the differences and conflicts among speakers and by quantitively comparing speaker-specific models. Based on these observations, we propose a new approach for dialogue act recognition based on reweight...

This demo paper describes our Artificial Intelligent Dialogue Agent (AIDA), a dialogue management and orchestration platform under development at the Institute for Infocomm Research. Among other features, it integrates different human-computer interaction engines across multiple domains and communication styles such as command, question answering, task-oriented dialogue and chat-oriented dialog...

studying the dialogue properties in rigveda and avesta indicates a type of dialogue called “philosophical dialogue” that is the synonym of “nonviolence”. according to the author, the initial root of forming the dramatic dialogue is based on philosophical dialogue, i.e. a type of fluidity and flow of meaning between two sides of the relation and by such relation it will be made a new concept. th...

This paper summarizes the latest, final version of ISO standard 24617-2 “Semantic annotation framework, Part 2: Dialogue acts”. Compared to the preliminary version ISO DIS 24617-2:2010, described in Bunt et al. (2010), the final version additionally includes concepts for annotating rhetorical relations between dialogue units, defines a full-blown compositional semantics for the Dialogue Act Mar...
