While the separation of presentation and application logic is widely practiced in web-based applications today, many do not cleanly separate application and dialog control logic, which leads to inflexible implementations especially when multiple presentation channels shall be served by the same application logic. We therefore present a notation for specifying the complete dialog flow of an appl...

We outline how utterances in dialogs can be interpreted using a partial rst order logic. We exploit the capability of this logic to talk about the truth status of formulae to de ne a notion of coherence between utterances and explain how this coherence relation can serve for the construction of AND/OR trees that represent the segmentation of the dialog. In a BDI model we formalize basic assumpt...

The usability of web applications today often suffers from the page-based medium’s lack of intrinsic support for hierarchical dialog sequences mirroring the parent-child relationships between dialog boxes in window-based user interfaces. For multi-channel applications, an additional challenge lies in reconciling the device-independent business logic with the device-specific interaction patterns...

In this paper, we describe RavenClaw, a plan-based, task-independent dialog management framework. RavenClaw isolates the domain-specific aspects of the dialog control logic from domain-independent conversational skills, and in the process facilitates rapid development of mixed-initiative systems operating in complex, task-oriented domains. System developers can focus exclusively on describing t...

Increasingly, client-server applications are implemented as web-based applications with user interfaces consisting entirely of web pages or equivalent renderings on other presentation channels (e.g. mobile or speech-based devices). However, the page-based medium and the stateless pull communication impose restrictions on the user interface that often manifest themselves in unsatisfactory dialog...

DiaLaw is a dialogical model of legal justification. An important characteristic of the formal and implemented model DiaLaw is that both logic-based arguments and mere convincing statements can be modelled. The support of both structural (logic-based) arguments and procedural arguments (mere convincing statements) is expressed by different levels in the dialog. In this paper so-called dialog tr...

structure of the interface and the appearance of graphical objects be based on conceptual information about domain objects and user actions because, at development time, concrete objects are not available. This paper presents a new approach to model dialog structuring knowledge for interactive infer-faces to realize dialog structuring on the basis of a Description Logic knowledge base.

We present Dialog Moves Markup Language (DMML): an extensible markup language (XML) representation of modality independent communicative acts of automated conversational agents. In our architecture, DMML is the interface to and from conversational dialog managers for user interactions through any channel or modality. The use of a common XML interface language across different channels promotes ...
