2017 Lecture Notes in Computer Science  
Unlike the vast majority of the state-of-the-art conversation agents, the proposed agent is constructed around an ontology-based knowledge model that allows for flexible reasoning-driven dialogue planning  ...  We present an intelligent embodied conversation agent with linguistic, social and emotional competence.  ...  To essentially improve on the capacity of a conversational agent to conduct a versatile emotionally and culturally sensitive dialogue, the role of the knowledge model underlying the agent must be reconsidered  ...

2020 Selected Papers of Internet Research, SPIR  
The proliferation of artificially intelligent robots and virtual agents raise practical, technological, and ethical considerations in the emerging area of human-machine communication (HMC) research.  ...  The goal of this panel is to demonstrate the diverse applications of robotics, as well as foster an open-mindset for reconceptualizing humanity in a post-human world.  ...  While a methodology is not presented here, the hyper-memory framework offers a way to deduce what of human memory virtual agents have at their disposal.  ...

Knowledge Representation for Generating Locating Gestures in Route Directions [chapter]

Kristina Striegnitz, Paul Tepper, Andrew Lovett, Justine Cassell
2009 Spatial Language and Dialogue  
A corpus study shows that which perspective is chosen is partly determined by the function of the discourse segment these gestures occur in.  ...  Since locating gestures are so prevalent in direction-giving, in this paper we address the kinds of dialogue information and knowledge representation that is needed to generate them automatically.  ...  This research was supported by a fellowship from the Postdoc-Program of the German Academic Exchange Service (DAAD).  ...

Navigation in Information Spaces: supporting the individual [chapter]

David Benyon, Kristina Höök
1997 Human-Computer Interaction INTERACT '97  
The use of appropriate metaphors is one, virtual reality and 3D interfaces another. A third is to provide adaptive interfaces based on individual differences in users navigational ability.  ...  This paper takes a critical look at the alternatives for assisting users to navigate information spaces and concludes by outlining a research agenda for navigation support.  ...  Such users might prefer to converse with interface agents, to discuss their information needs rather than having to find their own way to the information.  ...
