abstract = {Virtual human characters equipped with natural language dialogue capability have proved useful in many fields like simulation training and interactive games. Generally behind such dialogue managers lies a complex knowledge-rich rule-based system. Building such system involves meticulous annotation of data and hand autoring of rules. In this paper we build a statistical dialogue model from roleplay and wizard of oz dialog corpus with virtually no annotation. We compare these methods with the tra ditional approaches. We have evaluated these systems for perceived appropriateness of response and the results are presented here.},

abstract = {Although the representation of physical environments and behaviors will continue to play an important role in simulation-based training, an emerging challenge is the representation of virtual humans with rich mental models (e.g., including emotions, trust) that interact through conversational as well as physical behaviors. The motivation for such simulations is training soft skills such as leadership, cultural awareness, and negotiation, where the majority of actions are conversational, and the problem solving involves consideration of the emotions, attitudes, and desires of others.The educational power of such simulations can be enhanced by the integration of an intelligent tutoring system to support learners� understanding of the effect of their actions on virtual humans and how they might improve their performance. In this paper, we discuss our efforts to build such virtual humans, along with an accompanying intelligent tutor, for the domain of negotiation and cultural awareness.},

We argue such agent technology has potential, both as a training system to enhance communication skills, and to assess the key factors that influence rapport in face-to-face interactions. We conclude by discussing ways the nonverbal correlates of rapport vary between Arabic and English speakers and discuss the potential of such technology to advance research and training into rapport in cross-cultural settings.},

User-centered design feedback needed to iteratively evolve the system was gathered from returning Iraq War veterans in the USA and from a system in Iraq tested by an Army Combat Stress Control Team.

Our results demonstrate that spectral and contextual features can be used to detect sarcasm as well as a human annotator would, and confirm a long-held claim in the field of psychology — that prosody alone is not sufficient to discern whether a speaker is being sarcastic.},

We consider three classification architectures for selecting the most appropriate out-of-domain responses. We evaluate these architectures and show that they significantly improve the quality of the response selection making the user?s interaction with the virtual character more natural and engaging.},

There are two unifying themes across the presentations. One theme is a commitment to developing computational models useful for simulating the processes that produce the effects and phenomena of interest. The second theme is a commitment to assessing the validity of the models by comparing their performance against empirical human data.},

Virtual humans are intelligent agents with a body, often a human-like graphical body, that interact verbally and non-verbally with human users on a variety of tasks and applications. At a recent meeting on this subject, the above authors participated in a several day discussion on the question of virtual human design. Our working group approached this question from the perspective of interactivity. Specifically, how can one design effective interactive experiences involving a virtual human, and what constraints does this goal place on the form and function of an embodied conversational agent. Our group grappled with several related questions: What ideals should designers aspire to, what sources of theory and data will best lead to this goal and what methodologies can inform and validate the design process? This article summarizes our output and suggests a specific framework, borrowed from interactive media design, as a vehicle for advancing the state of interactive experiences with virtual humans.},

This is often addressed by positing multiple appraisal processes such as fast pattern directed vs. slower deliberative appraisals. In our view, this confuses appraisal with inference. Rather, we argue for a single and automatic appraisal process that operates over a person’s interpretation of their relationship to the environment. Dynamics arise from perceptual and inferential processes operating on this interpretation (including deliberative and reactive processes). We illustrate this perspective through the computational modeling of a naturalistic emotional situation.},

abstract = {Question-answering dialogue systems have found many applications in interactive learning environments. This paper is concerned with one such application for Army leadership training, where trainees input free-text questions that elicit pre-recorded video responses. Since these responses are already crafted before the question is asked, a certain degree of incoherence exists between the question that is asked and the answer that is given. This paper explores the use of short linking dialogues that stand in between the question and its video response to alleviate the problem of incoherence. We describe a set of experiments with human generated linking dialogues that demonstrate their added value. We then describe our implementation of an automated method for utilizing linking dialogues and show that these have better coherence properties than the original system without linking dialogues.},
