This paper presents a model for simulating cultural differences in the conversational behavior of virtual agents. The model provides parameters for differences in proxemics, gaze and overlap in turn taking. We present a review of literature on these factors and show results of a study where native speakers of North American English, Mexican Spanish and… (More)
We present Hassan, a virtual human who engages in Tactical Questioning dialogues. We describe the tactical questioning domain, the motivation for this character, the specific architecture and present brief examples and an evaluation.
We present a new approach for rapidly developing dialogue capabilities for virtual humans. Starting from domain specification , an integrated authoring interface automatically generates dialogue acts with all possible contents. These dialogue acts are linked to example utterances in order to provide training data for natural language understanding and… (More)
In this paper we contrast three architectures for natural language questioning characters. We contrast the relative costs and benefits of each approach in building characters for tactical questioning. The first architecture works purely at the textual level, using cross-language information retrieval techniques to learn the best output for any input from a… (More)
Trust is a crucial quality in the development of individuals and societies and empathy plays a key role in the formation of trust. Trust and empathy have growing importance in studies of negotiation. However, empathy can be rejected which complicates its role in negotiation. This paper presents a linguistic analysis of empathy by focusing on rejection of… (More)
The purpose of this paper is to develop a theoretical model of mitigation by integrating cognitive and discourse approaches to appraisal and coping. Mitigation involves strategic , emotional, linguistic, and Theory of Mind processes on different levels of consciousness. We emphasize that discourse analysis can assist our understanding of these processes.
Different cultures have different business communication behaviors. With the acceleration of globalization in business, understanding and accommodating activities in inter-cultural contexts become more regular. Do people from different cultures keep the same style of communication in mono-cultural and intercultural negotiations? Do their behaviors change in… (More)
This paper reviews nine available transcription and annotation tools, considering in particular the special difficulties arising from transcribing and annotating multi-party, multi-modal dialogue. Tools are evaluated as to the ability to support the user's annotation scheme, ability to visualize the form of the data, compatibility with other tools,… (More)
This paper describes the development of a multi-modal corpus based on multi-party multi-task driven common goal oriented spoken language interaction. The data consists of approximately 10 hours of audio human simulation radio data and nearly 5 hours of video and audio face-to-face sessions between human trainees and virtual agents.
