The purpose of the work presented in this paper is reusing conversational archives. So far we have proposed a method to give structures to conversations by analyzing gaze and utterance data from an interaction corpus, which is a semi-structured set of a large amount of interaction data collected by various sensors. In this paper, we give more detailed structure to conversations by analyzing pos...

A strong interest and need exist in the workplace today to master the skills of conducting difficult conversations. Theories and strategies abound, yet none seem to have found the magic formula with universal appeal and success. If it is such an uncomfortable skill to master is it better to avoid or initiate such conversations with employees? Best practices and evidence-based management guide u...

This thesis presents a concept to achieve non-repudiation for natural language conversations by electronically signing continuous, packet-based, digital voice communication (VoIP). Signing a VoIP-based conversation means to protect the integrity and authenticity of the bidirectional data stream and its temporal sequence which together establish the security context of the communication. The sol...

Although the notion of conversations has been discussed for some time as a way in which to provide an abstract representation of extended agent message exchange, there is still no consensus established concerning how to use these abstractions effectively. This paper describes a layered approach based on coloured Petri Nets that can be used for modelling complex, concurrent conversations among a...

In this paper I examine mixed synchronous and asynchronous text-based conversations that have been carried on in the context of a computer-mediated communication (CMC) system called "Babble", which has been in use by a group of nineteen people for nearly two years. The primary goal is to explore principled ways of analyzing and characterizing conversational activity in such systems using genre ...

ACKNOWLEDGEMENTS I thank my research advisor, Dr. P.A. Vela for his guidance, support, and instilling in me the belief that careful modeling and persistence is key. I thank Dr. Collins for many useful comments during the writing process. I would also like to thank William Mantzel for many useful conversations regarding computer vision, and his friendship. I am grateful to my lab mates, Omar and...
