The development of speech tools suitable for use in real world environments requires collaboration between computational linguistics and new implementation fields e.g. robotics, and the incorporation of new AI techniques to improve overall system performance. In this paper we present the core development concepts of SAID (Speaking Autonomous Intelligent(More)
The taking of initiative has significance in spoken language dialogue systems and in human-computer interaction. A system that takes no initiative may fail to seize opportunities that are important, but a system that always takes the initiative may not allow the user to take the actions he favours. We have implemented a mixed-initiative planning system that(More)
In 1993, the U.S. Army and U.S. Air Force undertook long-term joint staffing of Landstuhl Regional Medical Center, a 180-bed facility in Germany. With little historical precedence, the Nurse Corps from each service worked diligently to integrate. Initial collaboration suffered because of confusion, ignorance of the other service's capabilities, and(More)
A machine learning approach to interpreting utterances in spoken interfaces is described, where evidence from the utterance and from the dialogue context is combined to estimate a probability distribution over interpretations. The algorithm for the utterance evidence uses nearest-neighbour classification on a set of training examples, while the contextual(More)
A design is presented for a negotiating agent that can construct coherent joint plans with human or artificial agents. In negotiation there is always a trade-off between plan quality and dialogue length. In dynamic conditions and with human partners, length becomes critical. The approach to efficient negotiation is to use an acquaintance model that predicts(More)
