Virtual instructors can be used in several ap- plications, ranging from trainers in simulated worlds to non player characters for virtual games. In this paper we present a novel algorithm for rapidly prototyping virtual in- structors from human-human corpora without manual annotation. Automatically prototyp- ing full-fledged dialogue systems from cor- pora is far from being a reality nowadays. Our algorithm is restricted in that only the virtual instructor can perform speech acts while the user responses are limited to physical actions in the virtual world. We evaluate a virtual in- structor, generated using this algorithm, with human users. We compare our results both with human instructors and rule-based virtual instructors hand-coded for the same task.
