This research studies how that evidence can be formalized and used in spoken dialogue systems. A dialogue system for military training in an immersive virtual environment is implemented and a corpus of human interactions is analyzed to produce a model of evidence of understanding. Patterns in the presentation of this evidence are used to identify the degrees of groundedness that material passes through before becoming sufficiently grounded. Algorithms to identify the evidence of understanding and the degrees of groundedness are implemented and evaluated. Algorithms for dialogue management using this model are implemented in a virtual human in a military questioning domain.
