Measuring situation assessment performance through the activities of interest score

Situation Awareness involves both the ability to identify and recognize the given activities and in assessing their importance through situation assessment. In this paper we look at a number of metrics that can be used in an information fusion framework to evaluate how well our assessment tools work at discriminating information from data. We begin our discussion by first providing a set of definitions and a reference model. We then summarize previous metrics that we have defined and describe how they can be applied to evaluating situation assessment capabilities. We conclude the paper with an example demonstrating their use and the meaning of the results.
