Measuring Performance for Situation Assessment

Abstract

We define a situation estimate as a probability distribution over hypothesized groups, units, sites and activities of interest in a military situation. To be useful to decision makers, there must be a way to evaluate the quality of situation assessments. This paper presents and illustrates an approach to meeting this difficult challenge. A situation assessment integrates low-level sensor reports to produce hypotheses at a level of aggregation of direct interest to a military commander. The elements of a situation assessment include 1) hypotheses about entities of interest and their attributes, 2) association of reports and/or lower level elements with entities of interest, and 3) inferences about the activities of a set of entities of interest. In estimating the quality of a situation assessment, these elements may be scored at any level of granularity from a single vehicle to the entire situation estimate.
