Toward the goal of providing automated aides for intelligence analysis, SRI, in cooperation with DARPA and NAVALEX, developed a system called Navint. Navint is an interactive system that aids naval intelligence analysts in estimating the location and activity of surface vessels, based upon a variety of intelligence reports from multiple sources. It focuses on ship-by-ship estimates, using these as the basis for a fleet wide summary. The analyst interacts with the system through a set of display windows. The primary window is a ledger or ``timeline'' that is used to record and organize the daily intelligence data and products for each ship. The mode of interaction is modeled after electronic spread-sheet programs. As the analyst fills in the (electronic) form with the available information, Navint automatically updates related entries. A different view of this same information is provided through ``map'' windows. These display the presumed routes of individual fleet elements overlaid on maps of the appropriate areas. Another display tracks the flow of intelligence information through evidential-reasoning operations (e.g., discounting, fusing, translation, and projection). When a new report is entered by the analyst, a new node is created in this ``analysis'' display to represent the newly acquired information. The application of evidential-reasoning operations spawns new nodes related to preexisting ones. When new nodes are created, labeled links are created between these nodes to trace the heritage of each resulting body of information. Thus, explanations of selected conclusions can be generated by tracing back along these links to find the supporting reports and to determine their relative roles.
