Query: Using T-Norm Based Uncertainty Calculi in a Naval Situation Assessment
  Application   RUM (Reasoning with Uncertainty Module), is an integrated software tool based
on a KEE, a frame system implemented in an object oriented language. RUM's
architecture is composed of three layers: representation, inference, and
control. The representation layer is based on frame-like data structures that
capture the uncertainty information used in the inference layer and the
uncertainty meta-information used in the control layer. The inference layer
provides a selection of five T-norm based uncertainty calculi with which to
perform the intersection, detachment, union, and pooling of information. The
control layer uses the meta-information to select the appropriate calculus for
each context and to resolve eventual ignorance or conflict in the information.
This layer also provides a context mechanism that allows the system to focus on
the relevant portion of the knowledge base, and an uncertain-belief revision
system that incrementally updates the certainty values of well-formed formulae
(wffs) in an acyclic directed deduction graph. RUM has been tested and
validated in a sequence of experiments in both naval and aerial situation
assessment (SA), consisting of correlating reports and tracks, locating and
classifying platforms, and identifying intents and threats. An example of naval
situation assessment is illustrated. The testbed environment for developing
these experiments has been provided by LOTTA, a symbolic simulator implemented
in Flavors. This simulator maintains time-varying situations in a multi-player
antagonistic game where players must make decisions in light of uncertain and
incomplete data. RUM has been used to assist one of the LOTTA players to
perform the SA task.
