Scenario Similarity Map for Visualizing Classified Scenarios

A visually classification method of scenarios using differential information between normal scenarios is presented. Behaviors of normal scenarios belonging to the same problem domain are quite similar. We derive the differential information, named differential scenario, from such normal scenarios and apply the differential scenario to classify scenarios. Our method will be illustrated with examples. This paper describes (1) a language for describing scenarios in which simple action traces are embellished to include typed frames based on a simple case grammar of actions, (2) an introduction of the differential scenario, and (3) a method of visualizing scenario classification named Scenario Similarity Map using the differential scenario.
