Reducing a sequence diagram by dynamic dominance analysis for objects

To understand the behavior of an object-oriented system, visualizing its execution trace as sequence diagrams is effective because the system involves dynamically determined elements. However, sequence diagrams generated from execution traces are too large to understand because the traces include many method calls. This paper proposes a method to vizualize objects and method calls among groups of objects as sequence diagrams by replacing a group of objects with a representative. We conducted a case study as a reduced sequence diagram. As a result, it shows the tool removes about 40 percent of the objects from the execution traces on average.
