UML Sequence Diagram: Transformation from the Two-Hemisphere Model and Layout

Modeling of the object interaction is one of the core tasks during system analysis and design, because it gives developer an ability to define responsibilities of class objects and to sketch general architecture of software components. In this task an ability of automatic generation of the UML sequence diagram becomes one of the most important activities. The twohemisphere model contains enough information to define operations to perform by classes and therefore is investigated in this paper in the context of the UML sequence diagram generation.
