Model-Driven Approach to Constructing UML Sequence Diagram

This paper presents a model-driven approach to transforming the source metamodels of UML Class diagram and Use Case Description to the target metamodel of Sequence diagram, using ATL as the model transformation language. Natural Language Processing is applied for text processing of sentences written in Use Case Description. The resulting metamodel of Sequence diagram is then transformed by Executable jar file for image rendering. The presented method would result in the improvement of software process. Rather than constructing the models from scratch during the different development life cycle stages, applying model transformations could enable the reuse of information that was once modeled, and enhance the consistency among the models representing different views of the system.
