Domain-specific language for automatic generation of UML models

The majority of flaws found in software originates in the system requirements specification stage. The use of domain-specific languages has shown to be a valuable resource in this part of the process, since they help to establish communication standards, enable automation and bring productivity and quality gains, in spite of their limited vocabulary. This study proposes the implementation of language of use case to automate models (LUCAM), a domain-specific language that allows specification of textual use cases and semi-automated generation of use case diagrams, class diagrams and sequence diagrams through LUCAMTool. To verify the feasibility of the proposed solution, tests were performed in both simulated and real environments so as to comprise a variety of scenarios observed in systems development. The approach assists in the requirement analysis and modelling, minimising existing problems in natural language specification, such as the dependence on the knowledge of specialists, uncertainty, ambiguity and complexity.
