Object oriented programming is a fairly complex discipline that requires knowledge ofvarious concepts such as inheritance, encapsulation, and polymorphism. These conceptsare very important for learning more advanced concepts such as design patterns and coderefactoring. Some concepts when applied incorrectly can lead to design flaws, also knownas design smells. Design smells are software structures that may indicate code or designproblems that make the process of software evolution and maintenance complex. Learninghow to avoid these failures and how to refactor them is one of the most important skillsfor becoming a good object-oriented developer. Thus, this work aims to develop a plug-in for the Eclipse development environment to make the process of identifying smells inOO code simpler and faster. Our method has been tested against 4 similar purpose tools(DECOR, JDeodorant, CheckStyle and PMD), running them all in 3 open source projects(JUnit, Log4J and ArgoUML) for the purpose of identifying 4 design smells (InsufficientModularization, Long Method, Long Parameter List and Deficient Encapsulation). Soonafter, we performed a sample analysis in order to demonstrate the expressive power ofusing ontologies by identifying all 14 design smells proposed in this work. The resultsobtained showed that our tool presented 100 % accuracy in all tests, results that wereequal to some tools or were superior to them in others.
