UML tutor for requirements

The united Modeling Language is a collection of text and diagrams that is used throughout the software development process. Tools have been developed to automate diagram rendering, but these require that the user be knowledgeable with the specific diagramming technique. Also, these tools are not capable of correcting logical errors and misconceptions that may be contained in the created model. This poses as a possible risk in the requirements engineering phase, where faulty understanding of requirements may lead to project failure. Use case is the primary modeling technique for requirements analysis. This research aims to develop a tutoring system that will be capable of administering instructor-provided use-case exercises that students will solve. Apart from scenario analysis, students will have to draw the use case diagrams and fill in the corresponding use case descriptions. The system will provide feedback after processing the diagrams and descriptions, and comparing them against the instructor\u27s answers. A bug library was implemented to capture common student errors
