UML Miner: a tool for mining UML diagrams

Modeling is a key activity in conceptual design and system design, learning and understanding modeling languages such as the Unified Modeling Language (UML) is important. Current UML learning applications and gamification-based alternatives lack guidance for novice modelers regarding possible modeling activities. To overcome this problem, in this demo paper, we present a tool called UML Miner, implemented as a plug-in, that evaluates all UML diagrams realized in the Visual Paradigm environment. UML Miner records all modeling events used in a modeling software project as event logs. By analyzing event logs generated from the use of Visual Paradigm, UML Miner can perform conformance checking to provide useful tips to modelers. These tips are based on the UML model created by highly skilled modelers. In particular, UML Miner can compare different modeling process executions through conformance checking and identify behavioral similarities and differences. The goal of this approach is to improve learner motivation and increase learning outcomes.
