ANALYZING UNIFIED MODELING LANGUAGEUSING CONCEPT MAPPING

摘要

The Unified Modeling Language (UML) is a visual modeling language for object-oriented softwarerndevelopment. Although the Object Management Group (OMG) adopted UML as its standard modelingrnlanguage in 1997, the consensus in the academic community and the industry is that further research is neededrnto evaluate, enhance, extend, and formalize UML. A substantial amount of research has been conducted to thisrnend, but most was based on common sense, informal observation, and intuition. Systematic and empiricalrnstudies to analyze, evaluate, and enhance UML have been lacking. This paper attempts to evaluate and studyrnUML from a cognitive perspective. Specifically, the concept mapping approach will be used to investigate therncognitive process involved in using the UML diagrams. The conceptual maps to be developed on UMLrndiagrams will serve as a cognitive basis for UML evaluation, enhancement, and extension.
