Evaluating UML Class Diagram Layout based on Architectural Importance

Abstract

The paper presents and assesses a layout scheme for UML class diagrams that takes into account the architectural importance of a class in terms of its stereotype (e.g., boundary, control, entity). The design and running of a user study is described. The results of the study supports the hypothesis that layout based on architectural importance is more helpful in class diagram comprehension compared to layouts focusing primarily on aesthetics and/or abstract graph guidelines
