Abstract:

In software reuse, the design model reuse has received more attention. UML class diagram is widely used in software design and the reuse of UML class diagram has become the focus of software design reuse research. As the number of reusable UML class diagrams increases, the classification becomes a fundamental task. A novel two-level classification of UML class diagrams is proposed based on semantics. The semantic similarity measure between UML class diagrams is proposed, a maximum capture algorithm is proposed to obtain center class diagrams to identify the characteristics of each category, and a novel ensemble classifier E-KNN is built based on improved KNN algorithm. The effectiveness of the proposed classifier is verified from classification quality and efficiency.

Key words: UML class diagram, classification, semantic similarity, center class diagram, classifier
