Multiview Similarity Assessment Technique of UML Diagrams

Software system development has been beset by consistency problem since its infancy. This problem is still greater during the software design stage, and are greater still in UML diagrams. This is principally caused because of the existence of multiple views among UML diagrams. The main issue that arise when assessing the similarity of UML diagrams from multiple views is how consistency can be maintained across different views during the comparison. Previous works have failed to address this issue. They only compare one type of diagram in one stage and another type of diagram in another stage, this manner of similarity assessment lead to incorrect similarity scores, thereby creating inconsistencies in the information conveyed by the UML artifacts during software reuse. This paper presents Multiview similarity assessment technique, in which the similarity of UML diagrams is computed from structural and behavioral views of software systems.
