Use Case Diagram Similarity Measurement: A New Approach

Building a UML diagram from scratch usually requires a lot of resources of software developer. UML reuse is the solution for speeding up software development process. Previous researches utilized diagram similarity measurement for finding reusable diagrams. Many researchers focus on class and sequence diagrams. This research introduces a new approach for measuring use case diagram similarity. This approach combines structural information and lexical information for measuring the similarity of two diagrams. It used to measure structural similarity, i.e. relationship among and between actors and use cases. It also uses Wordnet, WuPalmer, and Cosine Similarity to measure the lexical information semantically, i.e. and text extracted from actors and use cases. The initial result shows that the semantic and structural information could be used as parameters to measure similarity between two use case diagrams.
