Abstract
This paper presents a technique to detect clones in UML class models. Class metrics (number of attributes, number of operations) of a class, class attribute names, root nodes, child nodes and class method names are compared with corresponding metrics, attribute names, root node, child nodes and method names of another class. Based on the number of matched attributes, operations and metrics, a percentage of cloning is calculated. We declare two classes as clones of each other if the matching percentage of the class metrics, class attribute names and class method names is greater than a specific threshold.
