On Extending Inheritance in UML and Its Errors Evaluation
Subclass/superclass (generalization or inheritance) is very important in real world. There are rich semantic relations in subclass/superclass in addition to generalization in UML.However, UML only represents generalization without representing the other semantic relations in subclass/superclass.In order to describe real world clearly and correctly,generalization in UML is extended into four kinds of subclass/superclass relations and their formalization is presented in the paper. Furthermore, we use the formalization defined in this paper to judge some errors in concept hierarchies and a series of formal decision rules for various errors are proposed.
