Ontology Based Semantics Checking for UML Activity Model

Zhixue Wang, Hongyue He, Li Chen and Ying Zhang    

Abstract: UML activity model is mainly used to model the behaviors of software system and the quality of activity model will influence the quality of software system. But because the UML activity model lacks strictly formal semantics, it is difficult to make formal semantics analysis and checking for activity model. An ontology based method of semantics checking for activity model is proposed. The semantics of activity model is divided into static semantics and dynamic semantics. The static semantics is transformed into OWL DL by an algorithm, and the dynamic semantics is described by DL-Safe rules. Then the consistency of UML activity model is analyzed and some model checking rules are defined, which enables model consistency checking by using an ontology reasoning tool.
