Abstract :
Heterogeneity issues in Web services composition are discussed and classified into heterogeneity between semantic equivalent Web services and heterogeneity between sequent Web services in a process flow, we induce these heterogeneity issues into six types of conflicts, namely semantic conflict, data type conflict, Structure conflict, parameter number conflict, data unit conflict and data precision conflict. Then, an ontology based conflict resolution is designed, including the definition of domain ontology knowledge for business specification, the definition of domain and industry terms ontology knowledge for describing the profile information of Web services and the definition of meta-ontology knowledge for transformation. Furthermore, the implementation issues are presented
