【 摘 要 】

Web service interactions have triggered the initiative to iden-tify and solve mismatches from a behavioral aspect. However, current approaches are limited because they mainly focus on control-ow and largely ignore data-ow. Such ignorance may cause unexpected or wrong, even unsupported interactions. To address these problems, we propose a scenario-view based approach, which considers both control-ow and data-ow, to support Web service interactions. We rstly generate sce- narios and views for describing a public process. Then, the degree of compatibility of two public processes is computed based on pairwise compatibility of their views. A process mediator is generated for com- patible public processes, and thus an interaction is carried out despite mismatches exist among them. This novel approach will benet service modelers and users not only for a better understanding of public pro- cesses, but also for improved capability to identify and solve mismatches, which will further facilitate Web service interactions.
