ZhangBing Zhou, Sami Bhiri, Lei Shu, Kaizhu Huang, Laurentiu Vasiliu, Manfred Hauswirth "A Scenario-View Based Approach to Analyze External Behavior of Web Services for Supporting Mediated Service Interactions", Application and Industry Track at IEEE International Conference on Services Computing (SCC 2008), IEEE, 2008.
Web service interactions have triggered the initiative to identify and solve mismatches from a behavioral aspect. Current approaches are limited since they mainly focus on control-flow but largely ignore data-flow. In this paper, we propose an approach to automatically generate scenarios and views for describing external behavior of Web services, i.e. the public process, considering both control-flow and data-flow. We define a scenario as a set of complete execution paths for a public process. Data dependencies are presented as a dependency graph, which is optimized into a minimal dependency graph. Then, a view is generated to describe a scenario for analysis purposes, and external behavior of a Web service is described as a finite set of views. Our approach is very useful for service modelers and users to better understand the external behavior of Web services, to identify and solve mismatches from a behavioral aspect, and thus to facilitate Web service interactions.
