EXPLORING WEB SERVICES FROM A NETWORK PERSPECTIVE USING MULTI-LEVEL VIEWS

With the spread of service-oriented computing, more and more Web services and service-based applications emerged, and they naturally gave rise to the service ecosystem. The exploration of Web services and the service ecosystem has recently attracted considerable attention from researchers. Since service-based applications such as Mashups are usually developed via composing Web services, the collaboration relation of Web services in Mashups can be used to build Web service networks. To help understanding the characteristics of Web service networks, we propose a three-level view model. With the proposed model, Web service networks can be explored from different-level views such as service-level, tag-level and domain-level, with each level capturing different knowledge of the Web service networks. In the following paper, we firstly describe in detail the three-level view model for Web service networks. Then, based on the model, we present an experimental analysis on real Web service data and report the results. Finally, a visual analysis tool for exploring Web service networks using different-level views is presented.
