Posr: A Comprehensive System for Aggregating and Using Web Services

Recently, the number of public Web services has been constantly increasing. Nevertheless, consuming Web services as an end-user is not straightforward, because creating a suitable user interface for consuming a Web service requires much effort. In this work, we introduce a novel approach where user interface fragments for consuming Web services are generated automatically, and aggregated and customized by end-users to match their preferences. Users can collaboratively improve the auto-generated user interfaces and share them among each other. Our three main sources of Web services are explicit registration, automatic identification and collecting over the Web, as well as extraction and generation from existing Web applications. We validated our approach by implementing it as a comprehensive system coined ldquoPosrrdquo.
