Integrating human-services using WebComposition/UIX

The Service-Oriented Architectures are often applied to build dynamic Web 2.0 collaboration platforms. As one sees in many crowdsourcing scenarios, not only automated services are involved into such environments - the so called human-provided services are also an integral part of these platforms. It is the users, who produce content, assess products, execute tasks and make decisions. The fact, that the system relies on services "implemented" by people, puts additional requirements on the underlying middleware, especially in the context of user interface aspects, including presentation, interaction and dialog design. In this paper, we describe our approach to extend middleware systems to support human-oriented services. We present the WebComposition/UIX framework, which can be used for automatic generation, configuration and maintenance of user interfaces.
