Crowdsourcing has emerged as an important paradigm in human problem solving techniques on the Web. More often than noticed, programs outsource tasks to humans which are difficult to implement in software. In this work we demonstrate the benefit of service-oriented architectures (SOA) applied for enterprise crowdsourcing. Interactions in such environments span human and software services. Crowdsourcing applications typically utilize the capabilities of people in open and dynamic Web-based systems. Dynamically chang-
ing environments, however, demand for flexible interaction models due to the changing availability of people and services. Our main contributions center around the convergence of process flows and dynamic flows in crowdsourcing environments. Here we present a real world example of a human provided service for crowdsourcing in enterprise environments. We demonstrate the application of a human
assisted image processing service in a process-centric flow.
We discuss the foundational building blocks for realizing the design, execution, and adaptation of service-oriented crowdsourcing applications.
