Service Oriented Protocols for Human Computation

Human computation and crowdsourcing are increasingly gaining momentum. Many platforms already exist providing basic features for crowdsourcing different types of tasks on the Web. Service Oriented Architectures (SOA) provide the ideal technical framework to support interactions with both Human-Provided Services (HPS) and Software-Based Services (SBS). A unified service-oriented computing approach allows combining the capabilities of humans and software services. Here we discuss the functional and non-functional requirements of service-oriented protocols for human computation. Human interactions in service-oriented systems need to be enabled in a different manner than interactions with software services. We describe the mapping of human interactions onto a service-oriented infrastructure.
