Enhancing user-service interaction through a global user-centric approach to soa

Considered as enablers of seamless application-to-application integration both within company boundaries and on a global scale, Web Services-based SOAs have tra-ditionally focused on automating service-to-service collab-oration. However, they have neverfeatured a "face " to hu-man users. This gap between human users and services still prevenís enterpnses from realizing how innovations at the SOA front-end help to make people more productive. And, ultimately, it hinders the emergence of a real Web of Ser-vices driven by a global, user-centric SOA. In this paper, we revisit the notion of SOA and analyze its major short-comings with regard to the emergence of a Web of Services enhancing user-service interaction and increased service usability. We then elabórate on novel, currently emerging technologies that facilítate the establishment of the global mesh of interoperable user-centric services. A novel plat-form architecture is presented thatbuilds on all the key tech-nical enablers.
