A user-centric composition model for the Internet of Services

In the modern Internet of Services scenarios, users need to create, share and access contents and services in extremely personalized ways and by means of heterogeneous devices and interaction channels. The most promising architectural solutions to cope with such dynamic and evergrowing scenario adopt a service oriented approach and leverage service composition platforms to flexibly arrange new value added services made up of basic offtheshelf components. Though, current solutions for service composition target rather static scenarios and scarcely support today's dynamic Web, where new services and contents continually become available to satisfy novel user needs and service compositions may become obsolete and need reconfiguration. We propose a novel composition model that aims at being extremely flexible and extensible, yet remaining easily usable by hiding complexity to users.
