Abstract
The current model of the Service Oriented Architecture (SOA) does not directly support possible scenarios for pervasive environments where services can be offered to/from the smart personal devices carried around by different users. Service description technologies such as WSDL provide descriptions of what a service is and what it can do, however with these kinds of descriptions machines still cannot easily interpret different concepts described through technical attributes. If more expressive technologies are used to describe a service, machines become able to identify different components describing a service. In pervasive environments users move around with Personal Agents operating on their portable devices and as mobile devices become more powerful, users are becoming able to host services on their mobile devices too. This project proposes a Service Personalization Architecture that will enable machines to understand the functionality provided by different services and use this knowledge together with the attributes provided by the users' smart devices in order to provide service recommendation, service composition, and service personalisation to the users. © 2010 IEEE.
