Transforming passive users into service providers via semantic enhanced service oriented architecture

The omnipresence of mobile devices has changed the users behaviour. The content present in the Web is created by simple users. Nevertheless, this content is in the cloud and not shared directly from users. This behaviour is a passive one. In this paper, we propose a service architecture which transforms passive users into service providers. This role is acquired in a specific ambient where users share services with each other. Thanks to this collaboration, people can find adequate solutions to a specific problem. A university campus scenario illustrates the functionalities of the service architecture. The proposed solution has a layered structure that integrates Web services with a semantic modelling of the context. This model describes a specific vocabulary to be used when creating or requesting services. The resulting services are organised in groups according to selected criteria.
