Advances in telecommunication and wireless systems together with the increasing diffusion of portable devices are enabling a pervasive and ubiquitous computing infrastructure for service provisioning, where mobile users expect to access the needed data from ubiquitous attachment points and require context-aware services, i.e., services that can adapt provided results to changing context information, such as variations in user relative position, in user requirements, and in locally available resources. This paper proposes a middleware that supports the intelligent discovery of context-aware services for mobile users, by providing an automatic tool that enable users to specify service queries at a high level of abstraction and a semantics-based matching functionality.
