A context-aware mobile mash-up platform for ubiquitous web

Context-aware systems allow users to access services and multimedia data according to their current context (location, identity, preferences). We deem that applying Web 2.0 and ubiquitous Web concepts as guiding principles to design middleware infrastructure may ease the development and deployment of context-aware systems and, so, result in a wider adoption of intelligent environments. Our work combines social context-aware annotation of objects and spatial regions with sentient mobile devices in order to enable advanced context-aware data and service discovery, filtering and consumption for both indoor and outdoor environments.
