We discuss how collaborative annotations can be exploited to simplify and improve the management of context and resources in the context-aware retrieval field. We apply this approach to our Context Aware Browser, a general purpose solution to Web content perusal by means of mobile devices, based on the user's context. Instead of relying on a pool of experts(More)
This paper discusses the issue of evaluation of context-aware retrieval applications. We begin by describing MoBe, a specific architecture that allows automatic download and execution of context-aware applications on mobile devices. In MoBe, the most relevant applications are selected by matching context and application descriptors. Since several(More)
Due to the appearance and widespread diffusion of new mobile devices (PDAs, smartphones etc.), the traditional notion of computing is quickly fading away, giving birth to new paradigms and to new non-trivial problems. Hence, the scientific community is searching for models, technologies, and ar-chitectures in order to suitably describe and guide the(More)
Due to the appearance and widespread diffusion of new mobile devices (PDAs, smartphones etc.), the traditional notion of computing is quickly fading away, giving birth to new paradigms, where concurrent entities, moving from one location to another, exchange data and cooperate towards a common goal. Hence, the scientific community is searching for models,(More)

As a step further, Mobile 2.0 adapts Web 2.0 technology to mobile users. We intend to study how Web 2.0 and Mobile 2.0 together can(More)
