We propose the Context-Aware Browser (CAB), a new approach to context-aware Web content perusal by means of mobile devices. The CAB is a Web browser running on mobile devices, exploiting artificial intelligence techniques and mixing several ingredients. The novelty of the proposed approach is threefold. First, our proposal allows a different perspective in the development of Web contents, which should be conceived in a context-dependent way. Our framework makes it possible to develop information and web applications specifically for a given environment, which will become capable to transmit context information, and ad hoc, context-based applications to whom will enter that context. Second, we exploit several informations provided by the surrounding environment and not only the location in order to carry out a more refined search of web contents and applications. Third, the CAB approach involves an innovative two stage retrieval and a filtering process, that minimizes privacy issues.
