Automatic Translation in Context-Aware Applications

Recently, the literature proposes many approaches to the interoperability of Web data based on the used of formal models. We consider Adaptive Web Applications, in which a relevant requirement is the ability to capture and manipulate context information. Since context data are often heterogeneous, their translations from one representation into another is an important issue that needs to be addressed to facilitate their integration. In this paper we describe a general framework supporting the representation of a large variety of context information and the translation between different formats. Translations are specified as compositions of elementary steps, defined by means of special operations. With these operations, we show how it is possible to process automatically a translation on the models that are provided as source and target.
