                                    ABSTRACT
In a world of global networking, the increasing amount of heterogeneous information,
available through a variety of channels, has made it difficult for users to find the
right information at the right time and at the right level of detail. The knowledge of
the context in which the data are used can support the process of focussing on
currently useful information, keeping noise at bay. In this talk I give an account of
the researches on context-aware information systems which are going on within the
PEDiGREE group at Politecnico di Milano, starting from a foundational framework for the
life-cycle of contextaware systems, in which the system design and management
activities consider context as an orthogonal, first-class citizen. The initial
intuition dates back to the Context-ADDICT project, which proposed a powerful context
modeling tool – known as Context Dimension Tree (CDT) – for context-aware data
tailoring, to represent the admissible contexts and design the accompanying context-
dependent views. The design-time and run-time activities involved in the lifecycle of
context-aware systems provide material for stimulating research, summarized in this
talk.
