“…In particular, a few works are directed towards context modeling, representation, and effective handling, aspects of particular interest to AMBIT. For instance, [3] proposes to design a context management system which is not application-dependent, [7] proposes an architectural framework for context data management, while [15] reports the result of a study on various context modeling and management approaches. However, most of the approaches in the literature primarily focus on specific aspects such as external user information, and/or do not consider the semantics of the context.…”

-Context-aware application and services proposing potentially useful information to users are more and more widespread; however, their actual usefulness is often limited by the "syntactical" notion of context they adopt. The recently started AMBIT project aims to provide a general software architecture for developing semantic-based context-aware tools in a number of vertical case study applications. In this paper, we focus on the knowledge management foundations we are laying for the Semantic Engine of the AMBIT architecture. The proposed semantic analysis and similarity techniques: (a) exploit the textual information deeply characterizing both users and the information to be retrieved; (b) overcome the limits of syntactic methods by leveraging on the strengths of both classic information retrieval and knowledge-based analysis and classification, ultimately proposing information relevant to the user interests. The experimental evaluation of a preliminary implementation in an actual "cultural territorial enhancement" scenario already shows promising results.

“…Falcarin et al [8] propose a general architectural framework for context data management, which include separate components for context source and context provider modeling. To move closer towards interoperability, they also propose the definition of standard languages for data context representation (ContextML) and access (Context Query Language).…”

The development of ubiquitous services tailored to the needs and expectations of a very large number of potential users (especially mobile users) requires that future applications and systems be aware of the service fruition contexts and possibly of accurate user profiles. The AMBIT research project aims at providing a general model of context as well as a platform that can be exploited to build and deploy different kinds of context-dependent applications and systems. We aim at overcoming the restrictions of the existing approaches, which are mainly due to the limited notion of context they propose (if any). In particular, we stress the fact that current technologies do not accurately consider the notion of context semantics and user profile, which is the main source of the flooding of useless data that overload systems and often users' minds.
