A Survey of Semantics-Based Approaches for Context Reasoning in Ambient Intelligence
نویسندگان
چکیده
A key issue in the study of Ambient Intelligence is reasoning about context. The aim of context reasoning is to deduce new knowledge, based on the available context data. The endmost goal is to make the ambient services more ”intelligent”; closer to the specific needs of their users. The main challenges of this effort derive from the imperfect context information, and the dynamic and heterogeneous nature of the ambient environments. In this paper, we focus on semantics-based approaches for reasoning about context. We describe how each approach addresses the requirements of ambient environments, identify their limitations, and propose possible future research directions.

Employing description logics in Ambient Intelligence for modeling and reasoning about complex situations
Ambient Intelligence systems need to represent information about their environment and recognize relevant situations to perform appropriate actions proactively and autonomously. The context information gathered by these systems comes with imperfections such as incompleteness or incorrectness. These characteristics need to be handled gracefully by the Ambient Intelligence system. Moreover, the r...

Integrating context-aware notification services to ubiquitous computing systems aims at the provision of the right information to the right users, at the right time, in the right place, and on the right device, and constitutes a significant step towards the realization of the Ambient Intelligence vision. In this paper, we present FlexConf, a semantics-based system that supports location-based, ...
متن کاملA Rule-Based Approach to Automatic Service Composition
The incapability to foresee or react to all the events that take place in a specific environment supposes an important handicap for Ambient Intelligence systems, expected to be self-managed, proactive, and goal-driven. Endowing such systems with capabilities to understand and reason about context seems like a promising solution to overcome this hitch. Supported on the service-oriented paradigm,...
متن کاملA Reasoning Framework for Ambient Intelligence
Ambient Intelligence is an emerging discipline that requires the integration of expertise from a multitude of scientific fields. The role of Artificial Intelligence is crucial not only for bringing intelligence to everyday environments, but also for providing the means for the different disciplines to collaborate. In this paper we describe the design of a reasoning framework, applied to an oper...
