Composition of e-Services in a multichannel environment requires taking into account the constraints imposed by the context: user profiles, geographical locations, available channels, and usable devices. In this paper, we propose an approach for context-aware composition of e-Services based on an abstract description of both e-Services and context. E-Services are described in terms of functionality and quality of service. The context describes the channels that can be used to access e-Services. The paper proposes adaptation rules as the means to allow the composition and dynamically select e-Service channels according to the constraints posed by available architectures and application-level requirements. Composition and adaptation rules are exemplified on a simple case for emergency management.

Abstract
Composition of e-Services in a multichannel environment requires taking into account the constraints imposed by the context: user profiles, geographical locations, available channels, and usable devices. In this paper, we propose an approach for context-aware composition of e-Services based on an abstract description of both e-Services and context. E-Services are described in terms of functionality and quality of service. The context describes the channels that can be used to access e-Services. The paper proposes adaptation rules as the means to allow the composition and dynamically select e-Service channels according to the constraints posed by available architectures and application-level requirements. Composition and adaptation rules are exemplified on a simple case for emergency management.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
