The Context Aware Workflow Execution Framework

The development of self-adapting Web applications based on composite architectures, such as Service Oriented Architectures (SOA), is challenged by the lack of support to the specification of explicit adaptation policies for the context-aware management of the business, interaction and presentation logics. In order to address this limitation, we propose a vertical architecture extending SOA with advanced adaptation features. This article presents the Context Aware Workflow Execution framework (CAWE), which enriches SOA with (a) context-aware workflow management; (b) dialogue management capabilities supporting the adaptation of the interaction with the user, and (c) context-dependent User Interface generation. The article also briefly presents a prototype application developed by exploiting the CAWE framework.
