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. To address this limitation, we propose a vertical architecture extending SOA with advanced adaptation features. This paper presents the Context Aware Workflow Execution framework (CAWE), which enriches SOA with (1) context-aware workflow management; (2) dialogue management capabilities supporting the adaptation of the interaction with the user and (3) context-dependent user interface generation. This paper also briefly presents a prototype application developed by exploiting the CAWE framework.
