Managing Dynamic Context to Enable User-Driven Web Integration in the Personal Web

ThePersonal Webis the people-centric instantiation of the Smart Internet where information systems, services and web content are articulated by users according to their matters of concern. To realize the vision of the Personal Web, the Smart Internet requires infrastructure to support the user in the integration of personal data and the composition of personal services within a highly dynamic context that constitutes the user’sPersonal Web Sphere. To address these requirements, we propose a user-driven context management framework, built on the top of the basic enabling infrastructure of the Personal Web, to support users in the run-time modification ofpersonal context models. The core of our proposal is the management of monitoring concerns by implementing feedback loops, where the user acts as the planner of the controller to adapt the monitoring strategy by means of using web interactions to modify the personal context models. These context models, deployed at three di!erent levels of abstraction, represent monitoring concerns by defining abstract types of contextual entities, the relationships among them and the interactions that the user can instantiate to drive web integration.
