Abstract. Web portals provide an efficient gateway to a broad range of Eservices, resources and information. Web portals need to evolve towards being adaptive in nature, so that the ensuing E-services provided by them are dynamically tailored to meet the diverse needs of its users. This paper explores the use of intelligent techniques, in particular constraint satisfaction methods, to develop adaptive E-services that provide customized and factually consistent information to users. We model the generation of customized information content as a constraint satisfaction problem-a solution is derived by (a) satisfying user-model constraints with information document selection constraints; and (b) establishing inter-document consistency when dynamically combining heterogeneous information documents. The work is applied in an E-Healthcare setting leading to the generation of personalized healthcare information.
Abstract. Constraints formalize the dependencies in a physical world in terms of a logical relation among several unknowns. Constraint satisfaction methods allow efficient navigation of large search spaces to find an optimal solution that satisfies given constraints. This paper explores the application of constraint satisfaction methods to personalize generic information content with respect to a user-model. We present a constraint satisfaction based information personalization framework that (a) generates personalized information via the dynamic selection and synthesis of multiple information-snippets; and (b) ensures that the dynamically adapted personalized information is factually consistent. We present four constraint satisfaction methods that cumulatively work to maximize collaboration and minimize conflicts between a set of information-snippets in order to dynamically generate personalized information.
