A Rule-based Approach to Content Delivery Adaptation in Web Information Systems

In this paper, we present a rule-based approach supporting the automatic adaptation in Web Information Systems. The approach relies on the general notions of profile and configuration. Special rules are used to specify, in a declarative way, how to build a configuration that satisfies the requirements of adaptation for a profile. The rule evaluation technique guarantees that different contexts and orthogonal requirements of adaptation, possibly not fixed in advance, can be taken into account in the adaptation process.
