A Simple Architecture for Adaptive Hypertext

We describe a general, flexible architecture based on web standards (W3C Recommendations) where users access data through the mediation of intelligent agents. Architecture is based on simple but effective document and user models, with weighted and semantic tagging of both documents and links. User's profile and preferences affect the agents' behaviour, so that actions can occur on the server as well at the browser side. Profile and preferences accompany the URL reference, avoiding dependence from any central site.
