Abstract: The amount of structured information available in Internet sources is rapidly increasing. This information includes commercial databases on product information and information on e-services forming the so-called e-shops. However, the process of using this information has become more complicated, and can sometimes be tedious for users with different goals, interests, levels of expertise, abilities and preferences. This paper deals with the definition of an architectural framework for intelligent, adaptive and personalised navigation within large hypertext Electronic Commerce environments.
