Abstract

Web-based Information Systems (WIS) are used for diffusing and processing information over the Internet. Because of the large amounts of information they manage, it is crucial to adapt the delivered information. This can be done by giving users a progressive access to information. For this purpose, we propose to stratify the Information Space of a WIS by decomposing it into personalized sub-Information Spaces. This stratification is described through a Progressive Access Model (PAM) written in UML. The PAM gives WIS users, first, access to some information considered as minimal and essential, and then, allows them to navigate through larger and/or smaller personalized Information Spaces. Together with the PAM, we present a specific query language which allows to query a stratified Information Space. This way, the stratification is taken into account in query expressions, while replies are formatted according to the different levels of detail available in the stratified user’s Information Space.

Keywords
