This article presents an adaptive interface agent for SATELIT, a system that integrates Artificial Intelligence methods and hypermedia technology. SATELIT is implemented on the Internet, represented as a set of interactive World Wide Web (WWW) pages with their own functionalities. The SATELIT learning agent was developed for adaptive interface maintenance and pursues either of two main goals, depending on the user’s intentions. First, it is capable of distinguishing the profile of SATELIT experts, whose purpose is to construct a SATELIT application, and it offers a special interface to them. The second aim of SATELIT-Agent is a response to the general hypermedia problem of “getting lost in hypermedia space”. With the help of a learning interface agent, SATELIT will infer an analogue of the user’s search requirements and help him to achieve it, proposing good navigation routes. In this manner SATELIT-Agent functions as an active browser, interactively assisting and guiding the user.
