A heterogeneous multi-agent system for adaptive web applications

A web site presents an intrinsic graph-like spatial structure composed of pages connected by hyperlinks. This structure may represent an environment in which agents related to visitors of the web site are positioned and moved in order to track their navigation. To consider this structure and to keep track of these movements allows the monitoring of the site and of its visitors, in order to support the enhancement of the site itself through forms of adaptivity, carried out by specific interface agents. This paper presents a heterogeneous multiagent system supporting the collection of information related to user's behaviour in a web site by specific situated reactive agents. The acquired information is then exploited by an application supporting the proposal of hyperlinks based on the history of user's movement in the web site environment.
