Abstract: In this paper we present X-Compass, an XML-based agent model for
supporting a user in his Web activities. X-Compass is the result of our attempt
of synthesizing, in a unique context, important guidelines currently
characterizing the research in various Computer Science sectors. Indeed, it
constructs and handles a rather rich, even if light, user profile; this latter
is exploited for supporting the user in an efficient search of information of
his interest; in this way, it behaves as a content-based Recommender System.
Moreover, it is particularly suited for constructing multi-agent systems and,
therefore, for implementing collaborative filtering recommendation techniques.
In addition, since it widely uses XML technology, it is particularly light and
capable of operating on various hardware and software platforms. The adoption
of XML also facilitates the information exchange among X-Compass agents and,
consequently, makes the management and the exploitation of X-Compass based
multi-agent systems easier.
