Abstract. The search of information in heterogeneous systems is always a cru-
cial task. Continuously changing fields of knowledge offer various standards,
methods and technology evolvements to satisfy the users’ queries. In this paper
we present a catalog based system based upon data collection and harmoniza-
tion from distributed fields of knowledge that enables the online search and dis-
covery of information from different thematic regions. The key idea is a multi-
agent platform that enables the connection and interoperability between inde-
pendent agent entities, oriented however at offering manageability and accu-
racy. Users can access data and thematic regions not known to them beforehand
by the use of the automatic multi-agent system. Our approach is ontology-
based, motivated by scenarios of seeking tourist information.
