Deriving Global Conceptual Views from Multiple Information Sources

Conceptual modeling plays a relevant role in the development of information systems and software applications. In the last two decades large sets of conceptual schemas have been produced in most private and public organizations, and in recent times the need of analyzing and classifying this large amount of information resources is becoming increasingly important. In the paper, we present a set of methods and tools for the definition of global views of information from multiple and heterogeneous sources, to support querying facilities and navigation among them.
