Most virtual database systems are suitable for environments
in which the set of member information sources is small and stable.
Consequently, present virtual database systems do not scale up very
well. The main reason is the complexity and cost of incorporating new
information sources into the virtual database. In this paper we describe
a system, called Autoplex, which uses machine learning techniques for
automating the discovery of new content for virtual database systems.
Autoplex assumes that several information sources have already been
