Conclusions
This chapter introduced the notion of a probabilistic mediated schema, and provided
algorithms for constructing them automatically by analyzing the source schemas.
This allows for automatically establishing a fairly advanced starting point for data
integration systems. We believe that the foundation of modeling uncertainty laid out
here will also help pinpoint where human feedback can be most effective in improv-
ing the semantic integration in the system. In the future, we shall consider such
improvement of data integration over time, as well as extensions of our techniques
to deal with multiple-table sources.
