least heuristically) better strategies. Also, the complexity of Algorithm

depends crucially on the
quality of the chosen pair of dominating aggregators. Therefore, there is a need to refine the notion
of dominance by incorporating topological measures of ordering and tightness.
These challenges and many others will enrich the research literature in the years to come.
The area of uncertain schema matching is shaping up into a solid body of research, from theory
to practice. As advances in the field join developments in other, closely related research areas in
data integration, such as entity resolution, we believe the future holds greater automation and better
solutions that will ensure the best possible data management.
