WebAug 1, 2011 · In a paper published in the 2001 VLDB Conference, we proposed treating generic schema matching as an independent problem. We developed a taxonomy of existing techniques, a new schema matching algorithm, and an approach to comparative evaluation. Since then, the field has grown into a major research topic. WebSchema matching is the problem of finding potential associations between elements (most often attributes or relations) of two schemas. ... Madhavan J., Bernstein P.A., and Rahm …
