As a result, the number of available (heterogeneous) XML data is rapidly increas-ing, and the need for developing high-performance techniques to manage these data isvastly growing. A first step to manage these data is to identify and discover semanticcorrespondences across XML data. The process of identifying semantic correspondencesamong heterogeneous XML data is called XML schema matching.Schema matching in general plays a central role in several shared XML data ap-plications, such as XML data integration, XML data migration, XML data clustering,peer-to-peersystems, etc.
