Enhancing the Capabilities of Attribute Correspondences

Abstract

In the process of schema matching, attribute correspondence is the association of attributes in different schemas. Increased importance of attribute correspondences led to new research attempts that were devoted to improve attribute correspondences by extending their capabilities. In this chapter, we describe recent advances in the schema matching literature that attempt to enhance the capabilities of attribute correspondences. We discuss contextual schema matching as a method for introducing conditional correspondences, based on context. The use of semantic matching is proposed to extend attribute correspondences to results in an ontological relationship. Finally, probabilistic schema matching generates multiple possible models, modeling uncertainty about which one is correct by using probability theory.
