WebUnderstanding the schema matching problem. Authors: Alsayed Algergawy. Institute for Technical and Business Information Systems, Department of Computer Science, Otto-von-Guericke University, Magdeburg, Germany ... WebSome of our innovations are the integrated use of linguistic and structural matching, context-dependent matching of shared types, and a bias toward leaf structure where much of the schema content resides. After describing our algorithm, we present experimental results that compare Cupid to two other schema matching systems.
