Providing top-K alternative schema matchings with Onto Matcher

Abstract

Uncertainty management at the core of data integration was motivated by new approaches to data management, such as dataspaces [2] and the use of fullyautomatic schema matching takes an increasingly prominent role in this field. Recent works suggested the use, in parallel, of several alternative schema matching, as an uncertainty management tool [3,1]. We offer in this work OntoMatcher, an extension of the OntoBuilder [4] schema matching tool to support the management of multiple (top-K) schema matching alternatives. © 2008 Springer Berlin Heidelberg.
