CASM: Coherent automated schema matcher

Abstract

Schema matching has been one of the basic tasks in almost every data intensive distributed applications such as enterprize information integration, collaborating web services, web catalogue integration, and schema based point to point database systems and so on. Typical schema matchers perform manually and use a set of matching algorithms with a composition function by using them in an arbitrary manner which results in wasteful computations and needs manual specification for different domains. Recently, there has been some schema matching strategy proposed with partial or full automation. Such a schema matching strategy is OntoMatch. In this paper, we propose an element level automated linguistic based schema matching strategy motivated by the concept of OntoMatch, with more powerful matching algorithms and definite property construction for matcher selection that produces better output. Experimental result is also provided to support the claim of the improvement. © 2013 Springer-Verlag GmbH.
