Semantic Query Transformation

An Approach to Achieve Semantic Interoperability in Homogeneous Application Domains
  • Narasimha Bolloju

Abstract

Semantic interoperability is concerned with the cooperation among information systems by providing transparent information exchange independent of semantic heterogeneity. Information systems of similar application domains exhibit more semantic problems compared to those of different domains due to the overlap in the underlying real-world concepts. We shall call the former category of application domains as the homogenous application domains. Approaches to handle semantic heterogeneity have been mostly based on either schema integration (common global schema) or schema mapping (multidatabase or federated systems). This paper presents an alternative approach to achieve semantic interoperability based on semantic query transformation. This approach assumes the availability of an object-oriented model based schema and a domain knowledge of the local context and an object-oriented model based schema of the target context. An informal description of the transformation process is presented with an illustrative example.
