Abstract

Ontology Integration plays a key role in information integration systems, especially in the semi-structured information integration systems. This paper develops an ontology integration mechanism which is based on the complex semantic mapping to avoid the insufficient of simple and direct semantic mapping. It introduces an ontology-based extension to the XML query algebra at first, and discusses the ontology-based query mechanism, which includes ontology integration procedures and XML query rewriting mechanism secondly.
