Integration of multiple heterogeneous data sources continues to be a critical problem for many application domains and a challenge for researchers world-wide. With the increasing popularity of the XML model and the proliferation of XML documents on-line, automated matching of XML documents and databases has become a critical problem. In this paper, the authors present a hybrid schema match algorithm - QMatch - that provides a unique framework for combining existing structural and linguistic algorithms while exploiting additional information inherent in XML documents such as the order of XML elements to provide improved levels of matching between two given XML Schemas.
