The paper mainly discusses the extension of querying on integrated XISs with wrapped ontologies. It discusses the complex ontology mapping patterns with semantically enhanced similarity, such as subsumption mapping, composition mapping and so forth. It also discusses the semantic query mechanism, which primarily extends XML query algebra based on TAX, on the XISs wrapped with local ontologies. Because common XML query languages such as XQuery and XUpdate can be transferred into XML query algebra based on TAX, so the extension is manageable. Complex ontology mapping ensures distributed querying can solve the problem of the inconsistency of semantic and increases the efficiency by refining on the querying and reducing redundancy.
