To enable accessing web information at semantic level, this paper develops a semantic query planning mechanism on XML based web information system with complex ontology mapping technology. It discusses the patterns of complex ontology mappings at first, and then the ontology-based query planning in Mediator-Wrapper based environment with GAV style querying request. The extension of XML query algebra and XML query planning algorithm are discussed in detail.
