Abstract
A method of query decomposition based on ontology mapping is proposed. By analyzing the domain models and schemas of data sources, a global ontology and local ontology are established, and the mapping between them are generated as well. During the query process, the query is expressed in the form of a tree, and by taking advantage of mapping rules, the query is decomposed into sub-queries.
