In this paper, considering the limitation of keywords-based information retrieval, a framework of Ontology-based semantic information retrieval systems is put forward according to the hybrid Ontology-based integration approaches, and the functions of every module are described. In addition, some key issues are discussed, including query and resource processing, resource searching, and Ontology mapping.
