Abstract Aiming at some problems in traditional information retrieval under the present network information environment, the paper puts forward patent information retrieval model based on domain Ontology, and makes in-depth study on the process and technical implementation of user retrieval request disposal, Ontology construction, Ontology visualization and semantic expansion, retrieval and storage. A prototype patent information retrieval system is also implemented. Via a series of retrieval effects tests, the model can ensure accuracy of information retrieval and greatly improve the comprehensiveness of information retrieval.
