Abstract: A method of patent retrieval based on ontology was proposed in order to improve the efficiency of patent information retrieval and the integrity of retrieval results.The concept of ontology and the ontology modeling process were discussed.The patent description methods based on ontology and the establishing process of ontology library for patent retrieval were described.A method of relation ontology was proposed,in which the patent application number was taken as the identifier to connect the ontology,the ontology instance and the existing patent information database.Then the establishment of the ontology was expedited and the work of maintenance and renewal of ontology was reduced.A self-organizing approach of relation ontology library was proposed to reduce the input of the domain ontology experts and cause the established ontology to better suit the needs of enterprises.The self-organizing evolution of relation ontology library was described.A concrete patent retrieval process shows that the method of relation ontology is feasible.
