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.

基于本体的专利检索技术
通过一个具体的专利信息检索过程说明了关联本体方法的可行性.为了提高专利信息检索的效率和检索结果的完整性,提出一种基于本体的专利检索方法.介绍了本体的基本概念和本体的建模过程,给出了基于本体的专利信息描述和专利信息本体库的建立方法.采用以专利申请号为关联标识,将本体以及本体的实例和现有的专利信息数据库关联起来的关联本体方法,提高了建立本体的速度,减轻了本体的维护和更新工作.为了减少领域本体专家的投入,使得建立的本体更加适合企业的需求,利用一个关联本体库的自组织建立方法,描述了专利关联本体库的自组织进化过程.
