专利本体满足用户对专利信息系统检索的语义需求,但是目前缺乏有效的构建方法,基于WordNet关系数据库的本体构建方法可以根据领域概念直接从关系数据库中获得实体的关系,并扩展原有的领域概念,实现专利领域本体的半自动构建.本文提出了一种基于WordNet关系数据库的本体半自动构建方法,其核心思想是以WordNet关系数据库为主要知识来源,来生成可被本体工具编辑的OWL格式文件,包括两个部分:专利本体数据库半自动构建系统和基于关系数据库本体生成器,本文分析了专利本体数据库半自动构建系统模型,以及专利本体生成与转换流程,并结合实例进行专利本体的构建和应用.%The task of patent Ontology is to meet the semantic demands of patent information searching system , but it wants the eff'ective construction method now. The method of ontology construction based Wordnet relation database can get the relation of entities from relation database based on domain concepts, and expand it to realize the semiautomatic construction. This paper bring forward a kind of method of semiautomatic construction of patent ontology , it' s main idea is that we can take the Wordnet relation database as main knowledge resources, which can be edit hy ontology tools into OWL style files. There is two parts in this method , one is semi-automation construction system of patent ontology, the other is the patent maker based relation database . We analyzed the system model of patent ontology , and the process of build and transformation of patent ontology . We also made a application of patent ontology with the agriculture domain.
