中文摘要：
信息技术，特别是语义网技术的发展激发了用户的信息需求以及信息处理方式的进步。从提升专利研究领域中信息处理效能的角度出发，基于Derwent专利数据库中的专利信息和其中所包涵的语义关系设计Derwent专利本体；实现OWL语言描述的本体模型；研究本体实例的组织方式，将专利信息合理地存储在基于本体模型的逻辑介质中。利用基于本体和语义的知识推理方法，构建专利族引用网络并识别核心专利族。
英文摘要：
The evolution of information technology, especially Semantic Web, has stimulated information requirements and the progress of processing methods. In order to improve the efficiency of information pro- cessing in the field of patent research, this article designed a Derwent patent ontology based on the con- tent of documents and the semantic relationship within them. We implement the patent ontology in OWL form, and discussed the ways of organize the instances in different concepts/classes, which contributed to store the Derwent patent information in logic medium. The research built patent family citation network and try to find the core based on ontology and knowledge inference.
