知识图谱人物本体模型设计方法

Knowledge graph person ontology model design method

人物本体在众多领域知识图谱中具有重要的作用,但目前人物本体设计较为简单,难以通用。本文通过人物相关案例构建小型的本体模型,分析其中存在的多元关系问题,结合多元关系的定义介绍多元关系的表示方法。对于在多元关系设计中存在不同设计方案,提出通过将本体模型部分映射为关系数据库,利用关系数据库N泛式原则优化多元关系设计。利用现有的本体模型基础上设计领域本体模型,在兼顾领域问题的同时保证扩展性和通用性,并基于Wikidata中的Human类设计,给出了本文中的人物本体泛式,专门针对地理位置和时间本体进行了优化设计。

Person ontology plays an important role in many domain knowledge graph,but the current person ontology is relatively simple in design and difficult to be universal. This paper constructs a small ontology model through a case,and analyzes the n-ary relation represention issues. For the different design schemes in the n-ary design,it is proposed to optimize the n-ary design by mapping the ontology model into a relational database,and then N-generic principle is uesd for optimizing. The domain ontology model is designed to ensure the extensibility and versatility. Based on the Human class design in Wikidata,the person ontology pattern is given in this paper. Besides this paper proposes a new design method for the geographic location and time ontology.
