一种领域知识图谱的本体根类型设计

对象根类型的分类是构建领域知识图谱的基础工作,而现有流行的公共知识库并没有按照领域数据的特点分类,如SUMO的唯一的根类型就是实体,使得领域知识表达存在一定挑战,无法完整地表达如文本、视频图片等知识和关联。领域知识图谱本体的对象根类型除了实体类型,还应增加事件类型、文本类型和多媒体类型,基于4种根类型再扩展到具体分类来表达领域的知识,采用这种方式,可以更好地描述各种典型的领域场景,在实际知识图谱的工具研发中,体现出良好的知识体系和清晰的分类思路。

Object root types design of domain knowledge graph ontology

The classification of the object root types is the basic work of constructing the domain knowledge graph, and the popular public knowledge repository is not classified according to the characteristics of the domain data. For instance, the only root type of SUMO is entity, which brings defects to the domain knowledge expression. Knowledge such as texts, videos and pictures, and their relationships cannot be fully expressed. The object root types of domain knowledge graph ontology should include not only the entity type but also the event type, the text type and the multimedia type. Based on the four root types, types are extended to express the domain knowledge. In this way, various typical domain scenarios can be well described. The proposal has a good knowledge system and clear classification ideas in the development of the actual knowledge graph tools.
