| 摘 要： | 目的/意义]随着知识图谱在互联网领域中的成功应用,使得知识图谱的应用迅速向垂直领域传播与扩散,越来越得到垂直领域的重视。我国各个领域经历了40多年的信息化建设,导致了一大批阻碍信息共享的"信息孤岛",其根本原因是领域没有给予标准化足够的重视。无独有偶,40年后的今天,领域又一次无法回避知识表示中的标准化难题!目前知识图谱构建主要关注点在于知识图谱的构建技术,却很少考虑知识图谱构建中的语义标准化问题。方法/过程]文章在对国内外语义知识标准化相关内容研究的基础上,提出了领域知识图谱构建中应当遵循的五层标准体系模型,该模型融合了国内外领域相关的元数据与本体标准,揭示出知识图谱构建中以元数据标准为核心的重要思想,指导领域选择标准词汇的方法,使得领域所构建的知识图谱实现标准化,从而为知识的共享与互操作奠定基础。结果/结论]在石油术语知识图谱构建过程以该标准体系模型作指导,实现了石油术语知识图谱标准构建,从而验证了标准体系模型的合理性与正确性,文中提出的观点和标准体系模型具有创新性。

Research on Issues of Semantic Standard in Knowledge Graph Construction |

| Abstract: | Purpose/significance]With the successful application of knowledge graph in the field of Internet,the application of knowledge graph has rapidly spread and spread to vertical fields,and more and more attention has been paid to vertical fields.As everyone knows that China’s various fields have experienced more than 40 years of informatization construction,leading to a large number of "information islands" that hinder information sharing.The fundamental reason is that the field has not given enough attention to standardization.Coincidentally,40 years later,the field can no longer avoid the standardization problem in knowledge representation! At present,the main focus of knowledge graph construction lies in the construction technology of knowledge graph,but rarely considers the problem of data semantic standardization in knowledge graph construction.Method/process]Therefore,based on the research on the content of semantic knowledge standardization at home and abroad,this paper proposes a five-layer standard system model that should be followed in the construction of domain knowledge graph.This model combines metadata and ontology standards related to domestic and foreign fields to reveal the important idea with the metadata standard as the core,in the knowledge graph construction,and the method of selecting the standard vocabulary in the field,the standardization of the knowledge graph constructed by the domain,thus laying an important foundation for the sharing and interoperability of knowledge.Result/conclusion]Finally,in the petroleum terminology knowledge graph construction process guided by the standard system model,the standardization construction of petroleum terminology knowledge graph is realized,which verifies the rationality and correctness of the standard system model.The viewpoints and standard system models proposed in the paper have innovative. |
