Construction safety standards (CSS) have knowledge characteristics, but few studies have introduced knowledge graphs (KG) as a tool into CSS management. In order to improve CSS knowledge management, this paper first analyzed the knowledge structure of 218 standards and obtained three knowledge levels of CSS. Second, a concept layer was designed which consisted of five levels of concepts and eight types of relationships. Third, an entity layer containing 147 entities was constructed via entity identification, attribute extraction and entity extraction. Finally, 177 nodes and 11 types of attributes were collected and the construction of a knowledge graph of construction safety standard (KGCSS) was completed using knowledge storage. Furthermore, we implemented knowledge inference and obtained CSS planning, i.e., the list of standard work plans used to guide the development and revision of CSS. In addition, we conducted CSS knowledge retrieval; a process which supports interrogative input. The construction of KGCSS thus facilitates the analysis, querying, and sharing of safety standards knowledge.
施工安全标准 (CSS) 具有知识特性，但很少有研究将知识图谱 (KG) 作为工具引入 CSS 管理中。为了提高 CSS 知识管理水平，本文首先分析了 218 项标准的知识结构，得出了 CSS 的三个知识层次。其次，设计了一个概念层，该层由五个层次的概念和八种关系类型组成。第三，通过实体识别、属性提取和实体提取，构建了包含 147 个实体的实体层。最后，收集了 177 个节点和 11 种属性，并利用知识存储完成了施工安全标准知识图谱 (KGCSS) 的构建。此外，我们进行了知识推理，并获得了 CSS 规划，即用于指导 CSS 制定和修订的标准工作计划清单。此外，我们还进行了 CSS 知识检索；这是一个支持疑问输入的过程。因此，KGCSS 的构建有利于安全标准知识的分析、查询和共享。
