摘　　要：目前常规的基建工程知识库主要采用自下而上的方式对工程数据进行存储,由于对基建工程知识数据的融合程度较低,导致知识库的数据调度性能不佳。对此,提出基于语义概率图与关联规则的基建工程知识库构建方法。将电网基建工程数据转换为事件数据,对其进行关联分析,并结合关联分析结果以及语义概率图对基建工程知识图谱实体进行构建。通过计算文本词汇相似度,实现基建工程知识数据的深度融合,并对知识图谱进行复用,结合知识概念以及属性的抽取结果,实现知识库的构建。在实验中,对提出的知识库进行数据抽取性能的检验。经实验结果表明,采用所提方法构建的基建工程知识库,单位时间内可调度工程资源数据量较高,具备较为理想的数据调度性能。The current conventional infrastructure engineering knowledge base mainly adopts a bottom-up approach to store en-gineering data,which leads to poor data scheduling performance due to the low degree of integration of infrastructure engineer-ing knowledge data.In this regard,the method of constructing infrastructure engineering knowledge base based on semantic probability graph and association rule is proposed.The power grid infrastructure engineering data are converted into event da-ta,association analysis is performed on the data and the infrastructure engineering knowledge graph entity is constructed by combining the association analysis results and semantic probability graph.The deep fusion of infrastructure engineering knowl-edge data is realized by calculating the text lexical similarity,the knowledge graph is reused,and the knowledge base is con-structed by combining the extraction results of knowledge concepts and attributes.In the experiment,the data extraction per-formance of the proposed knowledge base is examined.The experimental results show that the infrastructure engineering knowledge base constructed by the proposed method has a high amount of schedulable engineering resource data per unit time and has a more desirable data scheduling performance.
