煤矿领域知识图谱构建

为有效分析煤矿领域知识之间的联系,将本体技术和知识图谱构建技术相结合,实现煤矿领域核心知识图谱的构建。结合煤矿领域数据特点提出一种基于七步法、METHONTOLOGY法的本体构建方法,并借助本体建模工具Protégé完成对煤矿领域本体的构建;通过对RDF三元组到图数据库结构的映射分析,将煤矿领域本体数据存储于Neo4j图数据库,实现煤矿领域核心知识图谱的初步构建;设计并开发煤矿监测监控原型系统,实现对煤矿知识的存储,有助于保障作业人员的生命安全与设备完整。

CONSTRUCTION OF KNOWLEDGE GRAPH IN COAL MINE DOMAIN

In order to effectively analyze the relationship between knowledge in the coal mine domain,we combined ontology technology and knowledge graph construction technology to realize the construction of the core knowledge graph in the coal mine domain.Based on the data characteristics of coal mine domain,this paper proposed a method of ontology construction based on the seven-step method and the METHONTOLOGY method,and completed the construction of the coal mine domain ontology by means of the ontology modeling tool Protégé.Then,through mapping analysis of the RDF triplet to the graph database structure,the ontology data of coal mine domain were stored in the Neo4j graph database to realize the initial construction of the core knowledge graph in the coal mine domain.We designed and developed the coal mine monitoring prototype system to realize the storage of coal mine knowledge.It helps to ensure the safety of workers and the integrity of equipment.
