全球通信光缆知识图谱构建及应用

Knowledge graph of global communication optical cables:construction and application

利用知识工程相关方法和技术,构建了全球海底光缆知识图谱.知识图谱中,本体包含了8个实体类型、7个实体属性,实例层包含了1949个实体、共计8535个三元组.将所构建知识图谱与DBpedia、Geonames建立了2378个链接,在此基础上,通过SPARQL查询,对海底光缆数据进行了分析.

To obtain full information of submarine cable systems,a method for building knowledge graph is needed.A knowledge graph was built here from open web data,and data in two existing knowledge graphs,DBpedia and Geonames.Eight(8)entity types and 7 properties in the ontology of the built knowledge graph were identified,with 1949 entities and 8535 triples in the knowledge graph,as well as 2378 links between the built knowledge graph and DBpedia,Geonames.SPARQL queries were applied to make in-depth analysis of the built knowledge graph.This knowledge graph will provide important technical support for intelligent analysis of the global submarine cables.
