指出知识地图作为知识定位、组织和可视化展现的一种方法,是开放关联数据的高效利用和深度挖掘的重要途径。目前,关联数据知识地图的研究仍很薄弱。以研发面向开放关联数据的跨域共享与按需服务为目的,依次研究关联数据知识地图的基本原则、主要特征、体系结构和关键技术。在此基础上,采用语义Web编程技术实现面向DBpedia、Yago、FOAF、Freebase等不同关联数据集的知识地图系统,进一步论证本文的研究工作。
It is pointed out that knowledge map, as a method of locating, organizing and visualizing knowledge, is an important way to open up the efficient use and deep excavation of related data. At present, the research of knowledge map of related data is still weak. With the purpose of researching and developing cross-domain sharing and on-demand services for open related data, the basic principles, main characteristics, architecture and key technologies of knowledge map of related data are studied in turn. Based on this, we use semantic web programming technology to realize the knowledge map system for different related datasets such as DBpedia, Yago, FOAF and Freebase, and further demonstrate the research work of this paper.
