面向开放关联数据的知识地图研究

Knowledge Maps for Linked Open Data

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。

As an approach to locate, organize and visualize knowledge, knowledge map provides linked open data with an efficient way of ulilizing and mining it. However, how to construct knowledge maps for linked open data is still an unsettled question for states. Core principles, main characteristics, basic frameworks and key technologies of a knowledge map are discussed respectively in order to give a good support for cross domain sharing and on - denmnd servicing resources in linked open data sets. And then, the study is vali- dated by providing a practical knowledge map, which is build on linked open data,such as DBPedia, Yago, FOAF, FreeBase by se- mantic web technologies.
