关联数据及DBpedia实例分析

Linked Data and DBpedia Case Analysis

基于关联数据的基本原则和发布方法,分析介绍DBpedia的实现技术:通过对WikiText格式数据进行语法解析和流程控制,实现对自由文本进行的结构化数据抽取和RDF表达,并基于URI参引、SPARQL查询和RDF文件转存等多种方法,实现多样化的Web数据获取;采用基于属性和基于模式的自动关联算法,与众多数据集之间实现关联。

Based on the principles and publishing method of linked data, this article introduces and analyses some technique issues of DBpedia. It extracts structured data from Wiki＇ s free text articles and expresses data in RDF by syntax parsing of WikiText and controlling of workflow. It also provides Web data in many ways such as URI dereference, search- ing based on SPARQL and RDF dumps. Finally, the paper uses automatic interlinking methods based on schema or properties algorithm to make linkages with a large amount of datasets.
