DBpedia社区项目从维基百科中提取结构化的多语言知识，并使用语义网和关联数据技术在网络上免费提供这些知识。该项目从111种不同语言版本的维基百科中提取知识。从英文版维基百科中提取的最大的DBpedia知识库包含超过4亿个事实，描述了370万个事物。从其他110种维基百科版本中提取的DBpedia知识库总共包含14.6亿个事实，并描述了另外1000万个事物。DBpedia项目将27种不同语言版本的维基百科信息框映射到一个由320个类别和1650个属性组成的单一共享本体。这些映射是通过全球众包努力创建的，使得来自不同维基百科版本的知识能够被整合。该项目发布所有DBpedia知识库的版本供下载，并通过本地DBpedia分会的全球网络为111种语言版本中的14种提供SPARQL查询访问。除了常规发布之外，该项目还维护一个实时知识库，每当维基百科中的页面发生变化时就会更新。DBpedia设置了2700万个RDF链接，指向30多个外部数据源，从而使这些数据源的数据能够与DBpedia数据一起使用。网络上有数百个数据集发布指向DBpedia自身的RDF链接，使DBpedia成为关联开放数据（LOD）云中的核心互联枢纽之一。在这份系统报告中，我们对DBpedia社区项目进行了概述，包括其架构、技术实现、维护、国际化、使用统计和应用。
The DBpedia community project extracts structured, multilingual knowledge from Wikipedia and makes it freely available on the Web using Semantic Web and Linked Data technologies. The project extracts knowledge from 111 different language editions of Wikipedia. The largest DBpedia knowledge base which is extracted from the English edition of Wikipedia consists of over 400 million facts that describe 3.7 million things. The DBpedia knowledge bases that are extracted from the other 110Wikipedia editions together consist of 1.46 billion facts and describe 10 million additional things. The DBpedia project maps Wikipedia infoboxes from 27 different language editions to a single shared ontology consisting of 320 classes and 1,650 properties. The mappings are created via a world-wide crowd-sourcing effort and enable knowledge from the different Wikipedia editions to be combined. The project publishes releases of all DBpedia knowledge bases for download and provides SPARQL query access to 14 out of the 111 language editions via a global network of local DBpedia chapters. In addition to the regular releases, the project maintains a live knowledge base which is updated whenever a page in Wikipedia changes. DBpedia sets 27 million RDF links pointing into over 30 external data sources and thus enables data from these sources to be used together with DBpedia data. Several hundred data sets on the Web publish RDF links pointing to DBpedia themselves and make DBpedia one of the central interlinking hubs in the Linked Open Data (LOD) cloud. In this system report, we give an overview of the DBpedia community project, including its architecture, technical implementation, maintenance, internationalisation, usage statistics and applications.
