DBPEDIA项目是社区努力，旨在从Wikipedia中提取结构化信息，并使此信息在网络上访问。由此产生的DBPEDIA知识库目前描述了超过260万个实体。对于这些实体中的每个实体，DBPedia都定义了一个全球唯一的标识符，可以通过网络将其重新引入到该实体的丰富RDF描述中，包括30种语言的人类可读定义，与其他资源的关系，四个概念层次结构中的分类，各种事实，各种事实以及描述实体的其他Web数据源的数据级链接。在过去的一年中，越来越多的数据发布者开始将数据级链接设置为DBPEDIA资源，使DBPEDIA成为新兴数据网络的中间互联枢纽。目前，DBPEDIA围绕的相互联系的数据源网络提供了约47亿个信息，并涵盖了地理信息，人员，公司，电影，音乐，基因，毒品，书籍和科学出版物等领域。本文介绍了DBPEDIA知识库的提取，即与网络上其他数据源相互联系的当前状态，并概述了促进DBPEDIA数据网络的应用程序。 （c）2009 Elsevier B.V.保留所有权利。
The DBpedia project is a community effort to extract structured information from Wikipedia and to make this information accessible on the Web. The resulting DBpedia knowledge base currently describes over 2.6 million entities. For each of these entities, DBpedia defines a globally unique identifier that can be dereferenced over the Web into a rich RDF description of the entity, including human-readable definitions in 30 languages, relationships to other resources, classifications in four concept hierarchies, various facts as well as data-level links to other Web data sources describing the entity. Over the last year, an increasing number of data publishers have begun to set data-level links to DBpedia resources, making DBpedia a central interlinking hub for the emerging Web of Data. Currently, the Web of interlinked data sources around DBpedia provides approximately 4.7 billion pieces of information and covers domains such as geographic information, people, companies, films, music, genes, drugs, books, and scientific publications. This article describes the extraction of the DBpedia knowledge base, the current status of interlinking DBpedia with other data sources on the Web, and gives an overview of applications that facilitate the Web of Data around DBpedia.
