中文简介: | 链接数据网络包含约250亿个RDF三元组和近5亿个跨数据源的链接;它正成为语义应用程序的重要资产。关联数据包括大型通用知识库,如DBpedia、Yago和Freebase,以及跨越科学、文化、娱乐等广泛领域的许多参考文献集。尽管关联数据具有巨大的潜力,但本次演讲认为,要取得进一步进展,还需要克服重大局限性。这些限制涉及数据范围,特别是数据质量。讲座讨论了这些问题以及扩展和丰富关联数据的方法,以提高其范围、质量、可解释性、交联性和有用性。 |
课程简介: | The Web of Linked Data contains about 25 billion RDF triples and almost half a billion links across data sources; it is becoming a great asset for semantic applications. Linked Data comprises large general-purpose knowledge bases like DBpedia, Yago, and Freebase, as well as many reference collections in a wide variety of areas, spanning sciences, culture, entertainment, and more. Notwithstanding the great potential of Linked Data, this talk argues that there are significant limitations that need to be overcome for further progress. These limitations regard data scope and, especially, data quality. The talk discuss these issues and approaches to extending and enriching Linked Data, in order to improve its scope, quality, interpretability, cross-linking, and usefulness. |
