面向关联数据的语义数字图书馆资源描述与组织框架设计与实现

摘要

本文提出了一个面向关联数据的语义数字图书馆资源描述与组织框架，该框架具有四个层次：元数据层、本体层、关联数据层和应用层，其核心是RDF语义元数据的构建与关联。以“图书、情报与档案学”领域的数据为例对该框架进行了实现，实现的重点是在本体层和关联数据层，包括相关本体的设计、普通元数据到语义元数据的自动转换、不同数据集间RDF语义链接的建立、关联数据的发布等。图5。参考文献46。%in this paper, the author proposed a linked data-oriented framework for resource description and organiza- tion in semantic digital libraries, which includes four layers--metadata layer, ontology layer, linked data layer and applica- tion layer. The core of the framework is the construction and linking of RDF-based semantic metadata. Using the data from the domain of "Library, Information & Archives" as an example, the author focused on the ontology layer and linked data layer to implement the framework, which involves the design of related ontologies, automatic transformation of traditional metadata into semantic metadata, construction of RDF semantic links among different datasets, and publishing of linked da- ta etc. 5 figs. 46 refs.
