【目的/意义】更加有效地组织图书馆数字资源。【方法/过程】构建了一个基于关联数据的图书馆数字资源语义互联模型,该模型主要包括六个层次结构,分别是数据层、标识层、描述层、本体层、逻辑层和应用层。然后,提出了该互联模型的具体实现方法,通过对图书馆数字资源的采集与标识、RDF元数据的构建、本体的设计与构建以及基于关联数据的语义推理和映射来实现图书馆数字资源的语义互联。【结果/结论】以图书馆元数据本体为实验数据,通过Fa CT++推理机和映射系统Falcon-AO进行实验,实现资源间的语义互联。
[Purpose / Significance] To organize library digital resources more effectively. 【Method / Process】 A semantic model of library digital resources based on relational data was constructed. The model mainly consisted of six layers: data layer, identification layer, description layer, ontology layer, logic layer and application layer. Then, the concrete realization method of this interconnection model is put forward. Through the collection and identification of digital resources of library, the construction of RDF metadata, the design and construction of ontology and the semantic reasoning and mapping based on related data, Semantic Internet. [Results / Conclusions] Taking the library metadata as experimental data, experiments were carried out by using Fa CT + inference engine and mapping system Falcon-AO to realize the semantic interconnection among resources.
