摘要
针对现有文献知识元链接存储技术在语义关系体现方面存在的不足,提出一种基于图数据库的文献知识元链接存储方法。该存储方法采用文献知识元抽取技术获取独立的、非RDF形式的知识元数据,利用关联数据相关技术对抽取的文献知识元和文献知识元链接进行语义描述,通过语义文献知识元数据和语义文献知识元链接数据与图数据库之间的映射将其存储于图数据库中,并对该存储方法进行了实验验证。实验结果表明,本文提出的存储方法有效地实现了文献知识元语义链接的图式存储。
Aiming at the shortage of semantic relation of the existing storage technology of literatureknowledge element linking,this paper proposes a storage method based on gragh database. This methodadopts literature knowledge elements extraction to obtain standalone and non RDF knowledge element da-ta,and describes it semantically by techniques of linked data.Then semantic literature knowledge ele-ments data and semantic literature knowledge elements linking data are stored in the graph databasethrough mapping with the graph database.Finally,we test the experiment of the storage mean.The resultshows that the proposed storage approach effectively implement the graph storage of literature knowledgeelement semantic linking.
