通过对《书目记录的功能需求》(FRBR)概念模型体系结构中实体、属性及关系这3个基本要素的分析,探寻由FRBR模型抽取出的馆藏资源元数据关联网络的构成要素,并对符合FRBR的馆藏资源元数据知识节点与关联关系所构成的关联网络结构进行层次划分,形成以元数据记录属性为支撑的微观层面关联网络及以元数据记录之间或规范数据集之间关联关系作为支撑的宏观层面关联网络。而词汇集的建立、术语复用机制、数据集链接桥机制成为构建馆藏资源元数据关联网络的基本要素。馆藏资源元数据关联网络的建立对于揭示馆藏资源内部的知识结构、扩展知识检索的范围、推荐关联知识、辅助知识发现等均具有重要的价值。
Through the analysis of the three basic elements of entity, attribute and relationship in the “Functional Requirements of Bibliographic Records” (FRBR), we explore the elements of the metadata network of collection resources extracted by FRBR model, FRBR’s resource metadata metadata nodes and associated network structures are hierarchically divided to form a micro-level related network supported by metadata record attributes and supported by metadata records or the relationship between normative data sets The macro level of the associated network. The establishment of lexical sets, the term reuse mechanism, and the data set link bridging mechanism become the basic elements for constructing the metadata network of collection resources. The establishment of the metadata network of collection resources is of great value for revealing the knowledge structure inside the collection resources, extending the scope of knowledge retrieval, recommending the associated knowledge and assisting the knowledge discovery.
