Abstract

Many libraries have deployed discovery layers to bring various library resources under a single search interface. These tools, which mostly rely on keyword indexing, do not easily bring together items on similar topics described under different thesauri. Michigan State University Libraries (MSUL) undertook an experimental project to enhance subject discovery through subject knowledge cards that utilize subject authority data and linked open data (LOD). Subject knowledge cards are currently deployed in the MSUL digital repository to improve the subject discovery experience by displaying contextual information on the subject, links to repository items on broader, narrower and related subjects, and links to external library resources on the same subject. This approach demonstrates a new way to enhance the subject discovery experience through LOD.

摘要

许多图书馆部署了发现层，将各种图书馆资源置于单一搜索界面下。这些工具主要依赖于关键字索引，不能轻易地将不同叙词表下描述的相似主题的项目放在一起。密歇根州立大学图书馆 (MSUL) 开展了一个实验项目，通过利用学科规范数据和链接开放数据 (LOD) 的学科知识卡来增强学科发现。学科知识卡目前部署在 MSUL 数字知识库中，通过显示有关学科的上下文信息、指向更广泛、更狭窄和相关学科的知识库项目的链接以及指向同一学科的外部图书馆资源的链接，来改善学科发现体验。这种方法展示了一种通过 LOD 增强主题发现体验的新方法。
