鏈結資料公用目錄的評估初探

An Evaluation Approach for Linked Data Public Access Catalogs

因應鏈結資料的應用發展，近年已有許多圖書館導入鏈結資料，提供更多的線上公用目錄資訊服務。本文旨在探討鏈結資料公用目錄的發展現況，以文獻探討分析歸納的11項功能服務為依據，選取具有豐富書目本體論語意關係的Jane Austen與其相關作品及相關衍生作品與個人為測試樣本，針對西班牙國家圖書館、法國國家圖書館，及美國國會書館鏈結資料系統與LD4P計畫之一的共享型虛擬探索環境（SHARE-VDE）等4個案例對象實際評估。研究結果發現4個案例已大致具備鏈結化資源探索等11項功能外，特色不盡相同，包括脈絡化公用目錄、鏈結資料公用目錄類型、鏈結資料化方式、URI鏈結化程度、語意關係與開放程度等。此外，本文亦就鏈結資料公用目錄與資源探索系統加以比較。

With the application and development of linked data (LD), libraries have begun to offer LD-based information services for users. This study uses a checklist-based evaluation derived from a literature review as a research tool to address the state-of-the-art development and issues related to LD public access catalogs (PACs). Jane Austen and her works as well as derived works and persons were selected as testing instances for LD PAC at four libraries as follows: Biblioteca Nacional de España, Bibliothèque nationale de France, Linked Data Service of Library of Congress and SHARE Virtual Discovery Environment. Eleven functions were included in the evaluation checklist. The degree of provision of each function by each LD public access catalog was found to be varied in terms of link-based resource discovery, linkage to external LD resources and types, self-descriptive and dynamic content, representation and query of LD relationship, aggregated knowledge contexts, information graph, serendipity, toURIsm navigation, facet based navigation, reconfiguration and repackage, keyword recommendation and openness of data. A comparison between resource discovery system and LD PACs is also presented.
