電子計量應用在電子期刊評鑑

The Application of E-Metrics to Electronic Journal Evaluation

學術圖書館由於網路環境形成而大量引進電子期刊，但也常引發下列問題：電子期刊與服務帶給使用者有何不同？因此促成在網路環境下評鑑電子期刊的需求。但是目前遭遇許多困難：如在動態與複雜環境中如何發展績效測量；太多評鑑活動需要花費許多時間；以及從代理商資料庫取得統計資料十分困難。本論文旨在探討電子計量應用在電子期刊的評鑑，首先探討電子期刊資源與管理的特質；其次說明電子期刊評鑑的困難與電子計量法意涵。基於電子計量與使用統計，本論文提出電子期刊電子計量評鑑的理論、方法以及個案研究。最後對我國電子期刊評鑑未來發展提出建議。

Electronic journals (E-journals) are popularly and extensively used in academic libraries. They involve a variety of publishers, aggregators, database producers, abstracts, and indexing services with different charging systems. In view of the various elements of E-journal composition, the evaluation of E-journals is necessary and significant. This paper mainly discusses the issue of E-journal evaluation by exploring the applications of E-metrics and performance assessment. This subject of study includes researches on evaluation indicators, evaluation procedures, data collection, data usage analysis, usage reporting, and usage statistics. Three case studies are involved in this paper, including the application of usage-based metrics on evaluation executed by the University of Maryland, the ARL E-metrics project, and the analysis of E-journal usage carried out by the University of Nevada, Reneo. The results acquired from this study suggest that E-metrics and performance assessment may serve as beneficial methods for E-journal evaluation while applied to multiple contexts of libraries and their parent institutions. They may significantly create new models of E-journal management.
