基于实证比较的外文期刊数据库评价模型构建与应用

Establishment and Application of Foreign Journal Database Evaluation Model by Empirical Comparison

21世纪以来,数据库在图书馆采购资源中的比重不断上升,外文电子期刊作为最重要的电子资源,其绩效评价受到了广泛关注,也涌现了许多数据库评价研究。在总结分析现有评价研究的基础上,本研究将构建综合评价模型分解成评价指标遴选、数据采集及处理、指标权重设置3个重要环节,结合上海交通大学图书馆的实践经验,深入比较各环节对评价结果的影响,以期为建立和应用科学、合理、实用的数据库评价模型提供有益借鉴。

Since the beginning of the 21 st century,the proportion of databases has been rising greatly in library resources acquisition.It is of considerable interest to libraries to evaluate the performance of e-journal databases,the most important e-resources.As a result,databases evaluation has been extensively studied.After summarizing and analyzing the existing evaluation researches,this paper resolves the model into three key elements: evaluation indicators,data collection and processing,and indicator weights.Using the practical experience of Shanghai Jiao Tong University Library,the paper compares evaluation results by changing the model elements,in order to provide useful reference for the establishment and application of scientific,reasonable and practical database evaluation models.
