文献采购中平均文献信息距离比评价指标分析方法

Analytical Methods on Evaluation Index of Average Information Distance Ratio in Literature Acquisition

在图书馆实际工作中,文献采购大多依据采购人员经验和喜好,缺乏科学评价指标数据约束,存在很大的随意性和不稳定性。平均文献信息距离比作为一种全新的定量评价指标,突破定性分析的局限,能够科学地指导图书馆馆藏建设,使得文献采购更加科学、准确。

In the practical work of libraries, literature acquisition largely relies on experience and favors of acquisition personnel, lacks constraint of evaluation index and owns arbitrariness and instability. As a new quantitative evaluation index, average information distance ratio could break through limitations of qualitative analysis, guide library collection construction scientifically, and make literature acquisition more scientific and accurate.
