将Web of Science文章重新分类为独特主题类别和广泛学科的实用方法

Practical method to reclassify Web of Science articles into unique subject categories and broad disciplines

Staša Milojević

摘要:

在大型数据库中将书目项目分类为主题和学科对于许多定量科学研究是必不可少的。Web of Science将期刊分为约250个主题类别,这是许多研究的基础,已知有一些基本问题和一些实际限制,可能会影响这些研究的结果。在这里,我们提出了一个易于复制的方法来执行重新分类的Web的科学到现有的主题类别和14个广泛的领域。我们的重新分类是在文章的水平上,因此它保留了同一期刊上发表的个别文章之间可能存在的学科差异。重新分类还消除了50%的条目中存在的模糊(多个)类别,并为来自广泛覆盖的期刊(如《自然》和《科学》)的所有文章分配学科/领域类别。手动评估指定主题类别的正确性,发现其正确性约为95%。

英文摘要:

Classification of bibliographic items into subjects and disciplines in large databases is essential for many quantitative science studies. The Web of Science classification of journals into ~250 subject categories, which has served as a basis for many studies, is known to have some fundamental problems and several practical limitations that may affect the results from such studies. Here we present an easily reproducible method to perform reclassification of the Web of Science into existing subject categories and into 14 broad areas. Our reclassification is at a level of articles, so it preserves disciplinary differences that may exist among individual articles published in the same journal. Reclassification also eliminates ambiguous (multiple) categories that are found for 50% of items, and assigns a discipline/field category to all articles that come from broad-coverage journals such as Nature and Science. The correctness of the assigned subject categories is evaluated manually and is found to be ~95%.
