认为文献、研究领域的学科交叉性一般使用其参考文献的所属学科分类(subject category,SC)来分析,而WoS(Web of Science)提供的参考文献数据并不包含学科分类,因此,有必要研究如何通过参考文献获取学科分类并分析学科交叉性。以图书情报领域为例,从学科分类的数量、分布以及差异性的角度分析图书情报领域的学科交叉性并以叠加图(overlay map)进行可视化。指出利用参考文献的学科分类分析学科交叉性的方法可以扩展到其他研究领域。
It is considered that subject cross-references in literature and research are generally analyzed using the subject category (SC) of their references, whereas reference data provided by WoS (Web of Science) do not contain subject categories. Therefore, it is necessary to study How to Obtain Discipline Classification and Analyze Discipline Interdisciplinaryities by Reference. Taking the field of library and information science as an example, this paper analyzes the interdisciplinary aspects of library and information science from the perspectives of the number, distribution and diversity of subject categories and visualizes them with overlay maps. It is pointed out that the method of cross-disciplinary analysis of disciplines using references can be extended to other fields of research.
