从学科和期刊的引证视角看交叉学科的知识结构和演化问题——以图书情报学科为例的实证研究

The Knowledge Structure and Evolution of Interdisciplinary Subjects from the Citation Perspective of Discipline and Journals:A Case Study of Library and Information Science

[目的／意义]随着信息技术的高速发展，学科之间的交叉融合趋势越来越明显，探索学科间知识交流活动，明确学科结构，对其学科发展具有重要意义。以图书情报学科为例，观察其知识的流入与输出情况，包括知识从哪个学科哪些方面流入以及输出到哪些学科哪些方面。[方法／过程]选择图书情报领域12种核心期刊作为数据来源，以CNKI的学科分类为标准进行学科划分，使用可视化软件工具Gephi，从参考和引证两个角度探讨图书情报学科与其他学科间的交叉融合情况。[结果／结论]图书情报学科与计算机科学、基础科学综合、经济管理等学科联系紧密，学科结构趋于稳定；图书情报学科的参考总量远远小于被引总量；自引率呈逐年下降趋势，和外部学科交流频繁。

[ Purpose/signifieance] With the rapid development of information technology, the trend of cross-inte- g＇ration between disciplines isbecoming more and more obvious. It is of great significance to explore the interdisciplinary knowledge exchange activities and clear the structure of disciplines. This paper takes the library and information science （LIS） as an example to observe the inflow and outflow of knowledge, including the disciplines and directions of knowledge inflow and outflow. [ Method/process] We selected twelve core journals in the field of LIS as the data sources, anddivid- ed the disciplines according to CNKI＇ s discipline classification. Finally, we used Gephi （a visualization software tool） , to explore the intereross between LIS and other disciplines from the perspective of reference and citation. [ Result/conclu- sion] This paper reveals that：L IS is closely related to the disciplines of computer science, basic science synthesis , eco- nomic managementand so on, and the disciplinary structure tends to be stable ; the total reference volume of LIS is far less than that of citation; the self-citing rate of LIS has been declining year by year, and the exchangeof LIS with external dis- ciplines is frequent.
