【摘要】：随着时代进步和科学技术的发展,海量信息资源不断涌入到学科建设过程中,促使很多学科领域的内容得到急速扩充,原有的学科结构也随之改变。如何及时、准确地展现客观存在的学科结构,发现学科演化轨迹,逐渐成为学者们关注的焦点。通过对学科结构和演化轨迹研究,学者可追踪学科研究热点和前沿,发现影响学科融合、裂变的因素,把握学科发展规律。本文通过对图书情报领域近5年核心期刊中的关键词、主题、作者、文献等知识单元进行分析,利用内容分析、共词分析、聚类分析、共被引和合作网络分析等多种计量方法,从微观、中观到宏观三个角度分别对学科结构和学科演化进行分析,得到如下结论:(1)学科演化确实存在生命周期,并受到内外两种因素的影响,出现融合、分裂、扩充、消失、重组等一系列演化现象。(2)从关键词和作者两个方面分别进行学科结构研究,发现利用关键词研究学科主题得到的结论较为客观,而基于作者合作的研究弥补了关键词分析的不足,单从文献单元视角分析学科结构不能观测到整体学科发展的脉路。(3)只有将学科结构与学科演化结合起来,才能完整地体现出学科的发展趋势,两者之间相互促进。一方面有突破性研究的发现,必能推动另一方面研究的进展。单独研究任何一方面都达不到本论文研究的预期效果和目的。
[Abstract]:With the progress of the times and the development of science and technology, massive information resources are constantly pouring into the course of discipline construction, which makes the contents of many disciplines expand rapidly, and the original subject structure also changes. How to show the objective structure of the subject and discover the evolution of the subject in time and accurately has gradually become the focus of attention of scholars. By studying the structure and evolution of the subject, the scholars can trace the hot spot and the frontier of the subject, find out the factors that influence the fusion and fission of the subject, and grasp the law of the discipline development. Based on the analysis of key words, themes, authors, literature and other knowledge units in core journals in the field of library and information in the past five years, this paper makes use of various metrological methods, such as content analysis, coterm analysis, cluster analysis, co-citation and cooperative network analysis, etc. This paper analyzes the structure and evolution of discipline from three angles of microcosmic, meso and macro, and draws the following conclusion: there is a life cycle in the evolution of discipline, and it is influenced by the internal and external factors, such as merging, splitting, expanding and disappearing. A series of evolutionary phenomena, such as recombination, have been carried out in terms of key words and authors, and the conclusions obtained by using keywords to study subject topics are more objective. But the research based on the author's cooperation makes up for the lack of keyword analysis, only can not observe the whole development of the subject from the perspective of document unit, only combine the subject structure with the evolution of the discipline. In order to reflect the development trend of the discipline, the two promote each other. On the one hand, the discovery of breakthrough research will promote the development of research on the other hand. No single study can achieve the expected effect and purpose of this paper.
