基于中介度揭示学科热点与传统词频统计法结果比较研究*--以链接分析领域为例

摘要

Purpose/Significance] Knowing the hotspots of a discipline can greatly help scholars to determine their research direction and promote a further development of the discipline. [ Method/Process] Through a comparative analysis of the results obtained by using the two methods of betweenness analysis and word frequency analysis to analyze the papers closely related to link analysis during 2002-2012 from CNKI, this paper obtains a new idea of discovering hotspots. [ Result/Conclusion] That is, the combination of the two methods of betweenness analysis and word frequency statistics can be more scientific and comprehensive in discovering the discipline hotspots.%[目的/意义]了解学科研究热点，有助于科研人员确定研究方向，进一步促进学科的繁荣与发展。[方法/过程]以链接领域为例，获取了2002-2012年间CNKI收录的与该领域研究密切相关的论文，利用词频统计及中介度两种方法揭示该领域热点，通过分析对比，以期得到一种揭示热点的新思路。将所获得的文献进行处理后，并对关键词进行增补、合并等处理后后得到所需数据。利用传统的词频统计法与基于中介度的方法对文献的关键词进行排序，通过对比分析两种方法所得到的结果，得出结论。[结果/结论]在研究学科领域的研究热点时，词频统计与中介度相结合的方法，可以更加科学而全面的揭示学科热点。
