研究专业演化图谱及其应用研究

On Research Specialty Evolution Mapping and Its Application

本文在作者关键词耦合分析方法的基础上，提出利用研究专业演化图谱对研究领域演化进行分析的方法。并进行了实证研究。作者关键词耦合分析所得到的作者类团具有“研究专业”的特点，因此可将其作为分析单元探索研究领域的整体演化。本文所提出的研究专业演化图谱以研究专业为分析单元，通过图谱中研究专业规模、研究专业年龄以及研究专业间关系的变化来展示整个研究领域的变化情况。在海洋科学领域的实证表明，研究专业演化图谱不仅可以很好的展示海洋科学领域的整体发展，而且还可以发现领域内各研究专业的演化及其关系。

Based on Author Keyword Coupling Analysis （AKCA）, the Research Specialty Evolution Mapping is proposed and tested by empirical research. The Clusters of Authors found by AKCA have the features of ＂ Research Specialty＂, Which can be used as basic unit for analysis of research field evolution. Research Specialty Evolution Mapping makes the research specialty as the basic unit, and the whole research field evolution is represented by research specialties＇ scale, age, as well as similarities among them. The empirical research in Oceanography indicates that Research Specialty Evolution Mapping reflects the field＇s evolution, not only in the overall trend, but also research specialty evolution respectively.
