基于特色关键词的科研机构研究主题揭示：方法与实证

在提示科研机构研究主题特征时，传统研究方法过于依赖高频词，以致分析结果不够深入具体。针对这一问题，提出关键词的机构归属度指标，以便提取科研机构中的特色关键词。在实验中，从图书情报学科8个主要机构研究文献集中提取各机构的特色关键词，并依此揭示它们各自的研究特色和相近研究主题侧重点的差异。分析表明，该方法的结果能很好地还原这些机构的自身定位、研究背景与发展现状。

Method and Empirical Study on Revealing the Research Themes Characteristics of Research Institutions Based on Specific Keywords

In revealing the research theme characteristics of research institutions, the traditional research relies too heavily on high-frequency keywords to result in the vague and general analysis results. This paper proposes an index called institution relevancy of keywords to select the specific keywords of research institutions. As an experiment, 8 major institutions are analyzed and compared based on their specific keywords selected by the new method, to reveal their own research characteristics and different emphasis of similar research themes. The result proves that the method can effectively restore the self-positioning, research background and realistic situation of those institutions.
