A strategic diagram method for the analysis of the keywords in scientific papers is proposed. In order to eliminate the indexer effect, the paper selects the keywords from the keywords chosen by the authors, the keywords indexed by the machine, and the keywords extracted from the titles and abstracts. The selected keywords are clustered into research themes. The paper com- putes the centrality and density indexes of the research themes, draws their strategic diagrams, and divides the research themes in- to 4 categories for the analysis of the status quo of the problem domain. Moreover, the paper divides the data into several phases, and forms the strategic diagrams separately. By computing the similarity, provenance and influence indexes of the themes of the ad- jacent phases, the paper finds out the transformation of the research themes and their relations. The experiment verifies the effectiveness of the proposed method.%文章提出了科技论文关键词的战略图分析方法,从论文作者关键词、机器标引关键词和标题摘要中抽取的关键词中选择关键词,以消除标引效应,通过聚类将关键词划分为研究主题簇,计算研究主题簇的向心度指标和密度指标,绘制战略图,将研究主题簇分为4类,据此分析问题领域现状;将数据分为若干阶段,分别形成战略图,通过计算相邻阶段的主题簇的相似度指标、起源指标和影响指标,了解研究主题变迁和相互关系。实验证明了战略图分析方法的有效性。
