摘要
从文献计量视角对我国科研仪器研究文献展开分析,通过可视化工具及潜在狄利克雷分配模型(LDA)进行文本挖掘揭示科研仪器研究的知识结构。分析发现以科研仪器为主题的文献数量增长迅速,作者合作密度较低,科研仪器研究主题覆盖范围在逐渐扩大;结合人工编码及LDA文本挖掘确定科研工作、科研基础、科研设备以及科研人员4个主题,其中科研工作与科研基础主题在我国科研仪器研究知识结构中占比较多,科研设备与科研人员主题的研究力量薄弱。
From the bibliometric perspective,this study analyzes the literature on scientific research apparatus in China and reveals the knowledge structure of scientific research apparatus through text mining with visual tools and the LDA model.It is found that the number of literatures on scientific research apparatus are increasing rapidly,the cooperation density of authors is low,and the coverage of research topics on scientific research apparatus is gradually expanding.Using manual coding and LDA text mining,four topics on scientific research work,scientific research basis,scientific research apparatus,and researchers are determined.Among them,research work and basic research themes account for more in the knowledge structure of scientific research apparatus in China,while the research strength of scientific research apparatus and researcher themes is weak.
