摘要
针对学科领域中热点研究主题探测,尝试综合运用共词分析方法与自组织映射(SOM)方法,在词频统计的基础上,分析高频主题词在文献中的共现,并作为输入数据利用SOM Toolbox进行SOM聚类分析,得到领域热点研究主题。以传统医药领域为例进行实证分析,结果表明该方法对领域中热点主题探测有一定效果。
According to detection of hot topics in a research field, the paper proposes a method combining co -word a- nalysis and SOM together. By analysing the co - occurrence of high - frequency keywords in the literature as input data and using SOM Toolbox for SOM clustering, the collection of hot research topics is obtained. At last a case study is done by taking traditional medicine as an example, and experimental results show that this method is efficient in the process of hot research topics detection.
