摘要
本文运用科学计量学方法对近20万条力学SCI专业期刊论文数据进行统计和分析,得到了前20个高频关键词的共现矩阵。通过对前20个高频关键词的共词分析,利用Jaccard指数考察了前20个高频关键词之间的关系,并用知识图谱的方法映射出固体力学和流体力学研究内容之间的复杂网络关系。
This paper used sientometrics to research co - keywords of international mechanical paper, and explored main fields of international mechanics and their relations. Through the data from SCI, building co- keyword matrix of top 20 keywords, and mapping the relations between top 20 keywords, it could safely infer to main fields of international mechanics and their relations.
