A Study of Evolution in Genomics by Scientometric Method
基因组学领域演进的科学计量研究

Using a collection of papers gathered from Web of Science on the research field of genomics,this study demonstrates the evolution process of genomics in knowledge dimension from 1991-2006.Based on high frequency keywords co-occurrence matrix of three different stages,multidimensional scaling method disposes the diversity among keyword co-occurrence relationship in different evolution stages,further analysis shows that the related research in genomics is still in adolescence period.In addition,the principal component analysis exhibits the dynamics among research topics in 16 years.The case study reveals the bibliometric method introduced in this paper can be used to extract large amounts of useful information in a research speciality.
