Abstract: |
Using co-word analysis and visual method, we clustered the key words of bioinformatics, and revealed the subject classification and hotspots of this subject. We got 5 707 bioinformatics related articles in the database of China National Knowledge Infrastructure (CNKI) and the Chinese medical association from 1998 to 2013.From these, we extracted 40 high frequency keywords. Based on these keywords, we established the co-word matrix using ROST software, and processed these data by factor analysis, clustering dendrogram, Multidimensional Scaling diagram using SPSS software. We divided the topics of bioinformatics research content into seven categories using factor analysis and cluster dendrogram. We also discussed the hotspots and tendency preliminarily using multidimensional scaling diagram.The results reflected the current subject classification and research hotspots objectively in the field of bioinformatics; our conclusions could provide a certain reference to scientific research community for bioinformatics. |
