1.3 Visualized map analysis of co-keywords
The keywords with highest frequency are always the indicator of hot topics in a certain researching field. Thus,
this paper analyzed the co-occurrence networks of keywords of the articles in the genomics related fields in order
to explore the research hot spots and their evolution.
