| Abstract: | Purpose/Significance]The research aims at exploring the ESI indicator visualization technology and methods to improve the library’s subject knowledge service capabilities and level.Method/Process]The ESI data is integrated by R language programming technology, and the box plot, histogram and scatter plot of ESI index data are drawn by ggplot() function, and the ESI subject positioning, benchmarking comparison and development trend are evaluated.Result/Conclusion]The research shows that the method can comprehensively characterize the ESI indicators, accurately describe the position of the evaluated institutions in the 22 disciplines of ESI classification, and intuitively reflect the relative deviation and development of the institutions and benchmarking institutions trend. |
