| Abstract: | Purpose/significance]Aiming at the quantification of double-base and multi-base indicators of con-tent quality of foreign journal database,a multi-base comparison algorithm based on unified journal space is pro-posed,which realizes the journal identification and comparison between arbitrary multi-bases,and improves the quantification accuracy of these indicators.Method/process]On the basis of analyzing the content and complexity of the content quality indicators of foreign journal databases,this paper designed a multi-database comparison algo-rithm based on unified journal space,and used this algorithm to calculate the number of JCR journals and the number of unique journals of 57 databases in DRAA in 2018,as a verification of the validity and accuracy of the algorithm.Result/conclusion]As an extension study of various electronic resource evaluation indicator systems,this study can help libraries optimize their collection construction and make the purchase of foreign journal databases more eco-nomical and reasonable. |
