| Abstract: | Propose/Significance] Citescore is a new metricsto measure the citation impact for the journals,which was proposed by Elsevier in recent years.Investigating the feature and effectiveness of citescore is crucial for both development and improvement of the metrics for journal evaluation.Method/Process] In this paper,we took the journals in different fields of natural and social sciences as samples,and investigated the correlation among the citescores,impact factors and eigenfactors of these journals.At the same time,we also discussed the main features of citescore,and the intrinsic relationship and differences of three metrics,including citescore,impact factor and eigenfactor.Result/Conclusion] The results showed that compared with impact factor and eigenfactor,the citescore had more significant advantages in the database,citation time,literature type,calculation transparency and free access.Furthermore,the degree of correlation between citescore and impact factor was higher than that between citescore and eigenfactor.The degrees of correlation among citescore,impact factor and eigenfactor were associated with the disciplines of natural and social sciences. |
