Analysis of Korea Science Citation Database's effect on JCR

Abstract

Citation analysis studies have reported many problems associated with data coverage problems common to popular citation databases such as Web of Science(WoS). In addition, the studies that analyzed citation patterns of Korean publications found that up to 75% of references in Korean publications were to international publications. As a first step in investigating the international coverage of WoS database, the study investigated the effect of adding citation data from Korea Science Citation Database(KSCD) to the impact factors and journal rankings of the journals listed in Journal Citation Reports. Specifically, the study mined the reference data from top 5 Korean Library and Information Science(KLIS) journals to recompute the impact factors reported in JCR 2009. Since the resulting journal rankings did not significantly differ from JCR 2009 rankings except for minor ranking changes, we analyzed additional citation data from 45 computer science and electrical engineering journals. Although the overall ranking difference was not statistically significant, one of the ranking partitions showed significant change. Such study findings despite its limited data sample suggest the potential impact of non-Western citation databases such as KSCD to bibliometric indicators provided by popular citation databases like WoS.

Analysis of the citation impact of national journals toward SCIE journals on JCR ranking

“…The Pearson correlation coefficients show the significant correlations in the overall ranges, except two ranges which have less than 0.6; the correlation coefficient for the range of 91 to 100 is lower than 0.5, which shows a very low correlation. This finding supports what Lee et al (2012) found from their JCR ranking change experiment. Therefore, this research confirmed that the citations by the Korean natural science and engineering journals in KSCD can significantly influence the ranking changes in the various subject areas of JCR.…”
