Citation Analysis of Hepatitis Monthly by Journal Citation Report (ISI), Google Scholar, and Scopus.

Miri SM, Raoofi A, Heidari Z - Hepat Mon (2012)

Bottom Line: None of the three databases succeed to record all articles published in the journal.Using an average of three IFs is suggested to find the correct IF.Editors should be more aware on the role of original articles in increasing IF and the potential efficacy of review articles in long term impact factor.

ABSTRACT

Background: Citation analysis as one of the most widely used methods of bibliometrics can be used for computing the various impact measures for scholars based on data from citation databases. Journal Citation Reports (JCR) from Thomson Reuters provides annual report in the form of impact factor (IF) for each journal.

Objectives: We aimed to evaluate the citation parameters of Hepatitis Monthly by JCR in 2010 and compare them with GS and Sc.

Materials and methods: All articles of Hepat Mon published in 2009 and 2008 which had been cited in 2010 in three databases including WoS, Sc and GS gathered in a spreadsheet. The IFs were manually calculated.

Results: Among the 104 total published articles the accuracy rates of GS and Sc in recording the total number of articles was 96% and 87.5%. There was a difference between IFs among the three databases (0.793 in ISI [Institute for Scientific Information], 0.945 in Sc and 0.85 GS). The missing rate of citations in ISI was 4% totally. Original articles were the main cited types, whereas, guidelines and clinical challenges were the least ones.

Conclusions: None of the three databases succeed to record all articles published in the journal. Despite high sensitivity of GS comparing to Sc, it cannot be a reliable source for indexing since GS has lack of screening in the data collection and low specificity. Using an average of three IFs is suggested to find the correct IF. Editors should be more aware on the role of original articles in increasing IF and the potential efficacy of review articles in long term impact factor.

Mentions: Among all published articles, two systematic reviews from Iran had the most citations which one of them was published in 2008 (n = 9) and another in 2009 (n = 7). Even though, there was a difference between the calculated IF in GS and Sc with ISI, Table 3 demonstrated that the mentioned difference was shown only in a few articles. The main discrepancy was in one original article published in 2009. According to data from GS this article is cited 5 times comparing to ISI and Sc which was two times. Figure 1 shows that among articles published in Hepat Mon during 2008 and 2009, original articles were the main cited types while guidelines and clinical challenges were the least types. Whereas if we consider proportion of citations to the types of articles, review articles have the most citation. Furthermore, case reports were the only type of articles which were the same in citation numbers in all the databases (Figure 1). No significant difference was detected in all other types of articles except original articles which represented a significant difference between ISI and the two other databases.
