“…Thus, the modified JIF values (i.e., MJIF2 or MJIF3) that exclude all the citations due to CIF show a substantial decline from their original JIF values. These results however differ to some extent from the findings of Alguliyev and Aliguliyev [45] where they advocated modified impact factor for journals after excluding JSC only. The deviation arises perhaps due to difference in number of optimising factors considered in deriving modified impact factor.…”

“…Though the effect of JSCs and ASCs on citation based impact measures have been studied individually at times, [33,35,[44][45][46] surprisingly, the unified effect of these optimizing factors on citation counts of a research entity is less explored. More recently, Giri [30] has made an attempt to examine the unified effects of these optimizing factors on citation counts of the journals empirically, where he took a synchronous publication year and a diachronous citation window.…”

Influence of a research journal is usually assessed in contemporary academia by Journal Impact Factor (JIF) given by Journal Citation Reports (JCR) published annually by Clarivate Analytics. JCR also provides Journal Immediacy Index (JII), an additional citation parameter which indicates current impact of journals. These citation based measures are simple arithmetic mean of raw citation counts to source publications. It is opined and empirically tested that three major extraneous citation optimizing factors i.e., Author self-citation (ASC), Journal self-citation (JSC) and Recitation (RC) can inflate these popular citation based metrics. This study examines nineteen Scopus index Library and Information Science (LIS) journals to understand individual as well as unified effects of these three optimizing factors on three popular impact indicators i.e., 2-year JIF, 3-year JIF and JII. It is found that ASC and JSC have noticeable effects on these impact indicators. Further, it is observed that these impact indicators exhibit very poor correlation among them when their values are deduced from raw citation counts, though all of them express simple arithmetic mean values. However, modified impact indicators calculated after excluding citations due to these optimizing factors, exhibit moderate to strong correlation among them. It is therefore concluded that more refined method that can automatically exclude the effect of these optimizing factors in their derivation may be needed for fair assessment of a journal's relative impact in scholarly communication.
