TITLE :COMPARATIVE ANALYSIS OF CITATION BASED SCIENTOMETRIC INDICATORS OF JOURNAL OF ASTROPHYSICS AND ASTRONOMY (JAA) AND JOURNAL OF THE KOREAN ASTRONOMICAL SOCIETY (JKAS) USING SCIMAGO JOURNAL RANK FOR THE PERIOD 2011-2020
Abstract :In academic circles, journal rankings are widely used to assess the impact and quality of academic journals. SCImago Journal Rank – A measure of scholarly journal scientific impact that considers the number of citations received by a journal and the importance or reputation of the journals from which such citations come. This paper compared the JAA and JKAS journals published from 2011 onwards, particularly in Physics and Astronomy, using citation-based analysis using the SCImago journal rank. This article discusses the year-by-year SJR, citation per document (four years, three years, and two years), self-citations and total citations, external citations and citations per document, percentage of international collaboration, citable and non-citable documents, cited and uncited documents. The SJR value for the last ten years shows that the highest SJR for JAA and JKAS journals is 0.631 in 2020 and 0.988 in 2018.2020 is the best year for four-year, three-year, and two-year citation per document, with 2.198, 2.464, and 1.855 for the JAA journal. 2018 is the best four-year and three-year citation per document year, with 2.546, 3.439and 2.954for JKAS, respectively. JAA received 82 self-citations and 1830 total citations, while JKAS received 132 self-citations and 1216 total citations, according to the SCImago ranking. The JAA journal received 10.328 external citations per document and 2.464 citations per document over the last ten years, while the JKAS journal received 14.143 external citations per document and 15.942 citations per document. For the last ten years, the JAA and JKAS have had a total percentage of internal collaboration of 180.86 and 297.4, respectively. According to SCImago records, the JAA published the most cited documents (97) in 2020 and the most uncited (144) in 2017. On the other hand, in the JKAS journal, there were 57 cited documents in 2017 and 43 uncited documents in 2016.
